Prepare PSL geometry for STL
The PSL-to-STL route uses the PSL reader, mesh preparation and the STL writer. Choose the geometry and representation required by the destination application.
Read the PSL scan data through the point-cloud interface. Select the scan region needed by the destination, establish units and alignment, and inspect sampling density and missing areas before constructing a surface.
Write the selected surfaces as STL triangles
A surface-mesh destination requires face connectivity, not just point positions. Reconstruct the required surface from the imported points, then tessellate it or prepare the resulting polygonal mesh. Surface from Scattered Points provides a surface-fitting workflow to evaluate for this preparation step.
Prepare triangulation for the selected geometry and write it with the OCCT STL interface. Set mesh detail for the destination task. STL does not retain the full assembly tree, names, colors or CAD metadata; keep the source model when those relationships matter.
Validate the converted model
Compare the reconstructed surface against the scan, including gaps, noise and sparse regions. Specify fitting tolerances and how boundaries or missing areas are handled. The mesh is a derived surface whose accuracy depends on the source samples and reconstruction settings.
Check unit scale, bounds, face orientation and connectivity in the receiving application. Include small features and curved regions in the comparison. Producing an STL file does not itself validate printability, watertightness or suitability for material removal.
For repeated jobs, retain the source, preparation settings and representative output checks. Discuss this conversion with the input files, destination application and required geometry and attributes.
