Three-dimensional modeling system and method for prefabricated parts

Abstract

The invention provides a three-dimensional modeling system and method for prefabricated parts. The three-dimensional modeling system comprises a modeling rule maintenance module, a frame model base maintenance module, a whole machine parameterization modeling module and a three-dimensional model generation engine, wherein the whole machine parameterization modeling module is used for reading and analyzing to-be-built frame models of the prefabricated parts and modeling rules of the frame models in a frame model base, instantiating the frame models according to input part types, characteristic types and parameters, and building the parts and assembly models of the prefabricated parts; and the three-dimensional model generation engine is used for generating three-dimensional models of the prefabricated parts according to the built parts and assembly models of the prefabricated parts. According to the three-dimensional modeling system and method, the modeling rules and the frame models of the prefabricated parts are separated, the modeling rules of the prefabricated parts can be added and modified conveniently, and complete machine parameterization modeling meeting different design requirements as well as the three-dimensional models of the prefabricated parts can be generated rapidly through general and customizable part bases and the modeling rules.

Description

technical field [0001] The invention relates to the field of three-dimensional modeling, in particular to a three-dimensional modeling system and a three-dimensional modeling method of prefabricated components. Background technique [0002] With the development of CAD / CAM technology, parametric design has become one of the most popular application technologies in CAD, and it is playing an increasingly important role in the manufacturing industry. At present, engineering design has been transformed from traditional data resource-intensive to information-intensive and knowledge-intensive. In order to avoid a large number of repeated development work, improve the efficiency of prefabricated components, and save development costs in the process of prefabricated component design, appropriate parameters need to be adopted. The three-dimensional modeling of prefabricated components is carried out by using the modernized design method, so that the second design and subsequent design...
