Parasolid version 28.1 release highlights

by Community Manager Community Manager ‎05-18-2016 12:26 PM - edited ‎01-31-2017 06:05 AM

Parasolid v28.1 is the first in a series of releases to deliver convergent modeling, which brings facet modeling and world-class B-rep modeling into a single, high-productivity architecture. Convergent modeling will enable Parasolid customers to develop applications that deliver more efficient PLM workflows, for example reverse engineering and Computer-Aided Engineering (CAE). This major innovation is complemented with our regular release of enhancements to B-rep modeling, providing customers with the most comprehensive and robust set of modeling tools in the industry.

 

Facet Modeling

 

Parasolid v28.1 includes the first installment of Parasolid’s convergent modeling technology and enables facet models to be created and modified in Parasolid using a large selection of the established functions used on classic B-rep models.

 

Applications benefit from the ability to deploy a common set of familiar modeling tools, regardless of the geometry format, using a single geometric modeling component. Supported operations include Booleans, sectioning , hole-filling , hollow/offset/thicken , rendering , faceting output , read and write XT, data import and export , checking and repair , imprinting , sheet trim and extend , swept and spun outline , extrude , topological and geometric enquiries , mass properties , min/max distance (closest approach) , clash detection and topological and geometric enquiries.

Model Editing

 

Parasolid v28.1 includes a number of enhancements to increase control of detailed modeling operations:

 

  • Improved generation of isocline surfaces during tapering operations and improved diagnostic reporting when tapering cannot be performed exactly as specified.
  • Improved diagnostic reporting in body extension operations when edges cannot be extended exactly as specified.
  • Improved control is provided over the geometry of laminar edges during patch operations.

Surface Modeling

 

Parasolid v28.1 provides a number of enhancements for sophisticated creation and editing of surfaces, including:

 

  • Added ability to break geometry sharing between the faces on a surface, when re-parameterizing faces.
  • Added ability to produce degree 1 B-surfaces from a lofting operation.
  • Improved quality of clamping with guide wires when lofting.
  • Improved stability of constrained surface solutions for small changes to the input geometries.
  • Improved swept tool operation now accepts a target body and Boolean operations for the swept volume created.

Other Enhancements

Numerous other enhancements have been made over a wide front of functional areas, including:

 

  • Improved ability to create constant radius face blends and variable radius edge blends on tightly curved faces.
  • Improved General Modeling allows body extension across a set of laminar edges on a body so long as they are locally manifold.
  • Improved General Modeling allows locking of a sweep using faces from a general body, so long as those faces are locally manifold.
  • Simplified version mechanism provides a single entry point for setting versioning, using a single API call.
  • Extended Symmetric Multi-Processing (SMP) increases performance when calculating the distance between two bodies.
