Embodiment Construction

[0048] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0049] figure 1 A flow chart showing a method for managing a CAD library according to an embodiment of the present invention includes the following steps:

[0050] Step S10, acquiring the graphic picked by the user;

[0051] Step S20, decomposing the graphics into basic primitives including straight lines, circles and or arcs;

[0052] Step S30, obtaining the dimension annotation of the basic primitive picked up by the user;

[0053] Step S40, acquiring the base point set by the user;

[0054] Step S50, obtaining the constants, variables and or formulas based on the base point of the basic primitives corresponding to the dimensions input by the user;

[0055] Step S60, constituting constants, variables and or formulas as constraints to obtain icons;

[0056] Step S70, add the icon into the gallery.

[0057] It can be seen that ...

Abstract

The invention provides a gallery management method for CAD, comprising the following icon defining steps: a figure collected by an user is obtained; the figure is decomposed to basic primitives comprising straight line, circle or circular arc; the size marking of basic primitive picked up by the user is obtained; a base point set up by the user is obtained; constant, variables and / or formula, based on the base point, of the basic primitive corresponding to the size marking input by the user are obtained; the constant, the variables and / or the formula form constraint so as to obtain icons; and the icons are added into the gallery. The invention can permit users to conveniently and quickly expand the gallery and draw common figures with a parameterized gallery, which dramatically improves drawing efficiency.

Description

technical field [0001] The present invention relates to the field of CAD (Computer Aided Design, computer-aided design), in particular to a library management method for CAD. Background technique [0002] In the CAD drawing process, it is often found that various symbols with the same structure (or similar) but different sizes (in many cases are standard parts, and there are also non-standard parts). If these graphics are manually drawn each time, it will undoubtedly take a lot of time. Therefore, some CAD software provides a library for managing commonly used graphics. In the process of drawing drawings, users only need to select the type or structure of the graphics to be drawn from the gallery, and determine the key dimensions of the selected graphics, and then they can quickly draw the desired graphics. [0003] In the process of implementing the present invention, the inventors found that the existing library cannot be defined by users as parametric icons, so it is in...
