Based on our over 25 years experience, CAD Interop recommends below the most relevant CAD formats to convert your data between major CAD systems. To date, the most common exchange format is the STEP format, the most complete and available for the majority of CAD software. But, when possible, it is preferable to use the geometry kernel of the software (such as Parasolid for NX, SolidWorks or Solid Edge) which will allow to read the geometry without translation. If you want to provide read-only access to your CAD data for users who do not have a viewer or other CAD software, we recommend using the 3D PDF format in its faceted (lighter) version.
