Session Abstract

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 will describe the BREP (Boundary Representation Model) using easy-to-understand language and examples. I will talk about the three 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 in surface modeling, where modeling exclusively in solids fails. I’m 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, educating you on how to solve problems and improve future models.
