[0002]

[Prior art]

Conventional example 1. FIG. 75 is a block diagram of a conventional example. A main memory 700 that stores a circuit diagram image, a command menu, and a circuit symbol menu, and graphic display means 90 that reads the graphic data stored in the main memory 700 and converts the coordinates of the graphic data into the coordinate system of the display device 1000.
0, the display device value 1000 for displaying the graphic output by the graphic display means 900, and the display device 100.
The pointing device 100 for inputting coordinates on 0 and the coordinates input by the pointing device 100 are stored in the main memory 700.
Coordinate input means 200 for converting to the above coordinate system and writing in the main memory 700, and command control means 8 for controlling commands
00, the command symbol control unit 800 controls the circuit symbol placement position designating unit 300 for designating the selection and placement position of the circuit symbol, and the circuit symbol placement position designating unit 300. The graphic duplication detection unit 400 and the existing wiring deletion unit 500 that is activated by the graphic duplication detection unit 400 and deletes the overlapping portion of the existing wiring that overlaps the leader line of the circuit symbol among the existing wiring that overlaps with the circuit symbol. And an already-routed route changing unit 600 that is activated by the figure duplication detection unit 400 and changes the route of an already-existing line that does not overlap the leader line of the circuit symbol among the already-routed lines that overlap the circuit symbol. To be done.

The operation will be described with reference to FIGS.
In FIG. 76, it is assumed that the circuit symbol shown in FIG. 77 is inserted between the circuit symbols C1 and C2 and the circuit symbol C3. The graphic display means 900 is a main memory 700.
The circuit diagram shown in FIG. 76 and the command menu expanded in FIG. First, the operator operates the pointing device 100 from the command menu displayed on the display device 1000 and clicks the command corresponding to the circuit symbol arrangement position instructing means 300. The coordinate input means 200 writes the coordinates clicked by the pointing device 100 in the main memory 700. Next, the command control means 800 reads the main memory 700 and activates the circuit symbol arrangement position designating means 300 corresponding to the clicked coordinate. The circuit symbol arrangement position designating means 300 writes the circuit symbol menu in the main memory 700. The graphic display means 900 reads the main memory 700 and displays it on the display device 1000.

Next, the operator operates the display device 100.
The pointing device 100 is operated from the circuit symbol menu displayed in 0 and the circuit symbol shown in FIG. 77 is clicked. The coordinate input means 200 writes the coordinates clicked by the pointing device 100 in the main memory 700. Next, the circuit symbol arrangement position instructing means 300 reads the main memory 700 and selects the circuit symbol menu for the clicked coordinate to make it movable. As a result, the circuit symbol moves in synchronization with the pointing device 100. Next, the operator operates the pointing device 100 to display the selected circuit symbol in FIG.
It is placed at the position of the circuit symbol C4 shown in 8 and the coordinate is clicked. The coordinate input means 200 writes the coordinates clicked by the pointing device 100 in the main memory 700. Next, the circuit symbol arrangement position designating means 300 reads the main memory 700, fixes the circuit symbol at the clicked coordinate, and activates the figure duplication detecting means 400.

Next, the graphic duplication detection means 400 checks by the circuit symbol placement position designating means 300 whether or not the placed circuit symbol and the existing wiring overlap. When there is an overlap, and when there is an existing wire which overlaps with the leader line of the circuit symbol, the existing wire deleting means 500 is activated. If there is overlapping, but there is no existing wiring overlapping with the leader line of the circuit symbol, the already-routed route changing means 600 is activated. Next, the existing wiring deletion means 500 deletes the existing wirings 11 and 12 in the circuit symbol C4 and writes them in the main memory 700, as shown in FIG. Next, the existing wiring route changing means 600
As shown in FIG. 80, the existing wiring l3 overlapping the circuit symbol C4 is pushed down. Then, since the overlap caused by pushing down the wiring l3 occurs between the wirings l3 and l4, the wiring l4 is pushed down. The result is written in the main memory 700. Next, the graphic display means 900 reads the circuit diagram image written in the main memory 700 and displays it on the display device 1000.

Conventional example 2. Depending on the procedure for creating a drawing, data that is unpredictable from the appearance of the drawing may be created. For example, where the end point information representing one line segment should be (X1, Y1), (X3, Y1),
(X1, Y1), (X2, Y1) and (X2, Y1),
Sometimes it was registered as two line segments (X3, Y1). At this time, when the figure is moved, only a part of it (for example, line segments (X1, Y1), (X2, Y1)) is moved, and other line segments (for example, line segments (X2, Y1), (X3 , Y
1)) was left and the continuity of the drawings was lost.

Conventional example 3. In the example shown in FIG. 81 (1), line attributes (D7, B8 in the figure) indicating the thickness, color, and number of the connecting line are input near the connecting line in the electric circuit diagram. However, as shown in FIG. 81 (2), the line attribute corresponding to the connecting line may be separated due to the movement of the circuit drawing or the movement of the line attribute. Even in this case, since D7 and B8 are defined as line attributes at the time of input, when the relationship between the connecting line and the line attribute is output, D7 and B8 are output as the line attributes of the connecting lines i and j, respectively. It

The control unit 7 includes a connecting line synthesizing unit 8, a connecting line dividing unit 9, a determining unit 10, and a moving unit 11. The function of the connecting line synthesizing means 8 will be described with reference to FIGS. FIG. 5 shows a case where the connecting line synthesizing unit 8 synthesizes two lines that overlap in a partial section into one line. In the figure, (1) shows the connection line a. The connection line a has M and N as end point coordinates. The connection line b to be added is shown in (2).

Are connected vertically. At this time, if the connection line c is deleted, as shown in (2), the connection line a and the connection line b are left with their end point coordinates P, N, and Q arranged on a straight line. The connection line synthesizing means 8 synthesizes the connection line a and the connection line b to form the connection line d as shown in (3). The end point coordinates of the connection line d are P and Q.

The function of the connecting line dividing means 9 will be described with reference to FIG. The connection line a is shown in (1). The end point coordinates of the connection line a are M and N. As shown in (2), the connection line b is added to the connection line a. The connecting line b is connected to the connecting line a at the coordinate P.

It should be noted that the connecting lines in FIGS. 5 to 7 do not have to be parallel to any of the x and y orthogonal coordinates.

