[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic configuration of a CAD system in which a leader line creating apparatus with a note according to one embodiment of the present invention is incorporated. In the CAD system of the present embodiment, when writing a leader line with a note on drawing data, a note character is input, and the starting point of the leader line, a node, and the direction of bending from the node are indicated on the drawing. When the direction instruction is stopped, from the start point, to the leader line to the node, annotated leader line data with the annotation is generated, and when the direction instruction is performed, from the start point, Annotated leader line data obtained by folding at a node and attaching the annotation to the leader line in the bent leader direction can be generated and written on the displayed and stored drawing data.

The CAD system shown in FIG. 1 includes a CAD processing section 1, an input device 2, a display 3, an output device 4, and a storage device 5. CAD processing unit 1 includes a CPU
(Central processing unit) (not shown), and executes CAD processing including annotated leader line creation processing.
The input device 2 includes an operation input device such as a keyboard and a pointing device such as a mouse, and inputs operation input information by an operator and other external information necessary for CAD processing to the CAD processing unit 1. Display 3 uses CA
Necessary information such as processed image information by the D processing unit 1 and information related to input by the input device 2 is displayed. Output device 4
Includes a plotter or a printer, etc.
Is output as a hard copy. The storage device 5 is composed of, for example, a disk device such as a hard disk device and operates in association with the CAD processing unit 1 to store data such as image information before, after, and during processing as needed. .

In this case, the CAD processing unit 1
In addition to the configuration for executing the D process, the display control unit 11, the command input unit 12, the note input unit 13, the start point indicating unit 14, the node, and the like for executing the annotation leader line creation process according to the embodiment of the present invention. It includes an instruction unit 15, a direction instruction unit 16, a discrimination processing unit 17, a leader line generation unit 18, a memory 19, and a write / rewrite control unit 20.

The display control section 11 controls the display on the display 3. Under the control of the display control unit 11, drawing data and the like are displayed on the screen of the display 3. The command input unit 12 performs a process for allowing the operator to input a command including a command for writing a leader line with a note by interactive operation with the screen of the display 3, for example. For this reason, the command input unit 12 controls the display control unit 11 as needed.

The annotation input section 13 functions at least when the annotation-added leader line entry command is input by the command input section 12, and for example, via the input device 2,
Processing for inputting a note to be attached to the leader line by the operator is performed. Therefore, the note input unit 13 also controls the display control unit 11 as necessary. Start point indicator 14
Function at least when the command to enter the annotated leader line is input by the command input unit 12,
For example, by performing an interactive operation with the screen of the display 3, a process for instructing the start point of the annotated leader line on the drawing by the operator is performed. Therefore, the start point instruction unit 14 also controls the display control unit 11 as necessary.

The node designating section 15 functions when the starting point is designated by the starting point designating section 14. For example, by interactive operation with the screen of the display 3, the node of the annotated leader line on the drawing is designated by the operator. A process for instructing is performed. At this time, in consideration of the fact that a straight leader line, that is, a leader line that is not bent in the middle is formed by an instruction to this node, and to facilitate the instruction of the node, a start point and a node as shown in FIG. A cursor consisting of an auxiliary line corresponding to the leader line and a character frame indicating the position of the note character is displayed between the pointer and the designated point. Therefore, the node instruction unit 15 also controls the display control unit 11 as necessary.

The direction indicating section 16 functions when the node is indicated by the node indicating section 15, and, for example, by interactive operation with the screen of the display 3, a leader line with a note is drawn from the node on the drawing. A process is performed to allow the operator to specify the drawing direction. This direction instruction is performed, for example, by designating the placement point of the annotation character after the drawing. At this time, in order to easily indicate the pull-out direction, FIG.
A cursor consisting of an auxiliary line corresponding to a leader line from a node and a character frame indicating the position of a note character is displayed. Therefore, the direction instruction unit 16 also controls the display control unit 11 as necessary.

The determination processing unit 17 determines whether the direction of the drawing from the node is specified by the direction specifying unit 16 or whether the direction of the drawing direction by the direction specifying unit 16 from the node is stopped. The leader line generation unit 18 responds to the determination result of the determination processing unit 17 and, when the direction instruction is stopped, from the start point specified by the start point specification unit 14 to the node specified by the node specification unit 15. When a leader line is generated with annotated leader line data to which a note input by the note input unit 13 is attached, and the direction instruction is performed,
From the start point designated by the start point designation unit 14, the node designation unit 15
Is generated at the node pointed by (1), and annotated leader line data in which the note input by the note input section 13 is attached to the leader line in the bending lead direction specified by the direction indicating section 16 is generated.

The memory 19 stores information including CAD drawing data to be displayed by the display control unit 11. The contents stored in the memory 19 are transferred to the storage device 5 as needed. The memory 19 may share a memory used in normal CAD processing in the CAD processing unit 1. The writing / rewriting control unit 20 writes the annotated leader line data generated by the leader line generation unit 18 on the drawing data displayed on the display 3 and stored in the memory 19.

