| Abstract: | Aiming at the 3D spatial assembly sequence reasoning problem,a 3D-Geometry Constraints Analysis(GCA) method was proposed.Integrated with the Oriented Bounding Box(OBB) and Separation Axis Theory,the assembly GCA method was extended to be able to solve the 3D assembly problems.Accordingly,the corresponding computer-aided analysis system was developed and illustrated by a case study.The analysis results demonstrated that the 3D-GCA method was able to deduce the 3D Assembly Precedence Relations(APRs)and the ge... |