The discriminating means 10 discriminates a 0th-order figure, a 1st-order figure, a secondary line, or a figure element for a group frame as shown in FIG. The function of the moving means 11 will be described below. The rules for moving the group frame differ depending on whether it is a 0th-order figure, a 1st-order figure, or a 2nd-order figure. (1) Moving the parts included in the group frame and the 0th-order figure which is a connecting line. (2) Movement of the primary connecting line connected to the 0th-order figure. (3) Movement of secondary vertical connection lines other than 0th order connected to the primary horizontal line and secondary horizontal connection lines other than 0th order connected to the primary vertical line. (4) Special rubber band wire is generated. Primary parts are parts that only partially overlap within the group frame.
When the pin of the part is connected to the 0th-order figure, the line automatically generated from the pin as it moves is called a special rubber band line.

The calculation rule of the coordinate value of the connection line after the movement for each classification is shown below. The displacement amount of movement is dx and dy. (1) Rule of movement of 0th-order figure FIG. 8 shows movement of 0th-order figure. In the figure, the figure surrounded by the one-dot chain line group frame is the state before the movement. Since all the figures to be moved are included in the group frame, they are 0th-order figures. Here, the end point (X, Y) of the connection line b is taken as an example. The state after the movement is a figure surrounded by a dotted group frame. The connection line b becomes a connection line b '. When the coordinate value of the 0th-order figure before the movement is (X, Y), it becomes (X + dx, Y + dy) after the movement.

(2) Primary Line Movement Rule FIGS. 9 to 11 are diagrams used to explain the primary line movement rule. The end point in the group frame with the primary line (X
_IN, Y _IN), the end point of the group outside the frame (X _{ou t,} Y _out)
And The coordinates after movement are (X _IN ', Y _IN '), (X
_out ', Y _out '). (A) The primary horizontal connection line is connected to the secondary line, or the end point outside the frame is not connected to the pin of the part or the end point of the oblique line. FIG. 9 (1) is a diagram when the primary horizontal connection line is connected to the secondary line. FIG. 9 (2) is a diagram in the case where the end point outside the frame of the primary horizontal connection line is not connected to the pin of the part or the end point of the oblique line. In both figures, the primary horizontal connecting line (dashed line) moves to the primary horizontal connecting line (solid line) as the group frame moves. Next, the calculation rule of the coordinate value of the connection line after the movement will be shown. X _IN '= X _IN + dx Y _IN ' = Y _IN + dy X _out '= X _out Y _out ' = Y _out + dy The coordinates of the end points in the group frame move in the X and Y directions as the group frame moves. However, the end points of the primary line outside the group frame move only in the Y direction, and the value in the X direction does not change. (B) When the endpoints of the primary horizontal connecting line outside the frame are connected to the pins of the parts or to the diagonal line endpoints.
FIG. 10 (3) is a diagram showing a case where the end points outside the frame of the primary horizontal connection line are connected to the pins of the parts. It is a figure which shows the case where (4) is connected with the diagonal line end point. Next, the calculation formula is shown. X _IN '= X _IN + dx Y _IN ' = Y _IN + dy X _out '= X _out Y _out ' = Y _out The end point of the primary line in the group frame moves in the X-axis direction and the Y-axis direction as the group frame moves. And the value changes. The end points of the primary line outside the group frame do not move because they are connected to the part pins or diagonal lines, and the values do not change.

The cases of the primary vertical connection lines are shown in (c) and (d). (C) corresponds to (A), and (D) corresponds to (B). Therefore, the drawings are omitted and only the equations are shown below. (C) When the primary vertical connection line is connected to the secondary line, or the end point outside the frame is not connected to the pin of the part or the diagonal line end point. X _IN '= X _IN + dx Y _IN ' = Y _IN + dy X _out '= X _out + dx Y _out ' = Y _out (d) The end point outside the frame of the primary vertical connection line is connected to the part pin or diagonal line end point. If you are. X _IN '= X _IN + dx Y _IN ' = Y _IN + dy X _out '= X _out Y _out ' = Y _out (e) Primary diagonal connection line. The movement of the primary diagonal connection line is shown in FIG. X _IN '= X _IN + dx Y _IN ' = Y _IN + dy X _out '= X _out Y _out ' = Y _{out The} primary diagonal connection line is moved along with the group frame. Moves along the Y axis. The end points outside the frame do not move in both the X-axis direction and the Y-axis direction.

(3) Movement rule of secondary line (b) When the primary line is connected to one end point of the secondary horizontal connection line. An example is shown in FIG. 2 connected to the primary line
The end points of the next horizontal connection line are (X2, Y2). The end point after the movement is (X2 ', Y2'). X2 ′ = X2 + dx Y2 ′ = Y2 The end point of the secondary horizontal connection line that is not connected to the primary line is (X3, Y
3). The end point after the movement is set to (X3 ', Y3'). X3 '= X3 Y3' = Y3 The end point of the secondary horizontal connecting line connected to the primary line moves dx in the X-axis direction along which the primary line moves as the group frame moves. The end points of the secondary horizontal connecting line that is not connected to the primary line do not change even if the group frame moves.

(B) In the case of a secondary vertical line connected to the primary line. Since it corresponds to (b), the figure is omitted. The end point of the secondary vertical connection line connected to the primary line is (X2, Y
2). The end point after the movement is (X2 ', Y2'). X2 '= X2 Y2' = Y2 + dy The end point of the secondary vertical connection line that is not connected to the primary line is (X3, Y
3). The end point after the movement is set to (X3 ', Y3'). X3 ′ = X3 Y3 ′ = Y3 The end point of the secondary vertical connection line connected to the primary line changes dy in the Y-axis direction as the primary line moves. The end points of the secondary vertical connection lines that are not connected to the primary line do not change even if the group frame moves.

(C) In the case where the secondary horizontal connecting line is connected to the end point connecting to the primary line, and further to connecting line end points or pins other than the 0th order, the 1st order and the 2nd order. An example is shown in FIG.
FIG. 13A shows the state before the group frame is moved. The secondary horizontal connection line a is connected to the primary vertical connection line b at the end points (X2, Y2), and further connected to the connection lines c other than the 0th order, the 1st order and the 2nd order. The other end points of the secondary horizontal connecting line a are (X3, Y
3). A group frame (dx, d
y) Shows the state after vector movement. The state before the movement is shown by a chain line. The connection line after the movement is shown by a solid line. The end point after the movement of the secondary horizontal connecting line connected to the primary line is (X2 ',
Y2 '), X2' = X2 + dx Y2 '= Y2 Also, a line from (X2, Y2) to (X2', Y2 ') is automatically generated. (D) The primary line is connected to the end points of the secondary vertical connection line, and
When connected to the end points or pins of connection lines other than 0th order, 1st order, and 2nd order. Since it corresponds to (C), omit the figure.
The end point of the secondary vertical connection line connected to the primary line is (X2,
Y2). Further, if the end point after the movement of the secondary vertical connection line is (X2 ', Y2'), then X2 '= X2 Y2' = Y2 + dy Also, the line from (X2, Y2) to (X2 ', Y2') is automatically Occur. By automatically generating the connecting line with the movement of the secondary line, it is possible to prevent the drawing from being divided and to satisfy the rule of the connecting line.