Next, the operation related to the creation of the annotated leader line in the CAD system having such a configuration will be described in detail with reference to the flowchart shown in FIG. The process shown in FIG. 2 is started as an interrupt process by a command input during normal drawing or editing operation in the CAD system.

First, the command input unit 1 of the CAD processing unit 1
2, the drawing of the leader line is selected (step S
1) When a leader line with a note is selected as the type of the leader line (step S2), the system is set to a leader line creation mode with a note (step S3). When the mode is set to the annotation-added leader line creation mode, the operator inputs annotation characters to be attached to the leader line by the annotation input unit 13 of the CAD processing unit 1 (step S4). The input of the note character string by the note input unit 13 in step S4 is performed by requesting the input of the note character by the operator through the screen of the display 3, and the operator performing the character string input operation or the like in response thereto.

When a note character is input in step S4,
The starting point designating unit 14 of the CAD processing unit 1 gives an instruction by the operator of the starting point on the drawing from which the annotation-added leader line should be drawn (step S5). The instruction of the start point by the start point instructing section 14 is requested by an operator's input via the screen of the display 3 and the operator performs an instruction operation using a cursor on the screen in response thereto.

When the start point is specified in step S5, CA
The operator of the node of the leader line drawn from the starting point is specified by the node specifying unit 15 of the D processing unit 1 (step S6). The node pointed in step S6 is literally a bending point of the leader line in the case of a one-point broken leader line, but is the end point of the leader line in the case of a straight leader line. The instruction of the node by the node instruction unit 15 in step S6 is also performed by requesting an input by the operator via the screen of the display 3 and performing an instruction operation or the like using a cursor on the screen in response thereto. In order to facilitate the pointing operation, the cursor in the case of the node designation has an auxiliary line corresponding to the leader line between the start point and the designated point of the node as shown in FIG. The annotation is formed by a character frame indicating the character position.

When a node is designated in step S6, CA
The direction instructing unit 16 of the D processing unit 1 gives an instruction of an extraction direction of a leader line drawn from the node by the operator (step S7). The leader direction specified in step S7 is the direction of the leader line in which the annotation character is arranged in the case of the one-point broken leader line. This direction indication is
For example, it is directly performed by designating the arrangement point of the annotation character after the drawing. The cursor in this direction indication is
In order to easily specify the drawing direction, an auxiliary line corresponding to a drawing line from a node as shown in FIG. 9 and a cursor including a character frame indicating a note character position are displayed. In this step S7, it is also possible to stop the instruction of the drawing direction without indicating the drawing direction (as will be described later, if the instruction of the drawing direction is stopped in step S7, the lead line becomes 1). It is not a broken line but a straight line).

Following the processing in step S7, step S7
The determination processing unit 17 determines whether the direction instruction has been performed or the direction instruction has been stopped (step S8). If the direction instruction has been stopped, the leader line generation unit 18 generates a straight leader line (step S8). Step S9). That is, in this case, in step S9, the leader line generation unit 18
From the start point designated by the start point designation unit 14, the node designation unit 15
Annotated leader line data in which the annotation input by the annotation input unit 13 is added to the leader line up to the node indicated by (1) is generated. When the leader line data with annotation is generated in step S9, the writing / rewriting control unit 20 writes the leader line data with annotation on the drawing data displayed on the display 3 and stored in the memory 19 ( Step S10) and proceed to the next process.

If it is determined in step S8 that a direction instruction has been made in step S7, the leader line generation unit 18 sets 1
A point break leader line is generated (step S11). That is, in this case, in step S11, the leader line generation unit 18 starts from the start point designated by the start point designation unit 14.
Annotated leader line data is generated in which a leader line bent at the node designated by the node designation unit 15 and extending in the direction designated by the direction designation unit 16 is annotated with the note input by the note input unit 13. . In step S11, even when the annotated leader line data is generated, the writing / rewriting control unit 20
Writes the annotated leader line data on the drawing data displayed on the display 3 and stored in the memory 19 (step S10), and proceeds to the next process.

Here, an example of a specific operation in this system will be described in detail. First, as shown in FIG.
In the menu on the editing screen of the AD system,
When "execute" (annotation means entry of an annotation other than drawing such as a dimension line and a leader line), a menu as shown in FIG. 4 is displayed. In this menu, "leader line"-"element" If you select (meaning that a leader line is used as an element), a menu as shown in FIG. 5 is further displayed. For example, "Please specify the type of leader line" is displayed at the bottom prompt line on the display 3 screen. Is displayed, the operator is required to specify the type of leader line to be drawn. The selection and change of these menus are performed by the operator operating the cursor movement key or the mouse of the input device 2 while moving the cursor on the menu while watching the editing screen of the display 3.

In the menu of FIG. 5, when the user selects “with annotation”-“execute” (meaning the execution of the annotation with leader) to enter the leader with annotation, the mode changes to the leader with annotation annotation creation mode. A menu such as 6 is displayed. In this menu, normally, "Recall"-"Execute" has already been preferentially selected at the time of display.

