Embodiment Construction

[0019] Take the simple analysis of the connection relationship of each graphic element in the CAD drawing as an example:

[0020] (1) Definition of primitives: Since a series of basic primitives are defined inside CAD, and the connection relationship between primitives is not accurately defined except for line primitives, it is necessary to define a unified way Connection judgment, the method is as follows:

[0021] A. Define the required primitives in the form of blocks.

[0022] B. Add unified special terminals on the block as the basis for judging the connection relationship. The definition of a special terminal is as follows: a block composed of a circle with a radius of r (r is small enough) and a point whose center position is P, so that the judgment between all primitives is based on the relative point P of each primitive ; while a circle with radius r is used as a prerequisite for identifying the P terminal and providing the CAD adsorption function.

[0023] C. Defi...

Abstract

The invention discloses a CAD (Computer-Aided Design) network topological graph analysis method based on a rapid group search technology. The CAD network topological graph analysis method is characterized by comprising the steps of: self-defining pixels, expanding attributes, making a network topological graph according to the defined pixels, and figuring out various linear connection relations by using an algorithm so as to calculate the topological relation among all the pixels. According to the invention, the problem of great manpower and financial resource waste generated because graphical analysis and treatment is performed by mostly developing a set of system singly and adopting a pixel self-definition manner in the prior art is solved. According to the CAD network topological graph analysis method based on the rapid group search technology, many graphical analysis systems can be developed by being established on the CAD so as to achieve the effect of getting twice the result with half the effort.

Description

technical field [0001] The invention relates to a method for analyzing network topological diagrams, in particular to a method for analyzing CAD network topological diagrams based on fast group search technology. Background technique [0002] As a computer-aided design software, CAD is constantly developing its concept and connotation. Its powerful functions of product and engineering design, drawing, and writing technical documents have been recognized by everyone. However, for image analysis software, most of them are solved by developing a separate system and customizing graphic elements, which is very cumbersome and troublesome. At the same time, it requires a lot of manpower and financial resources to develop the system separately, which increases the cost of the enterprise. If the topological analysis of graphic elements can be performed quickly on CAD, many graphic analysis systems can be developed on CAD, so as to achieve twice the result with half the effort. Cont...
