Import geometry from Spaceclaim - Named Selections

[balintkissecon]

Hi Everyone,

I want to simply import a Spaceclaim geometry into pymechanical. The geometry is imported but the defined named selections (groups) are not transferred. I followed the steps of the example tasks in the documentation, but it does not work:

geometry_path = "DD_surfaces.scdocx"
geometry_import_group = Model.GeometryImportGroup
geometry_import = geometry_import_group.AddGeometryImport()
geometry_import_format = (
Ansys.Mechanical.DataModel.Enums.GeometryImportPreference.Format.Automatic
)
geometry_import_preferences = Ansys.ACT.Mechanical.Utilities.GeometryImportPreferences()
geometry_import_preferences.ProcessNamedSelections = True
geometry_import.Import(
geometry_path, geometry_import_format, geometry_import_preferences
)
app.print_tree()

Anyone faced the same issue? Any ideas would be much appreciated!

Hi @balintkissecon -- could you attempt to export it into PMDB format (using SpaceClaim) and import it in PyMechanical? PMDB shares NamedSelections and they should be readable by Mechanical AFAIK

Hi @RobPasMue, thanks a lot for the help, now the NamedSelections are transferred. However, I could not export it from Spaceclaim, I had to transfer it to Mechanical, then export from there by hand. Is there another way to do this? My goal is to create a fully automated process, starting from a geometry with named selections, then PyMechanical for the model build-up then PyACP.

I would recommend you have a look at PyAnsys Geometry to do all this programatically. PyAnsys Geometry allows you to connect to SpaceClaim/Discovery/GeometryService. Have a look at this example https://geometry.docs.pyansys.com/version/stable/examples/03_modeling/export_design.html

It shows you how to export to a certain export format -- in your case, you would be interested in PMDB.

So, basically, if you have a Geometry file, in SCDOCX for example, you can import it using PyAnsys Geometry, export it to PMDB and pass it over to PyMechanical. Or you can do your full geometry design directly in PyAnsys Geometry as well if you want (like in the example) and finally export it to PMDB.

Worked perfectly well, thank you very much @RobPasMue!

Glad to hear that!
