Ansys Spaceclaim - cut/trim a .stl-part with a .step-part
I want to "cut/trim (schneiden)" two parts in Ansys Spaceclaim. One is a .stl-Part out of Ansys Mechanical which i got out of a topology optimization and the other is a .step-CAD-file (the start-file of the optimization).
I load the .stl-File in Ansys Spaceclaim and add the .step-file with the command/tool "assembly (Baugruppe)".
Then i want to "cut/trim (schneiden)" them to make sure no element of the smoothed .stl-part is outside of the geometrie of .step-Part. This looks like it works so far.
The problem is when i use the tool "facet check/test", i got 0 errors but the message "The net has more then one part. (Netz besteht aus mehreren Stücken)". And this looks like i causes problems to save the combined part as .step-file.
A solution is to use the command/tool "shrink wrapping (Schrumpfverpackung)" afterwards (1mm, 1°) but this changes my part-surface a bit. Is there any other solution to fix this problem? The problem is to combine the parts of the net without changing my part-surface.
Thanks a lot for your help.
