Siemens Digital Industries Software releases Parasolid v33.0. The update features a range of enhancements with an aim of extending complex classic functionality to operate on mixed models as the Convergent Modeling paradigm becomes core to its technology.

Enhancements delivered in Parasolid v33.0 include:


A number of classic modeling enhancements are delivered including:

  • improved creation of neutral sheets from pairs of faces with varying offsets;
  • improved solid sweep quality when defining lathing operations, by specifying sections of the path to spin around a supplied turn axis;
  • general transformations, including non-uniform scaling, can now be applied to all body types including general bodies;
  • region control in general booleans allows fine control over which topologies are retained, target or tool, when solid regions overlap;
  • classic sheets can now be extended to a target that contains facet geometry; and
  • returning the minimum distance between transformed input entities without directly applying transformations to the entities.

Modeling with Mixed Models

Several classic operations are extended to operate on mixed geometry, including:

  • replace any combination of classic, facet, or mixed faces with a classic, facet or mixed sheet;
  • replace the surfaces of faces with surfaces containing mixed facet and classic geometry;
  • transform, replace and patch collections of mixed faces in face change operations;
  • project collections of curves of mixed geometry categories along a supplied vector;
  • project onto bodies and faces with mixed facet and classic geometry; and
  • supply face-face and face-edge matches in Boolean operations involving or resulting in mixed models.

Blending Mixed Models

More complex blending operations and configurations are now supported for mixed models:

  • notch blend with constant radius;
  • a mixture of classic and mesh faces may be used when blending three edges at a vertex;
  • smooth overflows between classic and mesh faces are now supported;
  • chains of mixed classic edges and facet edges are supported for apex range chamfers; and
  • deleting chains of blends with blend surfaces of mixed geometry and/or unders of mixed geometry.
