Merging faces

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 can't select edges when using the Merge Faces tool. You should use the Fill tool on the Design Closed 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.

The merge faces tool is only intended to be used as preparation for analysis. Merging faces simplifies the model by removing edges and makes the model more difficult to modify.

To merge faces

Click Merge Faces in the Adjust group of the Repair tab.
Select two or more faces you want to merge.
If you want to retain tangency between the new face and an existing face, click on the Maintain Tangency tool guide and select the face with which you want to retain tangency.
Click the Complete tool guide.

Discovery SpaceClaim replaces the selected faces with a new face.
