How to Fix Zero Thickness Geometry in SOLIDWORKS
One of the most common modelling errors faced by SOLIDWORKS users is the Zero Thickness Geometry error. Many designers know how to avoid it, but only a few understand why SOLIDWORKS shows this error and what it really means for the model. In this blog, we will break down: What Zero Thickness Geometry actually is Why SOLIDWORKS does not allow it And finally, three simple ways to solve it Zero Thickness Geometry (also known as non-manifold geometry ) happens when two solid features in your model touch each other only at a single edge or a single point, without sharing a real volume of material. A valid solid body in SOLIDWORKS must follow one strict rule: Every edge in a solid must have exactly two adjacent faces. If an edge has: · Only one face → invalid · More than two faces → also invalid · Features touching only at a point or line → non-manifold → e...
