2. Description of the Related Art Some CAD systems have a function for writing a radius dimension, a diameter dimension, an arc length dimension, etc. of a circle or an arc in drawing data to be created.
In the writing function of the radius dimension, the diameter dimension, and the arc length dimension of the circle or arc in the conventional CAD system, the dimension between the circle or arc to be measured and the dimension corresponding thereto is measured at the time of dimension measurement or dimension at the time of writing. Although lines are related to each other when they are created, if the dimension lines are created and written as dimension data, the relationships are lost. That is, the radius dimension, the diameter dimension, and the arc length dimension of a circle or arc in the conventional CAD system are
Once written, the size data consisted of simple graphic and character data. Therefore, the radius dimension, diameter dimension, and arc length dimension of these circles or arcs are treated as simple graphic and character data even when the drawing data is edited.

Therefore, in the conventional CAD system, when the drawing is edited, if the circle or arc which is the target figure of the radius dimension, the diameter dimension, and the arc length dimension of these circles or arcs is changed or moved, the original Once you have deleted the radius, diameter, and arc length dimensions of the circle or arc, create the circle, arc radius, diameter, and arc length dimensions again for the changed or moved circle or arc. , Had to write. Therefore, for the operator, the radius dimension, diameter dimension,
Further, changing or moving the circle or the arc, which is the target figure of the arc length dimension, was very complicated work.

The present invention has been made in view of such circumstances, and when changing or moving a measured element which is a graphic element to be measured of dimension data, the dimension data is also changed or moved. It is an object of the present invention to provide a drawing editing method and device which are automatically changed in accordance with the above-mentioned conditions and have improved operability.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic structure of a CAD system incorporating a drawing editing apparatus according to an embodiment of the present invention. In the CAD system of this embodiment, when creating and writing size data such as radius size, diameter size, and arc length size of a circle or arc, the size data is stored in association with the measured element of the size data, and the size data of these size data is stored. When changing or moving the measured element, it is possible to re-measure the measured element that has been changed or moved to change the dimensional data and store it again.

The CAD system shown in FIG. 1 comprises a CAD processing section 1, an input device 2, a display 3, an output device 4 and a storage device 5. The CAD processing unit 1 is a CPU
A central processing unit (not shown) is included, and CAD processing including drawing editing processing having a dimension element holding function is executed. The input device 2 is an operation input device such as a keyboard,
A pointing device such as a mouse is used to input operation input information by an operator and other external information necessary for CAD processing to the CAD processing unit 1. Display 3
Displays necessary information such as processed image information by the CAD processing unit 1 and information related to input by the input device 2. The output device 4 includes a plotter, a printer, or the like, and a CAD
The image information processed by the processing unit 1 is output as a hard copy. The storage device 5 is composed of, for example, a disk device such as a hard disk device, operates in association with the CAD processing unit 1, and stores data such as image information before, after, and during processing as necessary. .

In this case, the CAD processing unit 1 uses the normal CA.
In addition to the configuration for executing the D process, the display control unit 11, the dimension data creating unit 12, the element change processing unit 13, for executing the drawing editing process having the dimension element holding function according to the embodiment of the present invention, Element movement processing unit 14, re-storing processing unit 1
5, a memory 16 and a writing / rewriting control unit 17 are included. The display control unit 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 dimension data creation unit 12 operates in response to an instruction input given by the operator via the input device 2 by an interactive operation with the screen of the display 3, for example, and a graphic such as a circle or arc already drawn. With the element as the element to be measured, processing is performed to create dimensional data such as the radius dimension, the diameter dimension, and the arc length dimension of a circle or arc.
Therefore, the dimension data creation unit 12 controls the display control unit 11 as necessary. The dimension data created by the dimension data creation unit 12 also includes information on the correspondence relationship with the measured element.

