Description
Technical Field
The invention belongs to the technical field of secondary development, and particularly relates to a self-adaptive instantiation method and a self-adaptive instantiation system.
Background
The three-dimensional modeling of parts is an important design link in the production and manufacturing of batch parts, and the traditional modeling mode mainly comprises the steps of firstly drawing sketches of two-dimensional planes by using computer aided design software (CATIA, SolidWorks, UG and the like), and then carrying out a series of characteristic transformation and Boolean operation on the sketches to further obtain the final three-dimensional effect. However, in the face of repetitive drawing with the same complicated structural form or a design scene with similar structural form but different size parameters, the modeling method is very redundant, consumes a lot of time and energy of designers, slows down the working efficiency, and is also prone to errors.
In the face of such a design scenario, many enterprises also adopt corresponding methods to avoid the problems of low repetitive drawing efficiency and high error rate. Because the three-dimensional model library built in the existing CAD software in the market is inconsistent with the self standard of each enterprise, and a user cannot modify and add a custom model, the built-in model library has great limitation and cannot meet different use requirements of each enterprise. Therefore, some enterprises begin to create own enterprise model libraries, which actually improve efficiency to a certain extent compared with the traditional modeling mode, but are still poor in idea. Because the designer needs to pass through a screening stage of a mass data model each time when calling a model, and also needs to manually import, identify and modify key parameters and remove useless parameters one by one, the automation degree is low, and the solution has low efficiency.
