I am N.J. I am trying to run a SW Plastics analysis on Polycarbonate Part that has to be over molded with a TPE. Both of them has complex geometries, I have tried importing both the files into a single part file but am unable to Mesh as the error shows " Should be one CAD Body". Next I imported the PC part and modelled the TFE part around it. This time when I mesh SW recognizes the entire body as a single part or cavity. Is there a way I can assign the PC part as an insert and the TFE part as a cavity and run the analysis. Also I should be able to assign different materials to those parts.
