What is the CAD Preference Mixed Import Resolution used for?
The CAD Preference Mixed Import Resolution exists because the Ansys Workbench mesher can only accept Parts that contain "bodies" consisting of either "all solid" or "all surfaces".
Part1 contains multiple bodies with both solids and surfaces.
The Ansys Workbench CAD preference Mixed Import Resolution is a filter that says:
If a part containg multiple bodies consisting of different types is encountered, Which type shall be allowed to pass through?
In the example above:
Setting "Mixed Import Resolution" to "None" will not allow any bodies of Part1 to pass through.
Setting "Mixed Import Resolution" to "Solid" will allow only the solid bodies of Part1 to pass through.
Setting "Mixed Import Resolution" to "Surface" will allow only the surface bodies of Part1 to pass through.
The "Mixed Import Resolution" setting has no effect on Part2 or Part3, as these parts contain bodies consisting of a single type. Both Part2 or Part3 will be allowed to pass through.
- When you see the "no valid bodies found" message, then this often means that you may need to set a Geometry Import Option in Workbench to "filter" the import.
- A multi-body PART can consist of all solids bodies or all surfaces, but not a mix of both types.
Many ProE and SolidWorks parts seem to be made in this way.
- In 12.0, a combination of Line and Surface body type will be allowed as part of the "Mixed Import Resolution" filter selection.
