Abstract

The invention discloses an automatic graph cutting method and apparatus of a CAD vector graph. The method comprises: a target CAD vector graph is obtained; a graph cutting generation command inputted by a user is received and a plurality of preset graph cutting models for carrying out graph cutting on the target CAD vector graph are displayed based on the graph cutting generation command, so that the user can carry out selection; according to the graph cutting model selected by the user, a plurality of screenshot frames corresponding to the graph cutting model are generated at the target CAD vector graph, so that the target CAD vector graph can be segmented into a plurality of corresponding screenshot frame areas; and according to the graph cutting model and the obtained screenshot frames, cut vector graphs corresponding to the screenshot frames are generated. In addition, the invention also discloses an automatic graph cutting apparatus of a CAD vector graph. Therefore, automatic cutting of the CAD vector graph can be realized, so that the cutting efficiency of the CAD vector graph as well as the cutting quality of the CAD vector graph can be improved.

Description

technical field [0001] The invention relates to the technical field of vector graphics, in particular to a method and device for automatically cutting CAD vector graphics. Background technique [0002] The vector elements (such as lines or points, etc.) of CAD vector graphics are generally many and dense, so if the CAD vector graphics are reduced for printing, the printing will be blurred. The existing practice is to cut the CAD vector diagram into printable standard drawings (such as A4, A3 or A5 drawings) by business personnel through a series of repeated steps (frame selection, movement, frame setting, etc.), Then print them one by one. However, the efficiency of cutting and printing CAD vector graphics by manual cutting is relatively low, and it is easy to affect the quality of cutting pictures due to human misoperation, resulting in a decline in the quality of cutting pictures. Contents of the invention [0003] In view of the above problems, the object of the prese...
