Problems solved by technology

[0004] At present, when processing CAD graphics, there are many objects, and it is very difficult to select some objects
[0005] In addition, since the user cannot predict the final processing effect of the control command on the pre-selected entity during the entity selection process, the user can only know whether the selected entity meets the needs after processing the selected entity through the control command.
If it is not satisfied, it proves that the selection is wrong, and the user has to execute the rollback command on the CAD to restore the entity to the state before the command processing and re-select, resulting in a lot of repeated selections, which invisibly causes a lot of unnecessary work , leading to a decrease in work efficiency

Embodiment Construction

[0033] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] see figure 1 and figure 2 , a method for frame-selecting entities using closed graphics, including the following steps:

[0035] S1. Select a closed polyline in the CAD drawing program; step 1 is specifically: when encountering a font, first process the font into a polyline, and process the font into a polyline through a line change command.

[0036] S2. Extracting objects whose contours are inside the polyline, the objects include text layers.

[0037] Specifically, the following steps are included in S2:

[0038] S21. In the CAD system, use the interface provided by the functional fu...

Abstract

The invention discloses a method for performing frame selection of an entity by using a closed graph. The method is characterized by comprising the following steps of S1, selecting a closed polyline in a CAD drawing program; S2, extracting an object with a contour in the polyline; and S3, moving the object to a new layer. According to the method, the problem of reduced working efficiency of object selection is solved, and the problems of time waste, high error rate and high missing rate due to manual selection by users are avoided, so that the effect of improving the working efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of graphics processing, in particular to a method for frame-selecting entities by using closed graphics. Background technique [0002] With the continuous development of information technology, CAD graphics system software has become an indispensable drawing tool for drafters or designers. Due to the improvement of technology level and the expansion of storage device capacity, designers often draw many entities in one CAD drawing. Such a large and dense collection of entities brings great difficulties to CAD system operators when selecting single or partial entities. The denseness of entities reduces the probability of users selecting the target entity. [0003] In general, the entities of the CAD graphics can be processed through the control commands in the CAD system, and the control commands can include commands such as trimming entities, offsetting entities, chamfering entities, mirroring entities, and...
