Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reference drawing output scale switching method for changing the scale of a reference drawing assigned to a drawing in a CAD system or the like.

[0002]

2. Description of the Related Art In a CAD system, reference drawings are sometimes used in order to reduce the size of drawing files and to facilitate uniform modification of specific portions of drawings. When allocating a reference drawing to a certain drawing, only information for identifying the reference drawing and allocation position information are stored in the drawing file. Then, the actual drawing data of the reference drawing is stored in another file called a reference drawing file. Therefore, for example, as shown in FIG.
In the case where a plurality of screws 22a, 22b, 22c having the same shape are described in FIG. 1, the basic shape of the screw 23 is registered as a reference drawing (reference drawing: RD) 24, and FIG. As shown in FIG. 18, only information for identifying the reference drawing 24 and arrangement positions 26a, 26b, 26c of the reference point 25 on the drawing 21 are stored. As a result, the amount of data in the drawing 21 can be reduced, and the screw 22 on the drawing 21 can be changed according to the specification change of the screw 23.
The shapes of a to 22c can be uniformly changed.

By the way, in general, CA
The drawing data handled in D is represented by an absolute value that does not depend on the display and output scale. Therefore, when outputting to a CRT display device or plotter, the output control unit is provided with the output scale of each drawing as a variable, and the drawing data read from the drawing file or the reference drawing file is based on the variable. The coordinates are converted and output. Therefore, when changing the scale of a drawing file, it is necessary to change the reference scale referred to in the drawing file to the same scale. There was a problem that the change operation was troublesome.

The present invention has been made in view of the above problems, and when changing the scale of a drawing, there is provided a method of switching the output scale of the reference drawing, which makes it easy to change the scale of the reference drawing assigned to the drawing. The purpose is to provide.

[0005]

A reference drawing output scale switching method according to the present invention allocates the reference drawing in the drawing according to information for specifying the reference drawing to be allocated and the allocation position, and outputs the drawing. The scale and the output scale of the reference diagram are provided as variables, respectively, the drawing and the reference diagram are output in a size based on the variable, and when switching the output scale of the reference diagram allocated in the drawing, the designated information is specified. Based on the specified scale of the variable indicating the scale of the specified reference map, the step of specifying the reference map to be scaled switching based on the specified scale, the step of displaying the current scale of the specified reference map, And a step of changing.

[0006]

According to the present invention, when the reference diagram to be scale-switched is specified based on the designation information, the current scale of the reference diagram is displayed. Therefore, a new scale can be determined based on this scale display. It is possible to easily decide whether to use the value. Therefore, the scale switching operation of the reference diagram can be extremely facilitated.

[0007]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a functional block diagram of a CAD system for implementing a reference diagram output scale switching method according to an embodiment of the present invention.

This system comprises an input means 1, a drawing / editing control means 2, an output control means 3, a drawing database 4, a reference drawing (RD) database 5, a display means 6 and a drawing means 7. The input unit 1 is composed of a pointing device such as a mouse, a keyboard, and the like, and is used for specifying line elements and coordinates to be created and modified, and for inputting various commands. Drawing / editing control means 2
Creates or modifies the contents of the drawing database 4 and the reference drawing database 5 according to the input information from the input means 1 or allocates the contents of the reference drawing database 5 to a predetermined file of the drawing database 4.

The drawing database 4 and the reference drawing database 5 have the contents shown in FIG. Each of the drawing files F1, ..., Fi, ... Of the drawing database 4 is composed of a set of element data, but for the portion to which the reference drawing RD is allocated, information (RDk) for specifying the reference drawing as element data. And its placement position (xj, y
j) and are stored. The substantive data of the reference diagram RD is stored in the reference diagram database 5.

The output control means 3 outputs the drawing data stored in the drawing database 4 and the reference drawing database 5 to the display means 6 and the drawing means 7 on a predetermined scale. The output scale of each drawing file and each reference drawing is stored in a variable called a plot scale 8. As shown in FIG. 3, the output scales stored in the plot scale 8 are independent values for each of the referenced drawing files (F1, F3) even if they are the same reference drawing (RDk). There is.

