Read STEP for OCCT BRep output
A STEP-to-OCCT BRep workflow connects the STEP reader to the OCCT BRep writer. Select the model items and output representation needed by the receiving application.
Read STP or STEP files with the OCCT STEP reader. STEP supports precise BRep and mesh representations, along with assembly structure and supported attributes through the XDE document workflow.
Store imported geometry as native OCCT shapes
Inspect the selected parts before choosing their output representation. Preserve BRep for a precise-geometry writer; reuse suitable source meshes or tessellate the CAD surfaces for a mesh destination. Keep assembly placements associated with their parts.
Write the imported precise shapes using native OCCT BRep storage. This route is useful for retaining translated geometry for subsequent OCCT modeling and analysis. It requires BRep source geometry and does not recover analytic surfaces from a mesh-only representation.
Check the OCCT BRep result
Check the STEP representation, unit scale, names, colors and required attributes. A source file containing tessellated data does not necessarily contain the analytic geometry needed for subsequent solid modeling.
Read the BRep file back with the intended OCCT delivery and compare shape types, tolerances and geometry coverage. A standalone BRep file does not carry the complete XDE assembly and attribute document; choose XCAF storage when that document-level information must be preserved.
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.
