The BREP: The most important thing about surface and solid modeling that no one ever seems to talk about

Nov 19, 2025, 10:30 PM – Nov 20, 2025, 12:30 AM (UTC)

SOLIDWORKS User Group of New York City

If you’ve been around SOLIDWORKS modeling for a while you might have heard a passing reference to the BREP.  But what is it? This session is going to describe the BREP (Boundary Representation Model) using easy to understand language and examples.  Ed Eaton will talk about the 3 face types (analytical, algorithmic, and ruled) in a way that explains all sorts of weird things you’ve been seeing when using SOLIDWORKS. We will explain terms like “topology” and “Boolean” and why that drives some of your successes using surface modeling where modeling exclusively in solids fail.  Ed is going to show some weird and WILDLY useful exploits made possible by understanding the BREP.  This is a fun, VERY important peak under the hood of every model you have ever created that will educate you on how to solve problems and help the models you make in the future be better.
