Here, the CAD information relating to the symbols, line segments, and character strings is stored in the graphic data storage means 5, and how it is stored will be specifically described with reference to FIG. I do. In FIG. 4, as for the CAD information of the symbol, the symbol handled by the target graphic is n.
If there is one {0 (n1-1)}, the key numbers of the n1 symbols are managed in the table s1.

Information such as the type of each symbol, the display position on the display device 4, the display color, the display rotation direction angle, etc. is stored in the table s11 for the symbol 1, for example. It can be traced by calling the key number 0, and the reference is updated.

From symbol 2 onward, the individual symbols between the symbols (n1) are also displayed in the same table as the table s11 corresponding to the symbol 1, the respective symbol types, the display positions on the display device 4, and the display colors. And information such as the display rotation angle and the like.

Next, as for the CAD information of the line segment, similarly to the CAD information of the symbol, if there are n2 line segments {0 to (n2-1)} handled by the target graphic, the n
The key numbers of the two lines are managed in the table L1.
In the table L11 corresponding to the symbol table s11, the point having the start point and the end point of the line segment is different from the case of the symbol.

As for the CAD information of the character string, similarly to the CAD information of the symbol, if there are n3 {0 (n3-1)} character strings handled in the target graphic, the n3
The key numbers of the character strings for each item are managed in the table M1.
Then, the character string is treated as being composed of the character string frame portion and the character code described therein, and in the table M11 corresponding to the symbol table s11, the character string frame center position, the character string frame rotation Direction angle, character string code,
It differs from symbols in that it has a character font size.

Next, group data relating to groups of symbols, line segments, and character strings are stored in the group data storage means 6.
, But how it is held will be specifically described with reference to FIG. In FIG. 5, for the group data, the elements (symbols, line segments, character strings) of all the groups handled in the target drawing are n7 ｛0
~ (N7-1)}, the key numbers of the n7 group elements are managed in the table G1.

Each group element is composed of a symbol, a line segment,
What kind of string, symbol, line segment, what is the key number in the string, whether it is the root in the group tree structure, what is the parent group element, what is the brother group element, Information such as what is the group element of the first child is, for example, waiting for the group element 1 in the table G11, which can be traced by calling the key number 0 of the group element 1 and referring to the contents of the table G11. Be updated.

Here, the root represents the element at the top of the tree structure. In the example of FIG. 3, the symbol a corresponds to the root. The parent is an element that is in a tree structure and is located vertically from the one-stage root and is linked to itself. In the example of FIG. 3, the line segment b1, the line segment b2, and the character string c
1, the parent of the character string c2 corresponds to the symbol a, and the character string d

In the tree structure, the element is located in the vertical direction opposite to the one-step root and is linked to the element.

In the example of FIG. 3, the first child of the symbol a is a line segment b
1, the character string c1, and the first child of the line segment b2 is the character string d1
Is equivalent to The younger brother has a tree structure and is equal to itself in the horizontal direction, and represents a linked element. In the example of FIG.
The younger brother of line segment b1 corresponds to line segment b2, the younger brother of character string c1 corresponds to character string c2, and the younger brother of character string d1 corresponds to character string d2.

With respect to the individual group elements 2 to n7 from the group element 2 to the group element n7, the respective symbols, line segments, character string types, and the like are stored in the same table as the table G11 corresponding to the group element 1. parent,
He has information on his younger brother and firstborn child.

Here, the area inside / outside judgment flag f and the decision judgment flag e in the table 11 are used only when the self is the root. Also, the key number of the parent group element.
Is -1 at the root and the key number of the younger brother group element. Has his own key no. When he is the youngest brother, he returns to his original key No. Becomes Further, the key No. Is -2 if there is no first child.

Next, the relationship between the tables G1 and G11 and FIG. 3 is specifically shown in FIG. In FIG. 6, when a case where the group element key number 5 (a0) is selected is considered, a1
From this group element key number 5 is the character string key No. 2
(Character string d1), it is determined from a2 that the parent group element is group element key number 2,
From a3, it is found that the younger group element is group element key number 6, and from a4, it is found that there is no birth group element.

Here, the newly appearing group element key number 2 (parent) and group element key number 6 (brother) are also recursively changed.
Reaches the root for the parent (a2).

If there is one or more younger brothers, there is no firstborn child until they return to themselves in a round (obtain their own group element key number in the a3 column of the younger brother) (at -a4-
2).

