Supported File Types for Import and Export
You can open and insert files from other modeling applications, and you can save your designs into different file formats. If you insert a model while another is open, the material data from the second model is not imported.
For more detailed information than what is provided here, see the CAD Integration section of the product help or the Platform Support section of the Ansys Website, where you can view the CAD Support PDF for your release.