(4) Occurrence of special rubber band line When there is a part that partially overlaps within the group frame, and the pin of the part is connected to the 0th-order figure. This will be described with reference to FIG. FIG. 14A shows a state before the group frame is moved. The part a is a 0th order figure because it is within the group frame. The part b is connected to the part a with pins. Part b is a primary part because only part of it falls within the group frame. FIG. 14B shows the state after moving the group frame. The part a moves together with the group frame, and the part b remains the original position because it is the primary part. The pin coordinates connected to the 0th-order figure of the part b are (X, Y). The pin coordinates on the part b side of the moved part a ′ are (X + dx, Y + dy).
A special rubber band line j from (X, Y) to (X + dy, Y + dy) is automatically generated. FIG. 15 shows another example of generating a special rubber band line. In FIG. 15 (1), part a and part b are adjacent to each other, and part b is surrounded by a group frame. The part a is a primary part and the part b is a zero-order figure. FIG. 15 (2) When the group frame is moved,
Part b moves together and part a remains in its original position.
As shown in the drawings for both parts a and b, there are six pins on each of the right side and the left side. FIG. 15 (3) Special rubber band lines c to h for automatically connecting the pins of the parts on the opposite surfaces of the parts a and b are automatically generated.

Next, the rule of movement other than the group frame is
It will be described with reference to FIG. (1) Parts As shown in FIG. 16 (1), segment areas (shown by dotted lines) are defined around each part. This segment area is regarded as a group frame, and is moved according to the same rule as the group frame. (2) Connection line As shown in FIG. 16 (2), it is considered that a segment area (shown by a dotted line) having a width of 0 is defined around the horizontal connection line and the vertical connection line. This segment area is regarded as a group frame, and movement is performed according to the same rules as the group frame. In the case of a diagonal connection line, set the end point of the diagonal connection line to (X1,
Y1) and (X2, Y2), the segment areas of the diagonal connection lines are (X1, Y1), (X
The area enclosed by the rectangles (2, Y1), (X2, Y2), (X1, Y2) is taken. This segment area is regarded as a group frame. The moving means 11 classifies the connecting lines into horizontal connecting lines, vertical connecting lines, and diagonal connecting lines. As described above, the moving means 11 simplifies the calculation process and improves the processing speed by basing the processing on the horizontal connection line and the vertical connection line.

The magnitudes of the components (x, dy) are shown between (a) and (b) in the figure. FIG. 18 is a flowchart of the moving process in the drawing editing device. The flowchart of FIG. 18 will be described with reference to FIGS. 17 and 19 to 26. The control unit 7 of the drawing editing apparatus creates a parts table (FIG. 19) for storing reference points, segment areas, connection points, and states of parts in the drawing of FIG. For each horizontal connection line, a horizontal connection line table (FIG. 2) that stores the Y coordinate, the X coordinate start point (start point X), the X coordinate end point (end point X), and the state.
0) is created. For each vertical connection line, X coordinate, Y
A vertical connection line table (FIG. 21) that stores the starting point of coordinates (starting point Y), the end point of Y coordinates (ending point Y), and the state is created.
For each diagonal connecting line, start point X, start point Y, end point X,
Diagonal connection line table that stores the end point Y and state (Fig. 22)
To create. Here, the state means that when the group frame is designated and the movement processing is performed, the graphic element is 0th order, 1st
Secondary, secondary, or other (blank in table)
Or which of these is classified. Before the group frame is designated, the states of FIGS. 19 to 22 are all blank.

In FIG. 18, in step S2, the operator designates a moving object. As shown in FIG. 17A, the operator surrounds the graphic element to be moved with a group frame. In step S4, the determination unit 10 obtains a moving target (zero-order figure). The determining means 10 determines that the part B, the horizontal connecting line HC, and the vertical connecting lines VA and VC are 0th-order figures as figures completely included in the group frame. The determining means 10 sets the state of the part B in the parts table shown in FIG. 19 to the 0th order. H of horizontal connection line table (Fig. 20)
The state of C is the 0th order. Vertical connection line table (Fig. 21)
The state of VA is 0th order, and the state of VC is 0th order. Further, the discriminating means 10 discriminates between the primary figure and the secondary figure, and sets the states of the respective tables in FIGS. 19 to 22. In step S6, the moving means 11 creates a special line table. The special line table is shown in FIG.
The special line table is a coordinate value that may generate a special rubber band line. In the case of FIG. 17, it is determined that the part C is the primary part, and the coordinates of the point connected to the horizontal connection line HC that is the 0th-order figure and the connection point (first point) of the part C are registered.

In step S8, the moving means 11
Create a primary horizontal line and secondary vertical line table. Since the primary horizontal line and the secondary vertical line move together, these tables are created at the same time. A primary horizon table is shown in FIG. In the figure and the primary line table, in is the end point information of the connecting lines included in the group frame. At this time, 0: Both sides of the primary connecting line are outside the group frame 1: The first point (starting point) of the primary connecting line is inside the group frame; the second point (end point) of the secondary primary connecting line is the group frame In the inner view of FIG. 1 and the primary line table, out1 is the connection state when the first point is outside the group frame. out2 is the second
This is the connection state when the points are outside the group frame. At this time, 0: When connecting to the secondary line or not connecting to the part pin or diagonal line end point 1: When not connecting to the secondary line and connecting to the part pin or diagonal line end point Primary horizontal line In HA, since the end point (second point) of the connecting line is included inside the group frame, i of the primary horizontal line table
n is 2. At this time, since the first point of the primary horizontal connection line HA is outside the group frame and is connected to the part A, out1 of the primary horizontal line table is 1. Similarly, the information of the primary horizontal line HB is shown in FIG.
It is stored as shown in. This is used to classify the rule of movement of the primary line described above. The secondary vertical line that interlocks with the primary horizontal line is VD. The secondary vertical line table is shown in FIG. In the figure and the secondary line table, stat1 is the connection state of the first point, and stat2 is the second
It is a connection state of points, at this time, 0: No connection with primary line, 1: Connection with primary line but connection line other than 0, 1 and 2 and no connection with parts There is a connection with a line, and there is a connection line other than 0, 1, and secondary, and there is a connection with parts. The secondary vertical line VD has the connection state with the primary line in the connection state at the first point (start point). However, since there is no connection line other than 0, 1, and 2 and connection with parts, as shown in FIG.
tat1 becomes 1. In addition, the connection state of the second point (end point) is not connected to the primary line, so stat2 is 0. This is used for separating the rule of group movement and the case of the secondary line.

