Description

[Detailed Description of the Invention] [Outline] Regarding a CAD data dividing / editing method capable of generating a drawing intended by a designer and not inconsistent with CAD data, the designer can change the CAD data. The CAD-designed drawing data is designed to be divided into those that are impossible and those that are impossible, to ensure the logical consistency between CAD data and drawings, and to avoid re-operation even when CAD data is changed. Stored in CAD database,
When interfacing with a generic drawing editor, use CA
D The data is read from the database, and the figures that cannot be changed by the designer and the figures that can be changed are classified and stored in the drawing database. When editing with the general-purpose drawing edit editor, the figures that cannot be changed cannot be changed. ,
Other figures can be added / corrected as desired, the created drawings are stored again in the drawing database according to the classification, and when CAD data is changed, only the newly created figures are changed by the general-purpose drawing editor. To configure.

[Field of Industrial Application] The present invention uses CAD (Computer Aided Design) data as data that does not allow intervention such as addition or modification by a designer in a general-purpose drawing editing editor, and data that allows such addition or modification. The present invention relates to a CAD data dividing / editing method capable of dividing a drawing into a drawing intended by the designer and generating a drawing which is consistent with the CAD data.

[Prior Art] Basic parts of the output circuit diagram (see Fig. 5) and printed circuit board output mounting diagram (see Fig. 6) in CAD are saved in advance as CAD data. In some cases, the CAD output drawing may be added or modified to the drawing intended by the designer in the post-processing stage.

The conventional method is to use CA output on paper.
There are a method of adding or modifying by handwriting to the D output drawing, and a method of interfacing with a general-purpose drawing editing editor to edit with an image on the CRT screen as shown in FIG.

FIG. 8 is a diagram showing a conventional operation flow in the case of addition to a drawing or correction by a general-purpose drawing editing editor.
If you specify drawing output on the CAD design screen, the required drawing is called from the CAD database.

In the case of handwriting (manual) addition or correction, the drawing data is delivered to an output device, the drawing is output to a dedicated sheet, and the drawing is added or corrected by handwriting.

On the other hand, in the case of interfacing with a general-purpose drawing editing editor, the drawing output is temporarily stored in the drawing database, and the editor edits or corrects the drawing while referring to it, and saves it in the drawing database when the design is completed. The drawings of the drawing database can be output to an output device as needed.

[Problems to be Solved by the Invention] However, in the method of correcting by handwriting, since the CAD drawing output paper is electrostatic paper, it is difficult to add it and it is very difficult to erase it. In addition, when the data on the CAD side is changed, it is necessary to repeat the same correction operation on the paper, which results in a lot of man-hours and erroneous entry.

On the other hand, in the case of the method of handing over to the general-purpose drawing editing editor, once the CAD data is corrected, reprocessing due to changes in the data on the CAD side is necessary, and waste of man-hours and erroneous entry will not be handwritten. As tedious as it is. Furthermore,
In this method, there is a problem that the standard such as the standard shape of the circuit symbol that satisfies the requirements for CAD is arbitrarily changed by the designer's judgment and operation. Fig. 9
It is a figure which shows an example of the basic figure designed beforehand by CAD and provided to a user. FIG. 10 is a diagram showing an example of a drawing edited by a general-purpose drawing editing editor. In Figure 10, the part marked with a cross is the part where the correction was made, disconnection (deletion) and connection (addition)
Shows the case where is added. When corrected in this way, there was a problem that a logical inconsistency with the CAD design database (basic figure: FIG. 9) eventually occurred, and the meaning of the basic figure was lost.

The object of the present invention is to divide the CAD data into those that can be changed by the designer and those that cannot be changed, guarantee the logical consistency between the CAD data and the drawing, and avoid re-operation even when the CAD data is changed. It is to provide the CAD data division / editing method.

[Means for Solving the Problems] FIG. 1 is a principle flow of the CAD data dividing / editing method of the present invention.

When storing CAD-designed drawing data in a CAD database (step) and interfacing with a general-purpose drawing editor,
The data is read from the CAD database and the figures that cannot be changed by the designer and those that can be changed are assigned a specific code and classified into classes and stored in the drawing database (step), which cannot be changed when editing with the general-purpose drawing editor. It is not possible to change the figure, and it is possible to add or correct any other figure part (step), and the created drawing is stored again in the drawing database according to the classification (step), and the CAD data is changed. Occasionally, the figures other than the newly created figure are changed with a general-purpose drawing editor (step).

[Operation] When the drawings classified into classes according to the present invention are edited in a general-purpose drawing editing editor, the figures that cannot be changed cannot be changed, and other figures can be arbitrarily added / corrected. Guarantees a logical match with the CAD database.

The drawings created by the general-purpose drawing editor can be saved again in the drawing database according to the classification.

When the CAD data is changed, the figure part newly created by the general-purpose drawing editing editor is not changed, and only the other figure data is changed. As a result, there is almost no need to reprocess the newly created figure.

[Embodiment] FIG. 2 is a diagram showing an operation flow of the present invention, and FIG. 3 is a CAD.
It is a figure which shows an example of the classification in the case of dividing into the data which a designer can change and the data which cannot be changed.

The classification is as follows. Classes 1 to 100 (classification (a)) are given to the symbol position, shape, line connection, etc. in the circuit diagram and the part shape, position, etc. in the mounting diagram as those that cannot be changed by the designer.

Classes 101 to 150 (classification (b)) are given to the comments in the circuit diagram and the part symbols in the mounting diagram as those that are allowed to be changed by the designer.

Classes 151 to 255 (classification (c)) are given to the notes and the like in the circuit diagram and the instruction and the like in the mounting diagram so that the designer can appropriately add and correct them.

Such classification is done on the CAD design screen 1,
The classified data is stored in the CAD database 2. When interfacing to the general-purpose drawing editing editor 5, the interface 3 separates the data according to the classification by the interface program and stores it in the drawing database 4. The general-purpose drawing editing editor 5 outputs the data of the drawing database 4 as a drawing to the CRT screen, but the designer can add or correct only figures other than classes 1 to 100.

The corrected / corrected figure can be stored again in the drawing database 4 (in the figure, the drawing database is shown as being divided into two for convenience of description). FIG. 4 is a diagram showing an example in which the circuit diagram has been retouched. The broken line portion in the drawing is the retouched portion by the general-purpose drawing editing editor. The drawing data created in this way can be output to the output device as the drawing 6 as required.

When the CAD data (basic figure) of the CAD database 2 is changed, only the classification (a) and (b) parts are newly replaced,
The classification (c) part remains unchanged. Therefore, reprocessing is almost unnecessary depending on the degree of modification to the classification (b) part.

In addition, the class setting of CAD data can be changed appropriately, and it has the extensibility as a general-purpose drawing editing system.

[Effects of the Invention] As described above, according to the present invention, the CAD data is divided into those that can be changed by the designer and those that cannot be changed, and the logical consistency between the CAD data and the drawing is guaranteed. Moreover, it is possible to avoid re-operation even when changing CAD, and the following effects are obtained.

The logical consistency of the CAD database is guaranteed when designed in a generic drawing editor.

It is easy for the designer to add or modify.

Reprocessing is easy when changing CAD data.

It is possible to base drawings.