Next, the operation of the present system thus constructed will be described. Now, for example, when allocating a reference drawing to the drawing data 11 as shown in FIG. 4, the operation of the input means 1 selects and executes "graphic allocation" from the menu area 12 of the display means 6. At this time, the prompt line 13
The current display scale (1/1) of the drawing data 11 is displayed. When you execute "Figure allocation", as shown in Fig.5, the message "Please specify the type of drawing to be allocated" is displayed on the prompt line 13, so refer to the drawing to be allocated from the menu area 12. Specifies that it is (reference drawing). When "Reference drawing" is specified, the file name registered as the reference drawing is displayed in the menu area 12 as shown in Fig. 6, and the message "Please select the reference drawing to be assigned." Is displayed on the prompt line 13. Is displayed, the file name (for example, RD3) of the desired reference diagram is designated.

When the file name of the reference drawing is specified, the reference drawing 14 is displayed in a window format in a part of the drawing display area 10 as shown in FIG. 7, and the prompt line 13 is displayed.
A message "Please specify the allocation position." Is displayed, and the input means 1 is operated to move the cursor 15 to the allocation position in the reference drawing. This allows
As shown in FIG. 7, the reference diagram 14 is assigned on the drawing 11. On the drawing 11, a mark 17 indicating the arrangement position of the reference point 16 of the reference drawing 14 in the drawing 11 is displayed.

Next, the drawing 11 to which the reference drawing 14 is assigned
To change the display scale of, select "Change" from the menu area 12 in the edit mode as shown in FIG. When "Change" is selected, as shown in Fig. 9, the prompt line 13 "Please specify the item to be changed."
Is displayed, the “scale” is designated from the menu area 12. When "scale" is designated, as shown in FIG. 10, each scale value is displayed in the menu area 12, and "Prompt scale" is displayed on the prompt line 13. Therefore, for example, when "1/2" is selected, the drawing 11 is displayed with a reduced scale of 1/2 as shown in FIG. However, at this point, only the variables of the drawing file (for example, F1) of the plot scale 8 shown in FIG.
As shown in FIG. 1, the scale of the reference diagram is still 1/1.

Then, when "change" is selected again from the menu area 12 and the desired reference diagram is designated by the cursor 15 in the single mode (single designation) or the multi mode (plural designation) as shown in FIG. As shown in FIG. 13, a message “Please specify the item to be changed” is displayed on the prompt line 13. In response to this, when "scale" is selected again, as shown in Fig. 14, a message "Please specify the scale" is displayed on the prompt line 12 and each scale value is displayed in the menu area 12. Is displayed. Also, at this time,
The output control means 3 outputs the value of the plot scale 8 to the display means 6 under the control of the drawing / editing control means 2. As a result, as shown in FIG. 14, the prompt line 13 displays that the current scale of the reference drawing is 1/1. Therefore, the operator can easily specify the scale of the reference drawing as "1/2" based on the current scale display. Through the above procedure, as shown in FIG. 15, the scale change of the drawing data including the reference drawing is completed.

As described above, according to the output scale switching method of the reference diagram of the present embodiment, since the current scale of the reference diagram is displayed on the prompt line 13, the scale changing operation of the reference diagram is facilitated. Further, according to this embodiment, the scale can be changed by designating the reference diagram to be scaled, so that there is an advantage that the output scale can be applied as it is to the portion which is not desired to be scaled. is there.

If the scale of the reference drawing referred to in the drawing is necessarily changed due to the scale change of the drawing, in order to improve the operability, the scale of the drawing is changed when the scale of the drawing is changed. You may make it change the scale of the reference drawing referred to by unconditionally. In this case, for example, as shown in FIG. 16A, the plot scale 8 of the drawing file F1 and the plot scale 8 of the reference diagram RDk referred to in the file F1 are linked and changed, or Alternatively, the plot scale 8 of the drawing file F1 and the plot scale 8 of the reference diagram RDk may be the same variable.

[0017]

As described above, according to the present invention, when the output scale of the reference drawing is changed, the current scale of the reference drawing is displayed. Therefore, the scale of the reference drawing is changed according to the scale change of the drawing. This makes it easier to operate and the operation is easier.