The element change processing unit 13 determines at least the circle or the arc which is the measured element of the dimensional data such as the radius dimension, the diameter dimension and the arc length dimension of the circle or the arc created by the dimension data creating unit 12. Performs processing to change graphic elements. The element change processing unit 13 also operates in response to an instruction input given by the operator via the input device 2 by an interactive operation with the screen of the display 3, for example. Therefore, the element change processing unit 13 also controls the display control unit 11 as necessary.

The element movement processing section 14 determines at least the circle or the arc which is the measured element of the dimension data such as the radius dimension, the diameter dimension and the arc length dimension of the circle or the arc created by the dimension data creating section 12. Performs processing to move graphic elements. The element movement processing unit 14 also operates in response to an instruction input given by the operator via the input device 2 by an interactive operation with the screen of the display 3, for example. Therefore, the element movement processing unit 14 also controls the display control unit 11 as necessary.

When the element change processing unit 13 or the element movement processing unit 14 changes or moves a graphic element such as a circle or an arc, which is the measured element of the dimension data, the re-storing processing unit 15 changes the shape of these graphic elements. The elements are restored according to the change or move operation, and when these graphic elements are the measured elements of the dimension data, the corresponding dimension data is also recalculated or moved and restored.

The memory 16 stores information including CAD drawing data to be displayed by the display control unit 11. The stored contents of the memory 16 are transferred to the storage device 5 as needed. The memory 16 may share the memory used in the normal CAD processing in the CAD processing unit 1. The writing / rewriting control unit 17 writes the dimension data associated with the measured element created by the dimension data creation unit 12 on the drawing data displayed on the display 3 and stored in the memory 16, and rewrites the data. According to the processing of the storage processing unit 15, the graphic data is changed or moved to be rewritten, and when the rewritten graphic element is the measured element of the dimension data, the corresponding dimension data is recalculated or moved to be rewritten.

Next, with reference to the flow chart shown in FIG. 2, a detailed description will be given of the operation particularly relating to dimension creation in the CAD system having such a configuration. The process shown in FIG. 2 is mainly a process related to the dimension data creation unit 12 of the CAD processing unit 1, and is assumed to be activated as an interrupt process by a command input during a normal drawing or editing operation in the CAD system.

First, when an operator selects and inputs a dimension creation command such as a radius dimension, a diameter dimension, and an arc length dimension of a circle or an arc through the input device 2 (step S1), the system applies the corresponding dimension. The creation mode is set (step S2). Once in dimensioning mode,
The operator gives instructions for the parameters (for example, the points on the circumference of the circle or arc, the center point, etc.) necessary for measuring the measured element such as the circle or arc to be measured on the drawing to be dimensioned. (Step S3). Such an instruction of the dimension creation target is performed by an operator's input request via the screen of the display 3 and the operator performing an instruction operation according to the input operation via the input device 2.

In this way, when the dimension creation target is designated in step S3, the dimension is measured based on it, and the dimension character and the dimension line corresponding to the measurement result are created together with the necessary auxiliary dimension line (step S4). ), And is stored in the memory 16 via the writing / rewriting control unit 17 in association with the corresponding measured element (step S5). In this way, when the dimension element is created and written on the drawing data displayed on the display 3 and stored in the memory 16, the system shifts to the next processing.

Next, the operation of the CAD system having such a structure, particularly regarding the change or movement of the graphic element, will be described in detail with reference to the flowchart shown in FIG.
It is assumed that the processing shown in FIG. 3 is started as an interrupt processing by a command input during a normal drawing or editing operation in the CAD system. First, when the operator selects and inputs a graphic element change or move command as an edit mode instruction via the input device 2 (step S11), it is determined whether the command is a graphic element change command or a graphic element move command. (Step S12).

When it is determined in step S12 that the command for changing the graphic element is given, the system enters the change mode, and the processing is mainly performed by the element change processing unit 13. First, the operator gives an instruction of the graphic element to be changed (step S13), and then the operator gives an instruction of the changed content such as the radius change for the instructed graphic (step S14).

