Merge Faces Tool

The Merge Faces tool replaces two or more neighboring faces with a single new face that closely fits the original faces. Use this tool to simplify a model before you export it for analysis. Merging faces can result in a smoother mesh on the solid.

You should only merge faces that are tangent or close to tangent, otherwise, the results may not be what you expect.

You cannot select edges when using the Merge Faces tool. You should use the Fill tool on the Design tab when you need to select an edge and a face to fill in a missing face. The Missing Faces and Gaps tools on the Prepare tab also perform this function.