Clearly by the method described here, FIG.
In the example, the group element key number 5 is selected so that the group element key number 0 to the group element key number 6 are selected.
Is determined as all the elements of one group to which the group element key number 5 belongs, and the tree structure is clarified.

Therefore, in general, by this method,
If you select one of the elements that make up the group,
All elements in one group to which the element belongs can be traced, and the tree structure becomes clear.

Therefore, by using the data structure of the group defined here, various graphic data (symbols, line segments, character strings) which are the elements constituting the group can be obtained.
If a figure on the screen display of the display device 4 corresponding to any one of the above is selected by the pointing device 3 as an input device, the group attribute structure processing means 8 follows the link information in the data structure of the group. Becomes possible.
This makes it possible to identify this group from a plurality of group groups.

Next, a first embodiment of the present invention will be described. FIG. 7 shows a display device 4 according to the first embodiment of the present invention.
FIG. 5 is an explanatory diagram showing an example of a display screen for displaying a screen. In the first embodiment, the display of groups S1 to S4 composed of symbols, line segments, and character strings is displayed in different colors on the screen of the display device 4 for each group. 4
A plurality of groups that are mixed can be easily identified on one screen.

The group attribute structure processing means 8 associates each group with which symbol, line segment, and character string based on the group data stored in the group data storage means 6. The graphic display processing means 7 performs color display on the display device 4 for each group associated by the group attribute structure processing means 8.

That is, the group is identified by executing the group attribute structure processing means 14. The group attribute structure processing means 8 associates each of the plurality of groups with various graphic data (symbols, character strings, and line segments), and performs graphic display processing on each of the groups. By means 7, the color is displayed on the display device 4 for each group.

More specifically, as shown in FIG. 7, four groups S1, S2, S3, and S4 surrounded by broken lines are displayed on the screen of the display device 4 in different colors, respectively. It is easy to identify a plurality of mixed groups.

Next, a second embodiment of the present invention will be described. FIG. 8 is an explanatory diagram illustrating an example of a display screen on the display device 4 according to the second embodiment of the present invention. In the second embodiment, graphic data (symbols, line segments, character strings)
Is specified by directly selecting one of an arbitrary symbol, line segment, and character string in the group to be specified by the input device.

The group attribute structure processing means 8 is stored in the group data storage means 6 when any of the symbols, line segments, and character strings constituting the group is specified according to a group designation command from the input device. Specify the entire group based on the group data. And
The graphic display processing means 7 identifies and displays the entire group specified by the group attribute structure processing means 8 on the display device 4.

That is, by directly selecting one of a symbol, a line segment, and a character string by the pointing device 3 as an input device, the group attribute structure processing means 8 refers to the data structure of the group. Then, the group data is traced based on one selected various graphic data. For example, when the user wants to select the group S1 from the four groups S1, S2, S3, and S4 surrounded by broken lines shown in FIG. 7, as shown in FIG. 8, the symbols, line segments, and character strings in the group S1 are selected. Select one of the components. For example, by directly selecting the character string c11 or the line segment b12 with the pointing device 3, the group data can be traced based on the character string c11 or the line segment b12, and the entire group S1 can be designated.

Here, when various figures are close to each other, whether or not they belong to a certain group is determined by the figure display processing means 7.
And the area inside / outside determination processing means 9. The determination method will be specifically described with reference to FIG. [1] First, as shown in FIG.
Sets a grid-like mesh for the target drawing inside the computer. As shown in FIG. 9B, the mesh is set in a grid shape and the size is proportional to the display scale on the display device 4 and the vertical length h and the horizontal length w are respectively multiplied. Use something. [2] Next, as shown in FIG. 9C, when the two-dimensional coordinates (XP, YP) of the point P are designated by the pointing device, the coordinates are obtained. [3] Next, it is determined from XP / wα and YP / hα which of the meshes in the grid-like mesh group of the target drawing set in the above [1] the coordinates (XP, YP) are. As shown in FIG. 9D, it is found that the point P selected by the pointing device is within the meshes (a, b, c, d) in the mesh group divided into a lattice. [4] Then, by comparing the coordinate values of the four corner areas of the mesh (a, b, c, d) with the data of the CAD information relating to the positions of all symbols, line segments, and character strings, Find the key numbers of all symbols, line segments, and character strings caught on the mesh. (1) First, if the determined key number is one, the figure is determined. For example, the line segment L1 is determined as shown in FIG. (2) On the other hand, as shown in FIG. 9 (f), if the determined key number is 0, the figure is not determined. (3) Further, if there are a plurality of obtained key numbers, the first graphic 1 in the order of symbol → character string → line segment, and further in the ascending order of the respective key numbers in the symbol, character string and line segment. Only the number is determined. If the figure you want to select is not fixed, select a point closer to the figure you want to select or a part that you want to select that is not relatively adjacent to the multi-figure by using the pointing device again to determine the figure you want to select. Is done. That is, in the example shown in FIG. (4) When the point P0 is selected by the pointing device, the younger figure among the line segments L1 and L2 is determined in ascending key number order. (5) When the point P1 is selected by the pointing device, the line segment L1 is determined. (6) When the point P2 is selected by the pointing device, the line segment L2 is determined. (7) When the point P3 is selected by the pointing device, the symbol S1 is determined (CAD related to the position of the symbol).
For the information, the center position is handled, and meshes (e, f, g,
When h) is selected with a pointing device, the symbol S
1 is determined). (8) When the point P4 is selected by the pointing device, the line segment L2 is determined.

