🐞 Description of the bug

When importing a Catia CATPart containing surfaces, meshing a specific surface and export that mesh to a CDB file, the exported file has a lot of unconnected nodes (seemingly from the other unmeshed surfaces in the model). That creates unnecessarily large cdb files. I would like to be able to only export the nodes connected to the mesh.

📝 Steps to reproduce

I am using the following:

import_params = prime.ImportCadParams(
model=model,
cad_reader_route=prime.CadReaderRoute.SPACECLAIM,
length_unit=prime.LengthUnit.MM,
part_creation_type=prime.PartCreationType.BODY,
)
file_io.import_cad(file_name=str(filepath), params=import_params)
surfer = prime.Surfer(model)
surfer_params = prime.SurferParams(model=model, constant_size=20.0, generate_quads=True)
export_params = prime.ExportMapdlCdbParams(model=model)

part = model.get_part_by_name(part_name)
surfer.mesh_topo_faces(part.id, topo_faces=part.get_topo_faces(), params=surfer_params)
file_io.export_mapdl_cdb(str(export_path), export_params)
