Webinar: When to Use History-based, Direct and Synchronous Modeling

Which CAD paradigm matches your requirements?


There are three CAD modeling paradigms:

  • History-based
  • Direct, and
  • Synchronous

In this webinar you will learn which of these three approaches best matches certain design workflows:

  • From heavily leveraging existing designs to handling critical last minute changes
  • Dealing with imported geometry from other CAD systems
  • Establishing and promoting design standards and best practices

Your presenters:


Dr. Ken Versprille heads the Design Creation and Collaboration Research Council at the research firm, CIMdata. His research projects have spanned complex geometric design approaches, design collaboration, design automation, PLM standards, and the horizontal integration of CAD across related PLM applications.

Dr. Versprille is recognized for publishing the first description of NURBS (Non-Uniform Rational B-Splines), the mathematical curve and surface formulation that has become an international standard in CAD and Computer Graphics.


Dan Staples is the Vice President of Product Development for both the Solid Edge CAD and Femap FEA software programs at Siemens PLM Software.

Staples has more than 25 years’ experience in the Mechanical CAD industry, including key roles at Intergraph, SensAble Technologies, and UGS. He was instrumental in defining the vision for the Solid Edge product line and managing its deployment and evolution. Staples holds a bachelor’s degree in mechanical engineering from Rice University and an MBA from Vanderbilt University.

This webinar is sponsored by Solid Edge from Siemens PLM Software.
