Import Geometry

Workflow tips for geometry import in SimSolid.

  1. Use Parasolid reader for best results.
    • This reader only brings in solid geometries ignoring other data.
    • Parasolid files is preferred over step files.
    • With NX, use native geometry files.
    • With CATIA, 3dxml files are lighter and faster to import.

  2. If you are using the legacy reader, be cautious:
    1. Access legacy reader by unchecking ‘use Parasolid reader’ option from geometry import settings.
      • Legacy reader repairs the geometry during import.
      • It works well if there are small gaps/overlaps in the geometry, can use HyperMesh/Inspire to check.
      • Repair functionality can fail in other cases resulting in bad geometry.
  3. Always export geometry in assembly/global coordinates, so they are positioned correctly.
  4. If part instances exist, save a copy of the part that can be imported into SimSolid.
