Solid Edge. Design better.
Doug Stainbrook
Background:
I am the team leader for the Solid Edge Field Support Team. This group is
the technical resource for supporting Solid Edge pre-sales activities around
the world. Before coming to the Solid Edge team, I spent about 10 years as a
designer for various industries. In 1999, I was hired as
a Solid Edge Application Engineer in Philadelphia, PA.
In 2000, I came to Huntsville, AL, to the home of
Solid Edge to work in the Field Support group.
Areas of Expertise:
Synchronous and ordered part and
sheet metal modeling
Personal interests:
Photography, art, high-speed engraving, and
website design

Executive Summary
Today’s Topics:
In this Solid Edge hands-on training session, we will take a look at new and
exciting synchronous features and modeling techniques included with Solid
Edge ST4, which will make creating and editing your parts much easier. New
synchronous commands have been added, and many have been enhanced
to make them more streamlined and user friendly. We will work through
several step-by-step exercises covering how some of these new commands
work and when and where you should use them.
Key Takeaways:
A greater understanding of and confidence in synchronous part modeling
