OCCT conversion workflows

3MF to JT

Convert 3MF to JT. Prepare source geometry, select the target writer and verify placements and supported attributes.

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

Read 3MF for JT output

A 3MF-to-JT workflow connects the 3MF reader to the JT writer. Select the model items and output representation needed by the receiving application.

Read the mesh content available through the Assimp integration from the 3MF input. Inspect the imported object structure and appearance before constructing the target document.

Build a JT visualization model

The Assimp integration provides mesh geometry, colors, materials and scene structure for its supported inputs. Pass that data to a separate OCCT or commercial writer. For STEP, STEP XML or DXF output, use the mesh-capable representation; this does not reconstruct BRep surfaces from polygons.

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.

Check the JT result

Check the geometry and placement of each imported item. Manufacturing settings and process-specific information require separate validation and should not be assumed to survive a geometry exchange.

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.

Discuss this conversion with the producing and receiving applications, representative files and required geometry and attributes. Compare the reader/writer catalog when a different representation is needed.

Build a 3MF 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.