When the change contents of the graphic element to be changed are instructed in step S13 and step S14, the element change processing unit 13 performs a specific change process of the graphic element (step S15), and the change of the graphic element is performed. According to the processing result, the re-storing processing unit 15 and the writing / rewriting processing unit 1
7 is displayed on the display 3 and the memory 16
The drawing data stored in is rewritten (step S16).

When the graphic element is changed / restored in step S16, the related dimension having this graphic element as the measured element is remeasured and changed (step S17), and according to the result of the change processing of the related dimension, The drawing data displayed on the display 3 and stored in the memory 16 is rewritten via the re-storing processor 15, the writing / rewriting processor 17, etc. (step S18). In this way, when the drawing data is rewritten and the graphic element and the dimension data are changed, the system shifts to the next processing.

If it is determined in step S12 that the command for moving the graphic element has been given, the system enters the moving mode, and the processing is mainly performed by the element moving processing unit 14. First, an operator gives an instruction of a graphic element to be moved (step S19), and then an operator gives an instruction of a moving condition such as a movement destination position for the instructed graphic (step S20).

When the moving conditions of the graphic element to be moved are instructed in steps S19 and S20, the element moving processing unit 14 performs a specific moving process of the graphic element (step S21), and the moving of the graphic element is performed. According to the processing result, the re-storing processing unit 15 and the writing / rewriting processing unit 1
7 is displayed on the display 3 and the memory 16
The drawing data stored in is rewritten (step S22).

When the graphic element is moved / restored in step S22, the related dimension having this graphic element as the measured element is moved in correspondence with the movement of the graphic element (step S2).
3) According to the result of the moving process of the related dimensions, the drawing data displayed on the display 3 and stored in the memory 16 via the re-storing processing unit 15, the writing / rewriting processing unit 17, etc. is rewritten (step S24). ). In this way, when the drawing data is rewritten and the graphic element and the dimension data are changed, the system shifts to the next processing.

Here, a specific example of the operation in this system will be described. First, there is a circular element having a radius of 15 mm as shown in FIG. 4 on the drawing data of the CAD system, and the dimension data creating unit 12 writes a radius dimension “R15” to the circular element as shown in the figure. Suppose This size data is stored in the memory 16 in association with the data of the circle that is the element to be measured.

Next, it is assumed that the element change processing unit 13 changes the radius of the circle as the measured element to 20 mm.
Then, the change result is displayed on the display 3 and written in the drawing data stored in the memory 16, and the radius dimension is recalculated and changed.
As shown in, the radius dimension “R20” is written.

Similarly in the case of the diameter dimension, as shown in FIG.
If the diameter of the circle is "φ20", the diameter dimension data also changes to "φ30" when the diameter of the circle of the measured element is changed, as shown in FIG. Furthermore, as shown in FIG.
If the diameter dimension of “0” is attached, as shown in FIG. 9, when the element movement processing unit 14 moves the circle of the element to be measured, the diameter dimension of “φ20” attached to this element to be measured. Also moves as the circle of the measured element moves.

As described above, the dimension data is stored in advance in association with the element to be measured, and when the element to be measured is changed or moved, the dimension data is changed or moved accordingly, so that the operator has good operability. Can significantly reduce the burden on

In addition to the above-described radius and diameter dimensions of the circle or arc, the arc length dimension and the like can be made to properly follow the dimension data when the element to be measured is changed or moved in the same manner as described above. Can be implemented. Further, the dimension data may be made to follow only one of the change and the movement of the measured element.

[0034]

As described above, according to the present invention, dimension data created by measuring a graphic element to be measured is stored in association with a measured element, and when the measured element is changed or moved, The measured element that has been changed or moved is re-measured so that the dimension data is changed and stored again, and the measured element that is a graphic element to be measured of the dimension data is changed or It is possible to provide a drawing editing method and apparatus with improved operability by automatically changing the dimension data when the element to be measured is changed or moved when the element is moved.
