Abstract

PURPOSE:To improve work efficiency by using one drawing and the others as the drawing for finish and drawings for daft respectively and setting designated luminance, color, and line type to only drawings for draft and generating contour elements of graphic elements selected from respective drawings on the drawing for finish. CONSTITUTION:A drawing 1b for draft and a drawing 1a for finish are displayed on a graphic display device 1 one over the other, and at this time, the luminance, the color, the line type, or the like is converted to display the drawing for draft. That is, a conversion processor 3 successively obtains coordinates of intersections of graphic elements selected from drawings 1a and 1b by the interactive operation. Respective graphic elements are generated on the drawing 1a for finish with data of only parts, where are surrounded with obtained intersection coordinates, as contour elements. Contour elements are generated in this manner to complete the drawing 1a for finish. Thus, drawing is efficiently performed in a band-writing manner.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention is applicable to CAD (Computer Aide).
This invention relates to a drawing method in which a plurality of drawings are simultaneously displayed on a graphic display and the drawings are completed using the graphical elements of each drawing in the D.D.Design system.

[Prior Art] In current CAD systems, a drawing structure that incorporates the concept of layers is generally used as a method for simultaneously displaying a plurality of drawings on a graphic display. One way to distinguish between multiple layers displayed on a graphic display is to display each layer in color, but the colors that can actually be used depend on the hardware,
Often limited by software performance.

Further, in order to complete a drawing using graphic elements on multiple layers, the following nine operations are usually performed. First, if it is necessary to distinguish between each layer screen that is displayed superimposed on the drawing for completion, display the layers in color, copy or project the graphical elements on the layer onto the drawing for completion, and then Create drawings through interactive operations.

[Problems to be Solved by the Invention] By the way, when a design worker creates a drawing by hand, he or she usually makes a draft and completes the drawing based on this.

On the other hand, when drawing using CAD, there is no concept of this "draft." For example, even if the original drawing (draft) is displayed on a graphic display and the completed drawing is drawn on top of it, conventional color display does not allow for both. This was insufficient for distinguishing between screens. In addition, when drawing the outline of vague geometric elements based on them, conventionally it is necessary to create several similar graphic elements until an appropriate graphic element is determined, and then delete unnecessary ones. The efficiency was poor.

This invention was made to solve the above-mentioned problems, and it is an object of the present invention to provide a drawing method that allows efficient drawing with the feeling of handwriting.

[Means for Solving the Problems] The drawing method according to the present invention sets one of a plurality of drawings superimposed on a graphic display as a completion drawing and the others as a draft drawing, and only the draft drawing is given a specified brightness. , color, and line type, and outline elements of the graphic elements selected from each of the above drawings are created in the final drawing.

[Operation] In this invention, the distinction between a completed drawing and a plurality of draft drawings is recognized based on an interactive operation, and only the graphical elements displayed on the graphic display that are designated as draft drawings are designated. Converts and displays data with conditions such as brightness, color, line type, etc. Then, using each of the above-mentioned drawings, outline elements of arbitrary graphical elements selected through interactive operations are created in a completion drawing.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a main part configuration diagram showing a drawing method according to an embodiment. In the figure, 1 is a graphic display, 2a,
2b is a drawing data file in which existing drawings and completed drawings are stored; here, drawing data file 2
The existing drawing 1a read from the drawing data file 2b and the plurality of existing drawings 1b read from the drawing data file 2b are respectively displayed as layered drawings on the graphic display 1. 3 is a conversion processor for realizing the drawing method of the present application, which recognizes the drawing 1a marked with - as a completion drawing and the other drawings 1b as draft drawings based on input from a design worker through interactive operations. Converts only the draft drawing 1b to data with specified brightness, color, line type, etc. and displays it.
It has a function of creating a contour element of an arbitrary graphic element selected by an interactive operation in the completion drawing 1a using a and lb.

Next, the operation will be explained. FIGS. 2(9) to (di) are explanatory diagrams showing the operation of the conversion processor 3 which creates outline elements based on a plurality of graphic elements in each drawing.

Figure 2 (a) and (bl are layer drawings, respectively. Here, the drawing of Figure 2 (b) is used to complete the drawing of Figure 2 (al), and the drawing of Figure 2 (al) is completed. Drawing 1a.

It is assumed that the drawing in FIG. 2 (bl) is recognized by the conversion processor 3 as the draft drawing 1b.
The draft drawing 1b (Fig. This is done by converting the line type, etc., but here it is represented by a dotted line.

The conversion processor 3 first converts each drawing 1a through an interactive operation.
, lb, the intersection position coordinates of the graphic elements selected from lb are sequentially determined. Next, for each graphical element, data of only the portion surrounded by the obtained intersection position coordinates is created as a contour element on the completion drawing 1a. FIG. 2 fdl shows a completed drawing 1a in which contour elements are created in this manner.

[Effects of the Invention] As described above, according to the present invention, one of the plurality of drawings displayed overlappingly on a graphic display is set as a completion drawing and the others are set as draft drawings, and only the draft drawing is given a specified brightness. In addition to the color and line type, the contour elements of the graphical elements selected from each of the above drawings are created in the final drawing, which brings a traditional hand-drawing feel to CAD drawings and makes the operation more familiar. Furthermore, since these outline elements are created from existing graphical elements, work efficiency is improved.
