problems about GDO
 
I am doing a optimization work about extrusion die. But I have a quetion now. I finished the design of experiments, but some design points failed to generate the geometry, so i want to delete these design pionts. So I change the Design of experiments type from central composite design to custom and delete the design points. It works and can update. But when I try to update the response surface, it comes error, the component response surface can not be updated. So what should I do?

The failed design points (DP's) are automatically inserted back into Parameter Set window.There will a current DP and the failed ones as a number DPxx. Just select them and right click Update selected design points.After it finishes, just go to Design of Experiments tab from Response Surface system and click update all, this should read in the failed DP's and you can generaate your response surface.Happens to me all the time using CADNexus reader for Catia.

Thanks. I think it does not work. These design points failed because they can not generate the geometry, it is the structure problem. When I selected the Dp and update selected design points, it also failed. So I need to delete them, and I have found the problem. When can change the respons surface type, it works. But i don't whether it is right to do it like this way.
