0033099: Data Exchange, Step Import - Wrong PMI values in GDT measure_with_unit entity is changed to be translated as Handle(Standard_Transient) and to be processed later, depending on the underlying type being used. 0033484: Data Exchange, Step Import - Pretessellated geometry is translated incompletely Added proper translation for TessellatedCurveSet and ComplexTriangulatedSurfaceSet. 0030024: Data Exchange - STEP, IGES export support of BRep shapes based on tessellated geometry Support of reading and writing tessellated geometry is added for the following STEP entities: - triangulated face - complex triangulated face - tessellated shell - tessellated solid - tessellated shape representation Models without BRep geometry (mesh formats like STL, OBJ and so on) are supported for writing to STEP. New parameters are added to enable/disable tessellated geometry reading and writing: - read.step.tessellated (On/Off/OnNoBRep) (On by default) - write.step.tessellated (On/Off/OnNoBRep) (OnNoBRep by default) OnNoBRep - tessellation is read/written only for entities for which there is no BRep representation. Faces with poly triangulation are written in STEP as triangulated face entities with one coordinates list per face. Only one poly triangulation per face (returned by BRep_Tool::Triangulation) is written to STEP.
