Creating highly detailed production-ready components is something SOLIDWORKS excels at, but not all of this detail is required in higher level assemblies. The Defeature tool provides the capability to massively remove unnecessary detail to improve large assembly performance or to protect intellectual property.

SOLIDWORKS 2019 introduces a new Silhouette option to help simplify an assembly based on the outlines of components and bodies

We will start by selecting several components that we would like to retain their original geometry, in other words, no simplification. A variety of simplification methods are available; for this selection, we will choose no simplification to copy the geometry. As we add this group, SOLIDWORKS splits the window and presents a preview of the simplification. The view orientation of the windows, stay in sync to help visualize the progress.

Next, we can use the new option to Select Identical Components and assign different outlines like Cylinder, Polygon and Tight Fit Outline according to our requirement.

Once satisfied with the simplification, the Defeatured model can be saved to a new document with a “Link” to the original, or component suppliers can upload directly to 3D Content Central to be shared on the web with millions of designers and engineers.

This defeatured model is much better suited for the top level assembly.

Simplifying complex assemblies has never been easier than with the enhanced Defeature tools in SOLIDWORKS 2019. This tool will help users share their models and protect their intellectual property.
