Parasolid V26 released

By Design Engineering Staff   


3D kernel update includes CAM, G2 blend, and surface modeling improvements.

Siemens PLM released Parasolid version 26.0, including enhancements to the kernel’s modeling, blending, surface modeling and wire and sheet modeling.

Enhancements have been made to the handling of matched topology in local and global Booleans. Parasolid now provides fully-automatic matching of nearly coincident regions between the target and tool bodies. The application can specify a tolerance bound for the coincidence test or can select a suitable value.

A body can now be created by sweeping a tool body, locked in a defined orientation, along a 3D path. This is particularly useful for modeling tool paths in CAM.

The yellow cylinder is swept along the 3D path locked in the direction of the vertical arrow to give the blue swept body.

Edge blends can now be created with the requirement that they are curvature continuous with their underlying surfaces. Enhancements have also been added to resolve self intersections in G2 face blends.


Non G2 Blend (left) and G2 Blend (right)

Surface Modeling
When creating a surface to fill a hole, the usual G2 requirement may be relaxed in areas where the existing geometry makes it impossible to fit a G2 surface. This is a common case when importing data from other systems.

The surface to the left of the hole has a non-G2 smooth edge.

Wire and Sheet Modeling
Wire bodies may now be split or knit whilst retaining edge tags. Control is also provided as to whether internal loop of faces are sewn up. This gives developers extensive control of behavior.

Orange input edges become one resultant body and blue edges become another resultant body.