According to such a determination method, even if various figures are close to each other, if α is adjusted in advance in the portion [1] and the mesh is cut finely enough, the figure to be selected by the pointing device can be selected. It can be determined from the inside, and furthermore, it becomes possible to handle the grouping of the determined figures by the method described in FIG.

Next, a third embodiment of the present invention will be described. FIG. 10 is an explanatory diagram illustrating an example of a display screen on the display device 4 according to the third embodiment of the present invention. This third
In the embodiment, when two types of groups are merged,
An arbitrary symbol, line segment, or character string in each group element is directly selected one by one by the input device.

The group attribute structure processing means 8 receives a group merge command from the input device, and when any of the symbols, line segments, and character strings constituting each group to be merged is designated, the group data Each group is identified based on the group data stored in the storage means 6, and the respective groups are designated together. And
The graphic display processing means 7 displays the group designated and merged by the group attribute structure processing means 8 on the display device 4.

That is, when it is desired to combine two types of groups, the pointing device 3 directly selects any one of the symbols, line segments, and character strings in each group element. Thus, the group attribute structure processing means 8 refers to the data structure of each group and traces the group data based on each of the selected various graphic data.

For example, in FIG. 10, when the group S1 and the group S4 are merged, first, in order to designate the group S1, any one of the components of the symbol, line segment, and character string in the group S1, for example, the character Column c11 or line segment b
12 is directly selected by the pointing device 3. Next, similarly, any one of the components of the symbol, the symbol, and the character string in the group S4, for example, the line segment b41 or the character string c41 is directly selected by the pointing device 3. Through these processes, the two specified groups are merged.

Next, a fourth embodiment of the present invention will be described. FIG. 11 is an explanatory diagram illustrating an example of a display screen on the display device 4 according to the fourth embodiment of the present invention. This fourth
In the present embodiment, on the screen of the display device 4 on which a plurality of groups are displayed in a mixed manner, a group whose group can be confirmed is displayed in the same color as the background color of the display screen of the display device 4. In this way, the group that has been confirmed and the group that has not been confirmed are determined.

The group attribute structure processing means 8 stores the group data in the group data storage means 6 when there is a group determination command from the input device and any one of the symbols, line segments and character strings constituting the group is designated. Specify the entire group based on the stored group data. Then, the graphic display processing means 7 displays the entire group specified by the group attribute structure processing means 8 on the display device 4 in the same color as the background screen.

That is, on the screen of the display device 4 on which a plurality of groups are displayed in a mixed manner, the ones for which grouping has been confirmed are displayed in the same color as the background screen of the display device 4. This makes it easy to determine whether the grouping has been confirmed or not.

The group attribute structure processing means 8 identifies to which group each symbol, line segment and character string belongs based on the group data stored in the group data storage means 6. Thereafter, it is determined whether the image is determined or not, using the determination flag e set for each group. If the grouping is confirmed, a flag is set.

Only the group for which the flag is settled is displayed in the same color as the screen background color of the display device 4 by the graphic display processing means 7 so that the operator substantially disappears and cannot see it. This makes it easier to determine an undetermined group that needs to be checked.

Specifically, in FIG. 11, if it is desired to determine the group S2, one of the components of the symbol, line segment, and character string in the group S2 to be determined, for example, the character string c21 or the line segment b23 Is directly selected by the pointing device 3 so that the designated group S2
Becomes the same color as the background screen of the display device 4, and the group S2 is determined. In addition to the same color as the background color, it is also possible to use a bold line emphasis color or the like for the confirmed group.

