Hello

I have a geometry in pmdb format. The file is attached. Here is the geometry:

 

I want to save it in STEP or IGES format. I opened it with Design Modeler and it looked good and tried to save it in STEP (or IGES) format:

 

Then I tried to open the STEP geometry file that I had saved with ANSYS WORKBENCH and surprisingly this is what I see when I open it:

 

Which is almost nothing. The problem is that ANSYS can not open the STEP (or IGES) file that created itself. The geometry only appears good when imported as pmdb. I expect to get the same geometry after saving and opening it in STEP or IGES format. 

Does anybody know how I can  fix this issue? Thanks in advance.

I opened the pmdb file in SpaceClaim 2019 R2 and found a faceted Surface Body.

You can save this as a STL file if you want to access the facets outside of ANSYS.  I can read that STL file back into SpaceClaim and get the same object back. The Student license has no limitation on the number of facets on STL files and faceted surface bodies. There are 17,432 facets.

Your issue is you are trying to write a facet body to a STEP file. Don't do that. Convert the facet body to a solid body, then you can save the solid geometry into a STEP file, but only if you have an Academic (unlimited) license. You can't do this with the Student license because of the 300 face geometry limit.

If its not possoible in student version then what is the solution to save the created geometry in design modeler into .step or .iges format?
