Parasolid v34.1 release highlights

Parasolid v34.1 delivers enhancements across a wide range of classic, convergent and lattice modeling functionality to address the needs of our diverse customer community. These include:

Lattice Modeling

Support for lattice modeling is being extended significantly with each release to facilitate more workflows:

  • Rods of different radius are now permitted in the same model
  • When combining lattices, several options are provided to keep or delete coincident rods
  • When combining lattices, an option is provided to snap near-coincident balls together, within a specified tolerance
  • Facet meshes creation from self-intersecting lattice bodies is improved to handle the resulting disjoint meshes

Modeling

Classic modeling enhancements are delivered including:

  • In mid-surfacing operations, neutral sheets can now be created from faces in two sheet bodies, removing the restriction that faces must be from a single solid
  • When offsetting an edge to fill a gap with an adjacent model, creation of a natural curve extension can now be specified, to avoid creating non-smooth offset edges

Modeling with Mixed Models

A small number of complex, classic operations continue to be enhanced to operate on mixed geometry, In this release enhancements include:

  • Local hollowing, hollowing a portion of a model, can now be performed where the portion of the model contains both B-rep and mesh faces
  • Wounds created in a model by deleting one or more faces, can now be healed by growing and shrinking both mesh and classic neighboring faces
  • Mesh faces can now be used in Boolean operations to match topology

Blending Mixed Models

Complex blending operations on mixed models have been enhanced to improve robustness is downstream operations, including:

  • Notch overflow blend operations on mixed geometry now create better quality mesh faces
  • Face-face blend operations now create better quality cap faces when extending mesh faces
