Prepare PTS geometry for OBJ
The PTS-to-OBJ route uses the PTS reader, mesh preparation and the OBJ writer. Choose the geometry and representation required by the destination application.
Read the PTS 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.
Prepare polygonal geometry for OBJ
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.
Write the selected surface mesh with the OBJ interface. Establish whether the consumer needs per-part grouping, normals or supported appearance information, and preserve any associated material resources produced by the writer. A polygon file is not a replacement for the full CAD document.
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 the OBJ in the receiving graphics or geometry tool, including scale, face orientation, grouping and companion-file references. Where a flat mesh cannot retain the original assembly relationships, keep that engineering information separately.
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.
