OCCT conversion workflows

STL to JT

Convert STL to JT. Build JT visualization meshes with supported names, colors and assembly placements.

Build this conversion into your application with OCCT readers, writers and the commercial components identified below.

Read STL for JT conversion

A STL-to-JT workflow combines the STL reader with the JT writer. Use it when the receiving application needs JT data from an existing STL model.

Read the STL triangulation through the OCCT interface. Treat it as surface geometry: the source does not provide a full assembly tree, CAD names, materials or precise BRep surfaces.

Build a JT visualization model

Transfer the existing triangles into the target mesh representation. If the destination needs names, colors or a scene hierarchy, author these in the application rather than claiming they were recovered from the STL.

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 JT result

Agree on unit scale and check bounds, face orientation and connected regions. Repackaging a coarse or incomplete STL does not improve its geometric accuracy or establish manufacturing suitability.

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 a production pipeline, keep a representative source file and its expected geometry and attributes with the conversion settings. Discuss conversion integration with the source and destination applications, or compare the supported format interfaces.

Conversion integration

Build a STL to JT workflow

Share the source and receiving applications, representative files, required attributes and throughput. We can scope SDK evaluation or an integrated conversion service.
