Prepare PTX geometry for JT
The PTX-to-JT route uses the PTX reader, mesh preparation and the JT writer. Choose the geometry and representation required by the destination application.
Read the PTX 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.
Build a JT visualization model
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.
Use the OCAF-to-JT converter for supported hierarchy, names, colors and mesh representations. Configure tessellation and any required levels of detail around the viewing task. This output route creates a visualization representation; it does not promise Parasolid BRep export inside JT.
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.
Select a JT version accepted by the recipient and check part positions, geometry coverage and appearance there. Compare both the full assembly and selected parts. If later processing requires precise CAD surfaces, retain the source BRep alongside the visualization derivative.
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.
