気づき支援CADシステムにおける3D Annotated Model活用技術の開発

抄録

We developed an “ Insight CAD system” as one of the design support technologies. The purpose of the Insight CAD system development is to check design rules automatically on 3DCAD, and to provide information about the violation parts or the violation list for designers. In this paper, we developed 3DA model utilization function that obtains the type and size of parts from attribute information and uses them for assembly rule checking. By checking the rules using the 3DA utilization function, the following conclusions were obtained. 1) Compared to the conventional similar shape recognition function, there is no misdetection of material species. 2) Regarding screw fastening, it was confirmed that the check of the diameter and length of the screw hole can be correctly evaluated. 3) Compared to the conventional similar shape recognition function, it was confirmed that the check time was reduced by 75% by applying the 3DA model utilization function.