Next, a fifth embodiment of the present invention will be described. FIG. 12 is an explanatory diagram illustrating an example of a display screen on the display device 4 according to the fifth embodiment of the present invention. This fifth
In the embodiment of the present invention, when deleting a symbol, a line segment, a character string, or a group including these, the symbol, line segment, character string, or group to be deleted is individually specified,
Alternatively, an operator designates a target area by an input device, and designates and deletes symbols, line segments, character strings, and groups included in the area at once.

When the area is designated by the input device on the display screen of the display device 4,
The group, the symbol, the line segment, and the character string included in the area are determined. When there is a delete command from the input device and a region is designated by the inside / outside process determination unit 9, the figure display processing unit 7 displays the group, symbol, line segment, and character string displayed in the region. Erase from device.

In this case, the symbol, line segment, character string, and group to be deleted may be individually specified,
They may be specified collectively. When specifying an area in a lump, delete the part enclosed by the area at a lump, and also all (or part of) a symbol, line segment, character string, or group that touches the area boundary May be a deletion target.

That is, when deleting a symbol, a line segment, a character string, and a group consisting of these, the symbol, line segment, character string, and group to be deleted are individually specified or included in the deletion target area. Alternatively, the user selects whether to specify all (or part of) the symbols, line segments, character strings, and groups that touch the area boundary line.

In the case of individual deletion, by directly selecting the symbol, line segment, character string and group to be deleted by the pointing device 3, various graphic data (symbol, line segment, character string) are displayed by the graphic display processing means 7. The symbol, line segment, character string, and group selected from the CAD information and groove data information held as ()) are deleted, and are deleted from the screen of the CRT display screen 4.

On the other hand, in the case of area designation deletion, first, the operator directly designates the coordinates of two vertexes in the diagonal direction of the rectangle with the pointing device 3 in order to designate the area. Subsequently, the processing of the area inside / outside determination processing means 9 is performed. In this process, based on the coordinates of the four vertices of the specified area,
Automatically checks whether all symbols, line segments, character strings, and groups are included in the rectangle specified by the operator (or caught by the border), and is included in the rectangle (or caught by the border) Is
The area inside / outside determination flag f, which is added to each of the symbols, line segments, character strings, and groups, rises. The area inside / outside determination flag f for this group is shown in FIG.

The graphic display processing means 7 determines, based on the area inside / outside determination flag f, whether symbols, line segments, character strings, and group graphic elements on which this flag is set may be collectively deleted. The operator is notified, whereby the symbols, line segments, character strings, and groups included in the rectangle (or caught by the boundary) are deleted collectively without being individually deleted.

As described above, when a symbol, a line segment, a character string, and a group are individually designated and deleted, the graphic to be designated is directly selected by the pointing device 3. In the case of area designation deletion, in FIG. 12, the operator designates the point A and the point C (or the point B and the point D) by using the pointing device 3 to designate the area displayed by the rectangle 10, and The symbols, line segments, character strings, and groups in the area (or caught on the area boundary) are collectively deleted. This FIG.
In the example of the line segment b51, b52, b53 in the square 10,

Next, a sixth embodiment of the present invention will be described. FIG. 13 is an explanatory diagram illustrating an example of a display screen on the display device 4 according to the sixth embodiment of the present invention. This sixth
In the embodiment, when a symbol or a character string is to be added or moved, one of the line segments having the desired direction is directly selected by the input device with respect to the direction at the addition destination or the movement destination, and the line is selected. A symbol or a character string is added or moved according to the minute direction.

The graphic display processing means 7 receives a command to add or move a symbol or a character string from the input device, and designates a line segment having a direction desired to match the direction at the addition or movement destination by the input device. At this time, a symbol or a character string is added or moved in accordance with the direction of the line segment.

For example, in FIG. 13, a case where it is desired to move the symbol a0 to the location a2 will be described. In this case, the pointing device 3 directly selects the line segment b having the desired direction with respect to the direction at the movement destination a2. As a result, the information θ regarding the direction of the line segment b is transmitted to the graphic display processing means 7, and the direction of the symbol a0 stored in the graphic data storage means 5 is updated to the direction θ of the line segment b. As a result, the direction of the symbol a0 can be automatically adjusted to match the destination a2.
