Embodiment Construction

[0035] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0036] Figure 2A is a structural diagram of a modeling device according to an embodiment of the present invention, such as Figure 2A As shown, the modeling device of this embodiment includes:

[0037] The first obtaining module 101 is configured to obtain a clipping target model.

[0038] The clipping target model is the object that the user wants to clip, for example, the clipping target model can be a solid or a surface body.

[0039] The second acquiring module 102 is configured to acquire a cropping tool model and a relative positional relationship between the cropping tool model and the cropping target model.

[0040] The relative positional relationship between the clipping tool mod...

Abstract

The invention discloses a modeling method and a modeling device. The modeling method includes: acquiring a cutting target model; acquiring a cutting tool model and the relative positional relation between the cutting tool model and the cutting target model; obtaining a cutting tool body according to the relative positional relation between the cutting tool model and the cutting target model; subjecting the cutting tool body and the cutting target model to the Boolean operation for cutting the cutting target model to obtain cut sheets of the cutting target model; determining a first sheet which is a sheet, needed to be reserved, in the cut sheets; and taking the first sheet as a modeling result. Using the modeling method and the modeling device can solve the problem of low design intent expression accuracy of modeling results in the prior art.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a modeling method and device. Background technique [0002] With the wide application of 3D CAD software in the manufacturing industry, the complexity of the models processed by the software is also increasing. The original CAD system tightly supported the intersection and merge operations between models, and the models involved in the operation were limited to cubes and cylinders; now the most advanced CAD systems have supported various types of surfaces including parametric spline curves and surfaces, B-spline surfaces, etc. Complex geometry representation method, and rich solid and surface modeling functions, but with the increase of CAD system functions, higher requirements are placed on the professional skills of engineers. [0003] Most of the existing technologies adopt the modeling method of first creating the tool body and then performing Boolean operations. Since such ...