In step S10, the moving means 11
Creates a primary vertical line and secondary horizontal line table. The primary vertical line table is shown in FIG. The secondary horizon table is shown in FIG. In step S12, the moving means 11 creates a primary diagonal line table.
The primary diagonal line table is shown in FIG. The primary line table shown in FIG. 24 corresponds to the case where the primary line is classified by the connection state of the end points in the rule of group frame movement described above. FIG. 25 corresponds to the case of the rule of moving the secondary line group frame. In step S14, the moving means 11 deletes the moving target from the display 1. In step S16, it is determined whether or not there is a POINT input, and if there is no input, (N), a mouse cursor is obtained in step S18. In step S20, the coordinates of the primary and secondary special lines linked with the mouse cursor are obtained and set in the rubber band table. The rubber band table is shown in FIG. This is the result of calculation based on the rule of group frame movement described above. In step S22, the dragging echo with respect to the moving object and the line segment echo set in the rubber band table are displayed on the display 1. Returning to step S16, it is determined whether or not there is a POINT input. If there is an input (Y), the process proceeds to step S24. In step S24, the coordinates of the primary, secondary, and special lines interlocked with the point coordinates are obtained and set in the rubber band table. In step S26, the moved figure is registered and displayed again on the display 1. The redisplayed result is shown in FIG. The secondary vertical line VD became a line with a length of 0. The primary part C remains at the original position, and a special rubber band line is generated between the connection point (first point) of the primary part C and the end point of the 0th order horizontal line HC on the end point side. In addition, the primary horizontal line HA became an oblique line. A connecting line is automatically generated between the end points of the secondary horizontal line HE and the connecting line VF.

As described above, in this embodiment, the rule of group frame movement in the drawing editing apparatus and the processing based on the rule have been described. The drawing element is discriminated depending on whether or not it belongs to the group frame, and the group frame is moved based on the movement rule according to the discrimination result. Therefore, it is possible to obtain the drawing editing apparatus in which the connecting lines expand and contract so as to maintain the connectivity with the drawing elements outside the group frame, and the connecting lines are automatically generated as needed. Further, it is possible to obtain the drawing editing device that reflects the connection line rule in the moving process.

Embodiment 2. In this embodiment, the first
The process of adding the second drawing to the drawing will be described. FIG. 27 is a block diagram of the drawing editing apparatus in this embodiment. In the figure, the display 1 to the connecting line dividing means 9 are the same as those in the above-mentioned embodiment and FIG. 12
Is a superimposing means. The superimposing means 12 superimposes the second drawing to be added on the already created first drawing. Reference numeral 13 is an overlap determination means. The overlap determining means 13 determines a graphic element in which the graphic element of the first drawing and the graphic element of the second drawing overlap. Reference numeral 14 is a composite point determination means. When the connecting lines of the first graphic element and the second graphic element overlap each other, the composite point determining means 14 obtains a composite point to be combined into one connecting line. Reference numeral 15 is a dividing means. The dividing means 15 is
When a connection point connecting the connection line of the first drawing and the connection line of the second drawing occurs, the connection line of the first drawing or the second drawing is divided into two connection lines at the connection point. To do. In addition, the connecting point determination means 14 divides the connecting line at the determined combining point. In this embodiment, the synthesis point is obtained in the second drawing to be added. Therefore, the connecting line in the first drawing is divided into two connecting lines at the coordinates of the composite point. But,
The opposite is also acceptable. Further, the dividing means 15 divides the connection line of the first drawing and the connection line of the second drawing at connection points of parts of the respective drawings. The dividing unit 15 divides the figure by the connecting line dividing unit 9 when dividing the figure at the combining point or the connecting point with another connecting line. Reference numeral 16 is a merging unit. The merging means 16 puts together the connecting lines having the inclusive relationship among the connecting lines of the first drawing and the second drawing. In this embodiment, the registration of the connection line of the first drawing is canceled and the connection line of the second drawing is combined into one. However, the opposite is also possible. 17 is a synthesizing means. The synthesizing means 17 uses the synthesis point obtained by the synthesis point determining means 14 as the first
The connecting line of the drawing of FIG. 3 and the connecting line of the second drawing are combined into one connecting line. The synthesizing unit 17 uses the connecting line synthesizing unit 8 when synthesizing the two connecting lines at the synthesizing point. The control unit 18
Connection line composition means 8, connection line division means 9, superposition means 12,
Overlap judging means 13, composite point judging means 14, dividing means 1
5, a merging unit 16 and a synthesizing unit 17.

The additional processing will be described by using an example of superimposing the figure of FIG. 28 (2) on the figure of FIG. 28 (1). The added result is shown in FIG. FIG. 30 is a flowchart of the addition processing of the drawing editing apparatus according to this embodiment. In step S32, the operator specifies an addition target. The addition target is FIG. 28 (2). Step S3
In 4, the addition target is read. FIG. 31 shows a parts table. In the parts table, the parts A in the first drawing to be added (FIG. 28 (1)) are registered. The second drawing parts to be added to the parts table, the reference points of the parts B and C, the segment areas, and the connection points are added. As for the state, the part A remains blank, and the states of the parts B and C are added. Dummy values are entered for the reference points of the parts and the values of the segment areas. Also, X5 *, X6 *, X7 * and Y4 *, Y2 *, Y3 *
Is the value before moving the second drawing to the first drawing.
FIG. 32 is a diagonal connection line table. 33 is a horizontal connection line table, and FIG. 34 is a vertical connection line table. The connection lines in which the states in FIGS. 32 to 34 are blank are the connection lines in the first drawing. The connection line in which the states of FIGS. 32 to 34 are added is the connection line of the second drawing. X2 *, X5 *, X6 * of the connecting lines in the second drawing,
X7 *, Y1 *, Y2 *, Y3 *, and Y4 * are set to values before adding the amount of displacement generated during movement.

