Parasolid v32.0 Release Highlights

By PeterKerwin

Parasolid v32.0 delivers support for Convergent Modeling™ on models containing a mix of both facet B-rep surfaces and classic B-rep surfaces (mixed models), in addition to enhancements across a broad front of established functionality.

Convergent Modeling on Mixed Model

Convergent Modeling now operates on models containing a mix of facet B-rep surfaces and a subset of classic B-rep surfaces. This subset includes classic analytic planes, cylinders and spheres. So, for example, a fully facetted model may now be Booleaned with classic B-rep cylinders to create through holes or sectioned with classic B-rep planes, each creating new classic B-rep surfaces in the model. This first implementation of Convergent Modeling on mixed models opens up new work flows such as restoring precise, classic mating surfaces to a model that has undergone facet-based topology optimizations. Similarly, precise analytic surfaces can be added to scanned data of a part for re-manufacture.

Blending and Chamfering

  • On creation, the size of an apex range chamfer is checked, and diagnostic information is returned if it is too large for the surrounding geometry.
  • Diagnostic information is returned if overflow or capping has extended an apex range chamfer beyond its natural width.
  • Face-face blends are now possible on configurations where multiple blend faces need to be joined by extending a common capping face.

Booleans and Surfacing

  • A new option is added to provide tracking information for new regions created during Boolean operations, allowing each region created to be traced back to its originating region.
  • A new type of clamp can be specified when applying derivative conditions to lofted bodies. Composite clamps combine vector clamps and face / planar clamps providing control of the flow lines of the loft in the tangent plane of the clamping face or plane
