Creating sheet bodies from polygon faces

Use the InsertModel PreparationSurfaceFrom Polygon Face command to create a trimmed N-sided surface or bounded plane from polygon faces from the FEM.

This command is only available when the FEM is the displayed part and the CAD model is the work part:

  • If the FEM is associated with both an idealized part and a master part, you can create surfaces only in the idealized part.

  • If the FEM is associated directly to the master part (there is no idealized part), you can create surfaces in the master part.

For more information about setting the work and displayed part in Pre/Post, see FE model in context.

You can use this command, for example, to create CAD geometry from polygon faces extracted from mesh data using the Face from Mesh command.

The From Polygon Face command extracts edge information from the polygon face and uses that to create a sheet body as a trimmed N-sided surface. When creating a surface from a polygon face, the same limitations apply as when creating an N-sided surface. From Polygon Face does not consider interior points, and you cannot create a surface from a polygon face that contains holes or interior loops. For more information about N-sided surfaces in Modeling, see N-Sided Surface overview.