In step S36, it is determined whether or not there is a POINT input, and if there is no input (N), step S
At 38, the mouse cursor is obtained. Next, in step S40, the dragging echo of the additional data is displayed. Again, returning to step S36, it is determined whether or not there is a POINT input, and if not, the processing from step S38 onward is performed. If the POINT input is present (Y), the process of step S42 is performed. In step S42, the superimposing means 12 adds the displacement amount to the additional data. Superimposing means 12
The process of 2 performs the following two processes. (1) The displacement amount is added to the additional data. (2) Rearrange the data so that they are in coordinate order. FIG. 35 shows the amount of displacement added to the data of the connection points of the added parts B and C in the parts table. Fig. 36
Is the horizontal connection line table after the change. FIG. 37 shows the changed vertical connection line table. Here, the graphic element to which the displacement amount of the additional data is added is called the T0th order. In the connection line table of FIGS. 36 and 37, a connection line whose state is T0 is added. The data are rearranged so that they are in coordinate order. After that, in the horizontal connection line table and the vertical connection line table, the data is rearranged in the coordinate order. Thereby, the processing can be performed at high speed.

In step S44, the overlap determining means 13 obtains a drawing element overlapping with the T0th order. Drawing elements that overlap the T0th order are called 0th order *. The method by which the overlap determination means 13 obtains overlapping drawing elements is as follows. The drawing or graphic element to be added is determined by the operator by enclosing it in a group frame. Here, the area obtained by adding the displacement amount of movement to the group frame is referred to as an additional box. In the case of a part, since the part area has a segment area, the 0th-order * figure is obtained by determining whether the box in the segment area and the additional box overlap. For connection lines,
Obtained by determining whether the line and the additional box overlap. FIG. 38 is a diagram showing a 0th-order * figure and a combination point.
In FIG. 38 (2), a portion surrounded by a thick dotted line is an additional box. When the additional box is overlaid on the first drawing of FIG. 38 (1), it becomes a portion surrounded by a thick dotted line. The connection lines or parts inside this additional box are 0th order * figures. In step S46, the synthesis point determination means 14 obtains a synthesis point. The composite point is the T0 horizontal line,
A vertical line of order T0 is obtained for the following states. This will be described with reference to FIG. The composite point on the T0th horizontal line is shown in FIG.
As shown in (1), the end point P has no connection to the T0th order graphic element other than the T0th order horizontal line. In the figure,
Since Q is connected to the TO part a, it is not a composite point. An end point (shown in FIG. 39 (2)) R which is a T0-order vertical line and has no connection to a T0-order figure other than the T0-order vertical line.
Is the synthesis point. Since S is connected to the TO part a, it is not a composite point. The combining point indicates a point where combining can occur at the T0th order connecting line and the 0th order * connecting line. In addition, it is the connection lines that are combined. In addition, “combining occurs” means that two connecting lines that are in contact with each other at a combining point are one connecting line. FIG. 38 (2) shows the combining points J, K, L, and M. FIG. 40 shows a combination point table for horizontal connection lines and a combination point table for vertical connection lines.

In step S48, the dividing means 15
Performs division processing between the 0th order * and the T0th order. FIG. 41 shows an example of division by parts. The connection line a is shown in FIG. 41 (1). The additional part b is shown in (2).
In (3), the connection line a is divided into the connection lines e and f at the coordinate position of the connection point of the added part. (4) is a diagram after a part b is added to the connection lines e and f. Thus, when the parts are added to the connecting line, the cutting means 15
Divides the connecting wire into two connecting wires, excluding the pins between parts. Further, the dividing means 15 divides the connecting line a at the point P where another connecting line b is connected to one connecting line a as shown in FIG. 7 by using the connecting line dividing means 9.
The connection line a is divided at the connection point P, and the connection line i and the connection line j
Is divided into Further, the dividing unit 15 divides the 0th-order * connecting line at the combination point determined by the combination point determination unit 14.

FIG. 42 is a view showing the disconnection of the connecting line in the first and second drawings. Next, the above-mentioned three types of processing of the dividing means 15 in FIG. 42 will be described. In FIG. 42, a diagonal line drawn on the connecting line indicates that the connecting line at that portion is divided by parts. Further, a diagonal line attached to characters such as HD or VA indicates that the connection line is divided into other connection lines or divided by the division process. (1) When the connection line is divided by parts The connection line HD in the 0th-order * figure is divided by the part B of the T0th-order figure. The horizontal connection line HD is the horizontal connection line HD2.
And the horizontal connection line HD3. In the 0th * figure, the vertical connection line VA is divided by the part C, and divided into the vertical connection lines VA3 and VA2. The vertical connecting line VD in the T0th figure is
It is divided by part A and divided into vertical connection lines VD3 and VD2. (2) Divided 0th order by combination point * The horizontal graphic connecting line HA is the combination point K (X2, Y1)
And is divided into horizontal connection lines HA2 and HA3. (3) P (X8, Y4) and O (X8, Y) in the divided 0th order * figure by other connecting lines
Since 1) is a connection point with the T0th order figure (VD3, VD2), the horizontal connection line HE and the horizontal connection line HB are divided respectively. Q (X4, Y4) and R (X
5, Y1) is a connection point with the 0th order * diagonal connection line OA, and thus divides the horizontal connection lines HG and HF, respectively.

The results of the processing in steps S44 to S48 are shown in FIGS. 35 and 43 to 45. In each table, * indicates a 0th order * graphic element. T is T
A 0th-order graphic element is shown. The dividing process in FIG. 42 is similar to that in FIG.
How the data changes in the horizontal connection line table No. 3 will be described by taking the horizontal connection line HA as an example. Horizontal connection line H
In A, the Y coordinate is Y1, the starting point X is X1, and the ending point X is X3. The state is *, that is, the 0th-order * figure.
The horizontal connecting line HA is divided into horizontal connecting lines HA2 and HA3 at the composite point K (X2, Y1). Therefore, HA of the horizontal connection line table is deleted. And HA2 (Y
Coordinates, start point X, end point X, state) = (Y1, X1, X2
*) Data is added. In addition, HA3 (Y1, X
2, X3, *) is added. In this way, when the connecting line is divided or divided, the original connecting line is deleted, and the end point information of the divided or divided connecting line is added.

