Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a part drawing information change registration method for making a change to a set of graphic elements registered as part drawing information in a CAD system or the like.

[0002]

2. Description of the Related Art In a CAD system, a set of frequently used groups of graphic elements is registered as part drawing information, and part drawing information consisting of a plurality of registered graphic elements is handled as one set. The efficiency of drawing work is improved. Conventionally, when a corner R is added to a set of graphic elements that form part drawing information that has been registered once, or a change such as addition or deletion of graphic elements is performed by chamfering, After such a change operation, it is necessary to set the part drawing information registration mode again and register the part drawing information again.

[0003]

In the above-mentioned conventional system, when a graphic element is added or deleted to change the set of graphic elements registered as part drawing information, the part drawing information is re-established. Since it is necessary to perform the operation of re-registering the part drawing information in the registration mode of 1), there is a problem that the operation is complicated and the work efficiency is low.

The present invention has been made to solve such a problem, and even if a graphic element is added or deleted so as to change the set of graphic elements registered as part drawing information, An object of the present invention is to provide a part drawing information change registration method capable of continuing graphic editing processing without requiring mode change.

[0005]

A part registration information change registration method according to the present invention is a part registration information change registration when a change is made to a set of graphic elements registered as part drawing information. In the method, an edit step of changing, adding or deleting an arbitrary graphic element according to an operator's operation, and determining whether the edit target in this step includes a graphic element already registered as the part drawing information When it is determined that the step and the graphic element already registered as the part drawing information in this step are included, when the graphic element to be added or deleted to the edit target is included, A component drawing information changing step of adding or deleting a graphic element to be added or deleted from the component drawing information.

[0006]

According to the present invention, it is determined whether or not a graphic element already registered as part drawing information is included in the graphic elements included in the editing target, and if it is registered as part drawing information. If the included graphic element is included, the graphic element to be added or deleted included in the edit target is added to or deleted from the part drawing information to change the part drawing information. Therefore, the graphic editing operation can be continued without re-registering in the part drawing information registration mode. Therefore, working efficiency can be improved.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a schematic functional block diagram of a CAD system to which a part drawing information change registration method according to an embodiment of the present invention is applied. This system includes an input unit 1 such as a mouse and a keyboard, and a graphic edit processing unit 2 for adding edit operations such as changing, adding and deleting graphic elements to the created graphic data by operating the input unit 1.
In order to display the component drawing registration unit 3 for registering a set of graphic elements as component drawing information in the component drawing registration mode, the created and edited graphics and the cursor operated by the input unit 1 Display unit 4 such as a CRT display or liquid crystal display, and a CAD data storage unit 5 for storing the created and edited graphic elements as graphic data and for storing the part drawing information registered by the part drawing registration unit 3.
And is configured.

Next, the operation of the system thus configured will be described. FIG. 2 is a flowchart showing the operation when the parts drawing registration mode is designated. When the parts drawing registration is designated, a message prompting the designation of a group of graphic elements to be registered as the parts drawing information is displayed on the display unit 4. Therefore, in accordance with this message, the target graphic elements are input unit 1
Is designated by the operation of (S1). For example, in order to register a rectangular target figure 10 composed of linear elements S1, S2, S3, S4 as shown in FIG.
Either the linear elements S1 to S4 are designated by the cursor 11 one by one, or the target graphic 10 is moved to the cursor 1 as shown in the drawing.
The figure to be registered is specified by enclosing it with the rectangular area 12 set by the operation 1. When the designation is completed (S2), the creation of parts diagram information described later is started (S3). Next, the operator is prompted to input the accessory information to be added to the component drawing information, and an interactive operation is performed to input the accessory information such as the name of the component drawing information and the component code (S4). When the attached information is entered, the part drawing information is CA
The data is registered in the D data storage unit 5 (S5).

FIG. 4 is a diagram showing an example of graphic data, part drawing information, and auxiliary information constituting CAD data. The component drawing information is the element number and the index IDX to the next element.
Composed of and. The element number is information specifying the element number in the graphic data. Detailed data of each graphic element is described in the graphic data, and the element number serves as an index to the graphic data. In the graphic data, the part drawing index is described in association with each graphic element, and it is possible to access the corresponding part drawing information from any graphic element that constitutes the part drawing information of the graphic data. There is. The parts drawing information has a chain structure. In the illustrated example, the parts data IDX is converted from the graphic data.
When the address A1 is extracted by referring to
→ A2 → A3 → A4 → A50 A series of graphic elements and ancillary information that compose one part drawing are extracted in this order.

Next, an example in which the figure registered as the part drawing information is changed by using the figure edit processing section 2 will be described. That is, now, the graphic element S1 as shown in FIG.
, S2, S3, S4 rectangular target figure 1
0 at four corners, for example, a corner R as shown in FIG.
A case will be described where an edit operation for adding is performed. When the corner R process is performed on the upper right corner of the target graphic 10, the process shown in FIG. 6 is started. That is, first, it is checked whether the editing target is a graphic element registered as part drawing information (S11). If the edit target is not a graphic element registered as part drawing information, the process ends.

In the case of this example, by the corner R processing, a circular arc element S5 is newly added, and a linear element S1,
Since each end point b of S2 is changed to b'and b "so as to be connected to both ends of the circular arc element S5, the editing objects are the graphic elements S1, S2, S5.
Since 2 is a graphic element registered in the part drawing information, it is next checked whether or not there is a graphic element to be added / deleted as an edit target (S12). In this example, the graphic element S5
Is an additional element, this additional element is added to the part drawing information. As an additional procedure, the index of the part drawing is written in the part drawing index of the graphic data of the additional element, and the number of the additional element is added to the part drawing information. And
The index of the element having the index to the auxiliary information is changed to the index (address) to the additional element in the series of graphic elements constituting the part drawing information, and the index to the additional information is written as the index of the additional element.

By the above operation, the chain structure is changed. FIG. 7 is a diagram showing the contents of graphic data, part drawing information, and attached information at the time when the corners R are added to the four corners as shown in FIG. 5B. With such a data structure, the addition and deletion of the graphic element can be performed only by rewriting the index, so that the processing becomes extremely simple. In the above embodiment, the case where the graphic element is added has been described. However, even when the graphic element is deleted, the component drawing information is appropriately re-registered at the time of the graphic editing operation by performing the same process. .

[0013]

As described above, according to the present invention, it is determined whether or not the graphic element included in the object to be edited includes the graphic element already registered as the component drawing information. When the graphic element registered as the component drawing information is included, the added or deleted graphic element included in the editing target is added to the component drawing information or deleted from the component information, Since the parts drawing information is changed, the graphic editing operation can be continued without re-registering in the registration mode of the parts drawing information, and the working efficiency can be greatly improved. .
