OCCT conversion workflows

STEP to JT

Convert STEP to JT with OCCT3D. Prepare assembly hierarchy, names, colors and mesh levels of detail through the document-to-JT workflow.

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

Build a JT visualization model from STEP

A STEP-to-JT pipeline reads the STEP document, prepares its mesh representations and transfers the supported hierarchy and attributes with the JT exchange SDK. STEP BRep surfaces can be tessellated; existing STEP mesh data can also supply a visualization representation.

The documented OCAF-to-JT converter transfers names and labels, colors, hierarchy and mesh data. This route is useful when a downstream system uses JT for product visualization or lightweight assembly exchange.

Prepare levels of detail and structure

Decide which levels of mesh detail the recipient needs and how to generate them from the source geometry. Check part placements and repeated assembly items alongside triangle quality. File size and interaction performance depend on the selected representations as well as the number of parts.

The JT component supports standard compression and provides model access for application integration. Its DRAW examples demonstrate the document converters and can be used as a reference for the selected SDK delivery.

Select the writer version and retained information

The published writer coverage lists JT 8.1, 9.5 and 10.0. Confirm the version expected by the recipient and verify names, colors, transparency and structure in the resulting model.

Do not infer precise BRep export from optional JT BRep import support; those are separate directions. Identify any PMI requirement explicitly and assess the information exposed by the complete route. For reading JT back into a STEP workflow, see JT to STEP.

Conversion integration

Build a STEP 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.
