Turn a Parasolid export into STL triangles
This route combines the Parasolid Import SDK, a surface mesher and the OCCT STL writer. The reader translates X_T text or X_B binary input into OCCT geometry and topology. The imported shapes provide the basis for controlled tessellation.
Use this route when the sending CAD system exports Parasolid and the next tool expects a triangle surface. The workflow operates on the exchange file; it does not require or imply reading the original application’s native project.
Prepare BRep before meshing
Configure Shape Healing for the source model and inspect the translated shapes. Then select the items to export and set the meshing tolerances. Separating import repair from tessellation makes it easier to identify whether an unexpected surface comes from translation, geometry preparation or the mesh configuration.
Express Mesh provides size and deflection controls. For a closed-shell requirement, check connectivity and orientation after meshing rather than relying only on a successful writer status.
Deliver the intended STL geometry
Specify the coordinate scale expected by the recipient and apply item placements before writing. STL does not retain the names and colors available through Parasolid’s XDE import layer. Preserve the source or use Parasolid to STEP when those engineering relationships matter.
Compare the reopened mesh with the imported shape on representative curved and small-detail regions. Increasing triangle count cannot correct missing or invalid source geometry by itself.