In step S50, the merging means 16
Performs merge processing for the divided lines. FIG. 46 shows the merged drawing. In the figure, the diagonal lines drawn on the connecting lines indicate the merged connecting lines. The merging means 16
The T0th-order connection line and the 0th-order * connection line are compared, and the connection line having an inclusive relation is one T0th-order connection line. In the figure, the horizontal connection line HA3 of the 0th order * figure drawn on the connection line, the T0th order figure, and the horizontal connection line HF2 have an inclusive relation, so HF
Leave only 2. The 0th * horizontal connection line HD2 and the T0th horizontal connection line HG3 leave HG3. HD3 and HH leave HH. Vertical connection lines VA3 and VC leave VC. The vertical connection lines VA2 and VB leave VB.

In step S52, the synthesizing means 17
Will combine the connecting lines at the combining points. In FIG. 47, FIG.
In the drawing of FIG. 6, only connecting lines where synthesis occurs are shown. FIG. 47
In (1), the 0th * horizontal connecting line HC and the T0th horizontal connecting line HG2 are combined at the combining point J (X2, Y4).
The 0th * horizontal connecting line HA2 and the T0th horizontal connecting line HF2 are
It is synthesized at the synthesis point K (X2, Y1). Synthesizing means 17
Uses the connecting line combining means 8 to combine the connecting lines at the combining points J and K. In FIG. 47 (2), the end point coordinates are (X
1, Y4) and horizontal connection line H changed to (X4, Y4)
G2 is shown. In addition, the end point coordinates are (X1, Y1) and (X
5, Y1) shows the modified horizontal connection line HF2. It should be noted that since the synthesizing occurs on the connecting line on the same straight line, the synthesizing does not occur on the vertical connecting line in the case of the figure.

48 and 49 show a horizontal connection line table and a vertical connection line table showing the progress of the processing in steps S50 and S52. The merge processing shown in FIG. 46 describes how the data is changed in the horizontal connection line table FIG. HF2 (Y1, X2, X
5, T) and HA3 (Y1, X2, X3, *) have an inclusive relationship, and are merged into one HF2. for that reason,
HA3 is deleted. HG3 and HD2, HH and HD3 are processed in the same manner. Next, find a set of horizontal connecting lines whose endpoints are the composite points. HA2 and HF2 are synthesized points (X2,
It is synthesized in Y1) and HA2 is deleted. In HF2, the coordinates of the starting point X are changed from X2 to X1. HC and HG2
Is similarly synthesized. The merge process is similarly performed for the vertical connection line table of FIG. As for the vertical connection line, there is no point where merging occurs, so merging processing is not performed.

FIG. 50 shows another example of adding parts.
The additional part f has six pins on each side. Figure 50
The connection lines a to f shown in (1) are divided by the additional part f shown in (2), and the connection lines g to l and m to r shown in (3).
Divided into. The drawing after the part f is added to (4) is shown. In FIG. 51, the connection line i and the connection line j are shown as sections (X2
When overlapping from Y1) to (X3, Y1), the connecting line m1
The process of making a book is shown. In FIG. 51 (1), the connection line i is the 0th order *, and the connection line j is the T0th order connection line. Composite point determination means 1
4 determines that both end points of the connection line j are composite points. (2)
Then, the dividing means 15 connects the connecting line i at the combining point (X2, Y1).
Is divided into connecting lines k and l. In (3), the merging means 16
Compares the end point coordinates of the connection lines, determines that the connection line l is included in the connection line j, and deletes the connection line l. Next, the synthesizing means 17 connects the connecting line k at the synthesizing point (X2, Y1).
And the connection line j are combined to form one connection line m. That is, the end point coordinates of the connection line m are (X1, Y1) and (X4, Y1). The above is the method for realizing the first concept of the connecting line synthesizing means 8 shown in FIG. However, the method of using two overlapping connecting lines as one connecting line is mathematically possible.

As described above, in this embodiment, the end point information of the connecting line which satisfies the connecting line rule can be maintained even when the drawing is added. In addition, when the first drawing overlaps the second drawing, the overlapping graphic element can be deleted and the connecting lines can be connected according to the rule of the connecting line.

Third Embodiment In this embodiment, deletion of graphic elements will be described. FIG. 52 is a block diagram of the drawing editing apparatus in this embodiment. In the figure, the display 1 to the connecting line dividing means 9 are the same as those in FIG. The control unit 20 includes a connection line synthesizing unit 8, a connection line dividing unit 9, a deletion designating unit 21, a deleting unit 22, and an extension synthesizing unit 23. The deletion designating means 21 designates a graphic element to be deleted by enclosing it with a group frame. Alternatively, a connection device or a part to be deleted is designated (picked) with a pointing device. The deleting unit 22 deletes the graphic element designated to be deleted from the display 1, and also deletes the data of the end point coordinates corresponding to the corresponding graphic element. Extension synthesis means 2
53 shows the concept of the processing in FIG. Figure 53 (1)
Then, the part b is connected to the connection line a and the connection line c.
As shown in (2), the coordinates of the pin of the part b are R and S. When the part b is deleted, as shown in (3), the connecting line a having the end point coordinates P and R and the connecting line c having the end point coordinates S and Q remain. The extension synthesizing means 23 extends the connecting line between the sections R and S, and as shown in (4), the end point coordinates P,
The connection line d is Q.

FIG. 54 is a flowchart of the deletion process in the graphic editing device. The flow of processing will be described by taking the case of deleting the part A from the drawing shown in FIG. 55 as an example. FIG. 56 shows tables in which the coordinates of the graphic elements of FIG. 55 are registered. FIG. 56 (1) is a parts table. The value of the segment area is a dummy value. FIG. 56
(2) is a horizontal connection line table, FIG. 56 (3) is a vertical connection line table, and FIG. 56 (4) is an oblique connection line table. In step S62 of FIG. 54, the operator designates a deletion target. That is, part A in the drawing of FIG.
Pick. In step S64, a deletion target is obtained. In this case, since part A has been picked, FIG.
The part A in the parts table shown in (1) is to be deleted. Figure 5 shows the parts table whose state has been deleted and changed.
7 (1). In step S66, it is determined whether the group frame is designated. In this case, since the designation is made by the pointing device 2 and not the group frame, the result is N, and the process of step S68 is performed. In step S68, the horizontal and vertical connection lines associated with the deletion are combined. When part A is deleted, horizontal connecting lines HA and HB
The extension composition of the connecting line is performed between. In the horizontal connection line table of FIG. 57 (2), the states of HA and HB are deleted. Data (Y coordinate, start point X, end point X, state) of the connecting line HE extended by the extension synthesizing unit 23 = (Y2, X
1, X4, addition) are added. There is no change in FIG. 57 (3) vertical connection line table and (4) diagonal connection line table. In step S70, the target data is deleted from the display 1. FIG. 58 shows a drawing in which the part A is deleted. In addition, the processing that becomes Y in step S66 will be described by taking an example of deleting a group frame described later.

