Abstract

PURPOSE:To visually easily discriminate whether a graphic line element displayed on a drawing is the shape of reference parts or the shape of variation parts by its color and to quantitatively check also the adoption ratio of the reference parts by displaying it as numerical data. CONSTITUTION:A design work control part 31 controls a design work defining part 32 based upon information inputted by a data input part 1 and design work result information 5. Various information generated as the execution result of the defining part 32 is stored in the information 5 and its data are succeeded to a drawing preparing part 4. The preparing part 4 retrieves or generates a parts shape based upon the information 5 and displays the parts shape on a display device 2 by changing its color in accordance with reference parts or variation parts. The rate of the reference parts line element to the whole line elements on the drawing is displayed by numerical data.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for displaying a shape of a part by a computer, and more particularly to a generated CAD.
The present invention relates to a drawing display method, and more particularly to a discrimination display method and an apparatus thereof suitable for easily determining whether a standard part shape or a variable part shape is displayed based on the displayed drawing information to improve the efficiency of design work.

[0002]

2. Description of the Related Art For example, when designing devices such as electric motors based on computer assistance, conventionally, based on the shape specifications of the devices obtained from the design work, among the parts shapes standardized in advance. Moreover, the appropriate parts were manually selected. For this reason, the process before drawing creation and the process of drawing creation were separated with the aid of computer. Further, in order to recognize the characteristics of the part shape from the drawing, the character information is read. Specifically, based on the product shape specifications obtained in the design work, it is decided whether to search and place the standard part shape or to draw the variable part shape, and to approve whether the drawing result is valid or not. It is done in the process.

[0003]

The above-mentioned conventional technique is
Human work is required to adapt the standard part shape in drawing creation, and whether the part shape developed in the drawing faithfully reflects the product's shape specifications obtained in the design work. It is necessary to judge from the dimensional value and the annotation, and it is difficult to immediately recognize whether the shape is the standard part shape or the variable part shape because of the graphic lines of the same color.

For this reason, in the design work of devices such as electric motors, which has a short design time, human work is required to extend the work time and to have a drawing recognition ability for standardized devices. There is also the problem that design errors are easy to make in terms of optimal design and product reliability is poor as well as work efficiency.

An object of the present invention is to support an efficient drawing creation work by combining a design support program for determining product specifications and a drawing creation support program for determining a shape based on the design support program.

[0006]

The above object is achieved by organically combining a program for supporting the design of devices and a program for supporting the drawing creation.

The above object can also be achieved by providing a standard part shape in advance in a program for supporting drawing creation and providing attribute information for associating the registered standard part shape data with design result information.

The above object can also be achieved by automatically generating, manually inputting, and retrieving part shape data in a program that supports drawing creation.

The above object is also achieved by determining the graphic line color according to the processing type and displaying the graphic line differently.

Further, the above object is to obtain the graphic line of the part shape which is discriminated or generated according to the processing type or the geometrical information of the element, the ratio of the standard part data and the variable part data, and display the numerical value of the ratio on the screen. Achieved by

[0011]

[Function] Since the program for supporting the design of the devices and the program for supporting the drawing are organically combined, the figure line color is displayed differently between the standard part shape and the variable part shape,
It becomes possible to display numerical data of ratios, and it is possible to easily check drawing information such as the adoption status of standard parts, so that efficient drawing creation work can be performed.

FIG. 2 is a flow chart showing the operating procedure of the present system device. On the screen of the display device 21, an input setting screen composed of graphics and text data is displayed (not shown). First, in step 101, the designer inputs the design work on the input setting screen. In the next step 102, the input design work is "new design".
Or, it is determined whether or not it is a “design change” that can be made by modifying the existing design, and if it is an existing “design change”, the process proceeds to step 103 to search for the data that can be used before. .

In step 104, a tree structure diagram of each design work process divided into modules is displayed on the screen of the display device 21 (not shown).

In the case of "new design", first in step 203, a drawing only with a drawing frame without graphic lines is displayed, and in step 204, based on the design result information obtained in step 108, whether relevant part information already exists. Please search. In step 205, it is determined whether or not the corresponding component exists, and if it exists, step 207
Then, the retrieved part shape data is displayed on the screen of the display device 21. If it does not exist, step 206 generates part shape data based on the design result information. Step two
At 08, it is determined whether or not the part shape data is to be registered as the standard part shape data.
At 09, it is registered as standard part shape data, and step 21
Set the standard part color with 1. If not registered as standard part shape data, an automatically generated part color is set in step 210. In step 212, the standardization rate of the part shape displayed in the drawing is calculated from the geometric information amount.
