The Study on Automatic Extraction and Conversion of Assembly Relation
Yan Xue Dong, Li Mei · Applied Mechanics and Materials · 2014
Aim at the assembly model of three-dimensional CAD focusing on determining the geometric location relationship of parts, the constraints define of assembly being inconsistent, this paper put forward the concept of assembly relationship to describe the geometry connecting relationship between the parts. The cooperation, insert and tangent constraints of inventor assembly are converted to pasting, centering and tangency of retrieval model, and marked with the attribute. This assembly model can support retrieving assembly, realize the effective management of the model.