In this state, as shown in FIG. 6, a message "Please enter the text of the note" is displayed on the prompt line, thereby requesting the operator to input the text of the note of the leader line with the note. Is done. In this case, when a character string is normally input, the character string is input by operating the keyboard or the like of the input device 2 by an operator. When the input of the note text is completed, the state is as shown in FIG.

In the menu of FIG. 6, "Recall"-
When "execute" is selected, a character string which is input immediately before and held in the recall buffer is input. In the menu of FIG. 6, when the cursor is placed on a character string already existing on the drawing and "Text"-"Execute" is selected, the character string specified by the cursor is input. In the menu of FIG. 6, when "File"-"Execute" is selected and a file is selected, a character string stored as a file is input.

In the menu shown in FIG. 7, in a normal case, "automatic recognition"-"execute" is already preferentially selected at the time of display. In this state, as shown in FIG. 7, the display of "Please indicate the first point" is displayed on the prompt line, thereby requesting the operator to specify the start point of the leader line with annotation. When the start point is designated by operating the mouse or the like, as shown in FIG. 8, a prompt "Please designate a node" is displayed on the prompt line on the screen, so that the operator is notified of the node of the leader line with annotation. Is required.

The node specified in FIG. 8 is literally a bending point of the leader line in the case of a one-point broken leader line, but is the end point of the leader line in the case of a straight leader line. Therefore, in order to facilitate the pointing operation, the cursor in the case of the nodal point designation is an auxiliary line corresponding to the leader line and a (straight line leader line) between the starting point and the designated point of the node as shown in FIG. It is formed by a character frame indicating the position of the note character (if any).

When the position of the node is designated by operating the mouse or the like, as shown in FIG. 9, a message "Please indicate the drawing direction" is displayed on the prompt line on the screen, and the operator is prompted from the node. Is required to indicate the direction of the leader line. The leader direction indicated in FIG. 9 is the direction of the leader line in which the annotation character is arranged in the case of the one-point broken leader line. For example, it is designated by directly indicating the arrangement point of the annotation character after the leader is drawn. . Therefore, the cursor in the case of this direction designation is formed by an auxiliary line corresponding to the leader line from the node as shown in FIG. 9 and a character frame indicating the position of the note character, as shown in FIG. In the state of FIG. 9, it is also possible to stop the instruction of the pull-out direction by selecting “stop” on the menu without specifying the pull-out direction. Is stopped, the leader line is not a one-point broken leader line but a straight leader line.)

In FIG. 9, when the pull-out direction is designated, as shown in FIG. 10, it is bent from the start point designated in FIG. 7 to the node designated in FIG. 8, and moves in the direction designated in FIG. A one-point-break note-added leader line with a note character added to the extending leader line is written, and the menu returns to the same menu as in FIG. If the instruction of the drawing direction is stopped in the state of FIG. 9, as shown in FIG. 11, a note character is added to the leader line from the starting point specified in FIG. 7 to the node specified in FIG. 8. In addition, a leader line with a straight note is written, and the display returns to the same menu as in FIG.

In these cases, by returning to the menu similar to that shown in FIG. 6 instead of the menu similar to that shown in FIG. 5, it is possible to repeat the input of the note and the designation of the leader line. Can be entered continuously. Further, in order to easily and appropriately arrange the annotation character string, as shown in FIGS. 12 and 13, for example, as shown in FIGS. Is also on the right side (positive direction of angle), 90 ° <θ ≦ −9
In the range of 0 °, it is automatically arranged on the left side (the negative direction of the angle) of the leader line, and the leading direction of the straight leader line can be set in various directions as shown in FIG. The drawing direction after the node of the one-point breakout line is shown in FIG.
As shown in FIG. 3, only the horizontal and vertical directions may be set, and if an intermediate value is specified, it may be drawn in the closest direction.

Of course, the drawing direction of the annotation-provided leader line may be any direction in which the straight leader line is set in any direction, without setting the one-point broken leader line in the horizontal and vertical directions. The one-point breakout line may be in any direction, and these may be appropriately selected as desired. In this manner, the annotated leader line can be easily and appropriately written.

[0034]

As described above, according to the present invention, when a leader line with a note is drawn on drawing data, a note character is input, and the starting point of the leader line is designated on the drawing. To indicate the node of the leader line, to indicate on the drawing the direction in which the leader line is to be bent from the node, determine whether this direction instruction has been made or the direction instruction has been stopped, and stop the direction instruction. When the instruction is given, a leader line data with annotation is added to the leader line from the start point to the node, and when the direction is instructed, the leader line is bent at the node from the start point. Then, a leader line with the annotation is generated for the leader line in the bent leader direction, and the leader line data with the annotation is written on the displayed and stored drawing data. Easy as desired And appropriately can be created, it is possible to provide the annotated lead line operation NaruSo <br/> location that can realize a significant simplification of the operation.