Next, an example of deleting the horizontal connecting line HA will be shown. FIG. 59 is a diagram after the horizontal connection line HA is deleted. Tables at this time are shown in FIG. Fig. 60
(2) The state of HA in the horizontal connection line table is changed to deleted. The horizontal connecting lines HA are the vertical connecting lines VA and VB.
Was connected at the connection point (X1, Y2). Since the horizontal connecting line HA is deleted, in order to meet the rule of connecting line,
As shown in FIG. 59, the vertical connection lines VA and VB become one vertical connection line VD. In the vertical connection line table of FIG. 60 (3), the states of VA and VB are changed to deleted, and VD data (X1, Y1, Y3, added) is newly added. There is no change between the parts table (1) in FIG. 60 and the diagonal connection line table (4).

Next, an example in which the vertical connection line VC is deleted is shown. FIG. 61 shows a drawing in which the vertical connection line VC is deleted. As shown in FIG. 55, the vertical connection line VC was connected to the horizontal connection lines HC and HD at the connection points (X5, Y2). To meet the connecting line rule, connecting line HC and connecting line H
D is combined with one connecting line HE by the connecting line combining means 8. Tables at this time are shown in FIG. FIG. 62
(2) In the horizontal connection line table, the states of HC and HD are changed to deleted. New HE data (Y2, X
4, X6, addition) is added. (3) In the VC of the vertical connection point table, the state is changed to deleted. There is no change to the parts table and the diagonal connection line table.

Next, an example of deleting the diagonal connection line OA will be shown. FIG. 63 is a drawing in which the diagonal connection line OA is deleted. The diagonal connecting line OA is connected to the horizontal connecting lines HB and HC at connecting points (X4, Y
It was connected in 2). In order to satisfy the rule of the connecting line, the connecting line synthesizing means 8 synthesizes the horizontal connecting lines HB and HC into one horizontal connecting line HE. Tables at this time,
It shows in FIG. 64 (1) There is no change in the parts table. (2) In the horizontal connection line table, change the states of HB and HC to delete. HE data (Y2, X3, X
5, add) is added. (3) There is no change in the vertical connection line table. (4) In the diagonal connection line table, the state of OA is deleted.

Next, an example of deleting the group frame will be shown. FIG. 65 is a diagram after the group frame is deleted. Only graphic elements within the frame specified by the group frame are deleted. Figure 5
In step S66 of the flowchart shown in FIG.
Whether it is a group frame or not is determined, and since it is a group frame, the result is Y, and the process of step S72 is performed. In step S72, the target data is deleted and a partial cut is performed. Tables at this time are shown in FIG. 66 (1) There is no change in the parts table. (2) In the horizontal connection line table, the state of HC is deleted. In HD, only a part of the connection line is deleted, so that the starting point X is changed from X5 to X8. (3) In the vertical connection line table, VC deletes only a part of the connection line, so the start point Y is Y2 to Y.
It will be changed to 5. (4) The starting point X and the starting point Y of the diagonal connection line table OA are changed from (X4, Y2) to (X7, Y4).

As described above, in this embodiment, the deletion of the graphic element has been described. Even after deleting the graphic element from the drawing, the end point information of the connecting line that satisfies the connecting line rule can be maintained.

Fourth Embodiment This embodiment describes a drawing editing apparatus that automatically recognizes the correspondence between line attributes and connecting lines. Here, the character string entered in the drawing is called an attribute. The line attribute gives the line name of the connecting line, the thickness of the line, the material of the line, and the color of the line. This determines what kind of attributes the target drawing will have according to the type such as sequence, skeleton, electronic circuit, logic circuit, and piping diagram. Multiple types of line attributes can be defined. If there are multiple types of line attributes, define different item numbers. For example, the item number for the line name is 4, the item number corresponding to the thickness of the line is 5, the item number for the material of the line is 6, and the item number for the color of the line is 7. FIG. 67 is a block diagram of the drawing editing apparatus in this embodiment.
The display 1 to the external storage device 6 are the same as those in FIG. The control unit 25 includes an area setting unit 26, an editing unit 27,
It comprises a character string determination means 28 and a list creation means 29. The area setting means 26 sets information necessary for determining whether or not the character string has a line attribute. The editing means 27 edits the character string. The character string determination means 28 determines whether the line attribute and the connecting line correspond to each other. The list creating means 29 uses the connecting line and the line attribute determined by the character string determining means 28 to have a correspondence relationship from-to-connect the connecting line.
Create a list.

The area setting means 26 sets the area table shown in FIG. 68 (1). The area setting unit 26 registers the judgment areas (xmin, ymin, xmax, ymax) for horizontal lines and vertical lines and the text orientation for each item number in the area table. As shown in (2), there are four text directions, and 0 to 3 are associated with each direction. Areas xmin, ymin, set in the area table
The meanings of xmax and ymax will be described using (3). For example, assume that the line attribute D7 is entered in the drawing. It is assumed that the correspondence between the line attribute D7 and the connecting line is checked. Attribute reference point of D7 (Which position of the attribute is the attribute reference point
Xm in the positive direction of the X axis
ax, xmin in the negative direction, ymax in the Y-axis positive direction,
The character string determination unit 28 creates a box (determination region) on the drawing with a size of ymin in the negative direction. In the figure, boxes are indicated by dotted lines. The character string determination unit 28 determines that the line attribute D7 has a correspondence relationship with this connection line if the box and the connection line partially overlap. However, the line attribute D
If the connection line is separated from 7 and the box and the connection line do not overlap, it is determined that there is no connection line corresponding to the line attribute D7.

