Parasolid v31.0 delivers classic B-rep functional enhancements to support complex workflows, making it easier for developers to code and maintain sophisticated applications with ever greater efficiency. V31.0 also includes many enhancements for creating and modifying facet B-rep geometry and the architectural foundations for Convergent Modeling™ technology.


Enhancements include:


Surface & Sheet Modeling


  • Sweeping is enhanced to support the use of more than three guide wires.
  • Mitred or rounded corners may be specified when sweeping a body along a non G1-continuous path.
  • When creating a sheet body by copying a set of faces from a body, it is now possible to specify that the faces created have the tags of the original body faces.
  • Non-manifold bodies that touch at edges as well as vertices may be knitted together into a single non-manifold body.

Model Editing and Blending


  • When creating a step face with a transform or offset operation, the resulting new face(s) may be kept or merged with adjacent faces.
  • When transforming or offsetting a face or set of faces, geometry can be supplied to define the shape of the step faces created.
  • A rotational surface may be radially offset with respect to its axis of rotation, maintaining the profile shape of the spun result.
  • Notch blends may now be created in configurations where there is overhanging geometry

Mesh specific functionality


  • Faces with facet geometry may be deleted and the resulting wounds capped with facet geometry.
  • A new mesh may be created by combining two or more meshes from adjacent faces on a body.
  • When repairing a mesh, different tolerances may be applied to different types of defect, such as degeneracies, slits and fold-overs.
  • Polylines whose ends lie within a specified tolerance of each other may be snapped together to create a watertight wire body. Parasolid version 31 - mesh.jpg
