Parasolid V26 released
By Design Engineering StaffCAD/CAM/CAE CAD Siemens PLM
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.
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.
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.
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.
