A Proposal of the Topology CAD and CAE Integrated System for the Next Generation

3D-CAD system is needed for the Designing of plastic processing products that are required art-design. But the current use Boolean 3D-CAD system takes too match man-power of the operation, and design engineers can not use it directly. And this situation have made the degeneration of the design technology. We have developed the new topology-CAD system as next generation-CAD. Also the current CAE system has the same problems as CAD. And so, the design engineers depend on the out-source-technology. We have also developed the new genera- use-CAE system integrated in the Topology-CAD using particle analysis.
