Export a JT visualization representation as STL
The JT reader can supply triangulation at multiple levels of detail. A JT-to-STL pipeline selects the required representation and writes its triangles through the OCCT STL interface. The Parasolid interface is not needed when the JT mesh already contains the geometry needed by the destination.
When the JT file contains embedded Parasolid BRep, the Parasolid interface can import that precise geometry instead. Tessellate the imported OCCT shapes at the required deflection, then write STL. This route lets the application generate a new mesh from the source BRep rather than use a stored JT level of detail.
Use this route for geometry-only delivery from a JT visualization model. Decide whether the export covers the full assembly or a selected set of parts.
Select LOD and apply placements
The chosen level of detail determines the available surface approximation. A coarse JT mesh cannot regain detail by being stored as STL. If the source has a finer representation, select it before export and compare the cost and geometric benefit.
Apply each selected item’s placement consistently. For large assemblies, define whether the application creates separate part files or a combined mesh, and report items without the requested representation.
Check geometry-only output
STL does not retain the JT assembly tree, names, colors, transparency or PMI. Preserve the JT source or maintain those relationships in a separate application record if they are needed later.
Agree on unit scale and reopen the STL in the receiving application. Check surface coverage, orientation and connectivity for the intended process. If the target needs STEP with retained mesh or precise geometry, use JT to STEP and select the appropriate representation path. Mesh preparation and conversion should not be mistaken for validating printability or manufacturing suitability.
