Webinar: History-based, Direct and Synchronous Modeling

What designers need to know about the 3 CAD paradigms


There are three modeling paradigms in modern CAD systems:

  • History-based
  • Direct
  • Synchronous

In this webinar you will learn:

  • An understanding of the technology foundations, the strengths and weaknesses of each of the three modeling approaches
  • How does parametric modeling apply in each modeling approach
  • The why and how direct and synchronous modeling were developed
  • The manner in which design intent is captured in each approach

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.


Jeff Walker is Director of Solid Edge Product Development. He has a bachelor’s degree in Mechanical Engineering from Auburn University.

Prior to Solid Edge, he was a stress analyst for the US Army Missile Command using FEA tools to conduct studies of missile systems and related equipment. Jeff has over 25 years of experience in CAD and CAE software.

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