FIG. 69 is an example in which attributes are entered in the drawing. In the figure, character strings in which HC, VD, ... Are enclosed by squares are identifiers for identifying the connecting lines, respectively, and are not displayed in the drawing. A and B surrounded by a square
C is an identifier of the part and is not displayed on the drawing. Character strings that are not enclosed in squares are attributes. The line attributes are D7 and B8. 70 and 71, the flow of processing for determining the correspondence between line attributes and connecting lines and creating a from-to-list will be described with reference to the drawing of FIG. 69 as an example. In steps S82 to S92, the character string determination means 28
However, the list creation means 29 processes step S94. The attribute table shown in FIG. 72 is created in advance before executing the command to create the from-tour list. The attribute table is registered for all the attributes described in the drawing shown in FIG. In the figure, item numbers, pin numbers, reference points, segment areas, text orientations, and item values are registered for the attributes corresponding to parts A, B, and C, respectively. For the part with the identifier A, item number 2 (representing the part name), ... Item value 3-TBL1R is registered. Item number 3 (representing the pin of the part), pin number 1, ... Item value 5 is registered for the part A. An identifier is temporarily attached to a line attribute having no corresponding part and registered in the attribute table. At this point, the line attribute and the connecting line are not associated with each other. Item number 4 (representing the line name) for the identifier Z1 ...
The item value D7 is registered. Here, the relationship between the item number and the item value is as follows. For example, when the user wants to write the line attribute in the drawing, the command for inputting the line attribute is executed. The operator specifies the item number (4) and inputs the line attribute (D7). 4 is the item number, D
7 is registered as an item value in the attribute table. Also, the direction of the text depends on the input D7 direction.
Any value from 0 to 3 (see FIG. 68 (2)) is registered in the attribute table.

The flowchart of FIG. 70, step S82.
In, the vertical connection lines are divided into connection groups. The connection group is shown in FIG. 73 (1). Since VA to VD are not connected to each other, they all belong to different groups. In step S84, the horizontal connection line is added to the connection group. FIG. 73 (2) shows a connection group. Grouping is performed by determining the connection between the connecting lines from the end point information of each connecting line. In Group 1,
Horizontal connection lines HA and HB are added to the vertical connection line VA. By adding the horizontal connecting line HA to the group 1, VB of the group 2 is also merged into the group 1 from the end point information. In this way, the vertical connection lines and the horizontal connection lines are grouped with reference to the end point information of the connection lines. In step S86, the diagonal connection line is added to the connection group. In FIG. 69, since there is no diagonal connection line, this process is skipped. However, the diagonal connection line is also determined to which group it belongs from the end point information. Step S88
In, add the connection points of the parts to the connection group.
FIG. 73 (3) shows a connection group. A connection point of a part consists of a part identifier and a connection point number. The part identifiers are A, B, and C in FIG. 69. Taking the part A in FIG. 69 as an example, the connection point number is 1 on the left side (first point) and 2 on the right side (second point). Further, taking the part B as an example, the lower pin (first point) is 2, and the upper pin (second point) is 1. It can be seen from FIG. 69 that the part connected to the group 1 is the first point of the part C.
Information of C2 is added to the group 1 of (3).

In step S90, the line attribute of the vertical connecting line is obtained. The process of obtaining the line attribute of the vertical connection line will be described with reference to the flowchart of FIG. In FIG. 71, step S96, data is read from the attribute table. Refer to the attribute table of FIG. Step S98
In, it is determined whether or not the item number is the target of the line attribute. If it is not the item number that is the target of the line attribute,
The result is N, and the process returns to step S96. If the item number is the target of the line attribute, the result is Y, and the process of step S100 is performed. In step S100, it is determined whether the text orientation is the orientation of the vertical connection line. In the case of N, the process returns to step S96. For example, for the data of the identifier Z1 in the attribute table, the item number is 4 and the item number is the target of the line attribute, but the text direction is 0 and is not the target direction of the vertical connection line. Become. For the data of the identifier Z2, the item number 4 is the item number targeted for the line attribute. Since the direction of the text is 1, which is the target of the vertical connection line, the result is Y, and the process proceeds to step S102. In step S102, a box is obtained from the reference point of the attribute. The reference point of the attribute is registered in the attribute table. Further, the box is created with the value registered in the area table shown in FIG. 68 (1). The dotted line area shown in FIG. 68 (3) is a box. In step S104, it is determined whether or not the box and the vertical connection line partially overlap. If they do not overlap, N is determined, and the process returns to step S96. If they overlap, the result is Y, and the process of step S106 is performed. In step S106, the line attribute is added to the connection group. FIG. 74 (4) shows a connection group. The line attribute B8 indicates the vertical connection line V by the character string determination means 28.
It is determined that the line attribute corresponds to C, and B is assigned to group 3.
8 is added. The line attribute D7 is determined to be a line attribute corresponding to the horizontal connection line HD by the character string determination means 28, and is added to the group 4. The above is the process of obtaining the line attribute of the vertical connection line.

Returning to FIG. 70, in step S92,
Find the line attribute of a horizontal connection line. The method of obtaining the line attribute of the horizontal connecting line is the same as the method of obtaining the line attribute of the vertical connecting line, and therefore description thereof will be omitted. In step S94, the list creating means 29 outputs a from-to-list. The from tourist list is shown in FIG. 74 (5). The From Tourist is a list of line attributes of connecting lines that connect parts. It is created by referring to the attribute table from the connection line group of FIG. 74 (4). This will be described by taking the group 3 of FIG. 74 (4) as an example. A vertical connection line VC, a part C, a part B, and a line attribute B8 are registered in the group 3. The part name is known from the item value 43TBL1 of the part C by referring to the attribute table (FIG. 72). Further, since the connection point number (called a pin number in the attribute table) of the part C is 1, the item value 5 is known by looking at the identifier C and the pin number 1 in the attribute table. 5
Is the terminal name of the part C on the drawing. Similarly, for part B2, part name 3-TBL1L and terminal name 2
To get Since the line attribute registered in the group 3 is B8, the line attribute is B8. In this way, the from-tour list shown in FIG. 74 (5) is created. If only the correspondence between the line attribute and the connecting line is determined, the list creating means 29 for creating the from-to list may be omitted.

As described above, in this embodiment, the area table in which the judgment areas for judging the correspondence between the line attributes and the connecting lines are registered is provided. If there is a connecting line in the line attribute determination area, it is determined that there is a correspondence between the line attribute and the connecting line. If there is no connecting line in the line attribute determination area, there is no correspondence between the line attribute and the connecting line. Thus, when a person looks at a drawing, it is possible to obtain a drawing editing device that can determine the correspondence between a line attribute and a connection line based on the same criteria that a character string written near the connection line is determined to be the line attribute. You can Further, it is possible to obtain a drawing editing apparatus that automatically creates a from-tour list from the correspondence between line attributes and connecting lines. Although an electric circuit diagram has been described as an example in this specification, a drawing intended for the drawing editing apparatus may be a sequence, a skeleton, an electronic circuit, a logic circuit, a piping diagram, or any other drawing.
