The operation merges opposite edges by collapsing the face between the edges. The edges selected to be removed are merged with the edges to be kept, and the faces adjacent to the removed edges are reconnected to the resulting merged edges. This is shown in Figure 7-32 and Figure 7-33.

Sliver and small faces can require a very fine meshes size, which can create meshes with many mesh elements. The Merge Edges, Collapse Faces, Form Composite Faces, and Ignore Edges operations provide a manual way to remove sliver and small faces, while the Remove Details operation is a fully automated way to prepare a geometry for meshing.

To use the operation, in the Geometry toolbar, from the Virtual Operations menu (), select Merge Edges (). Then enter the properties of the operation using the following sections:

Select the edges that you want to keep in the Graphics window. They then appear in the Edges to keep list.

Click the Active button to toggle between turning ON and OFF the Edges to keep selections.

Select the edges that you want to remove in the Graphics window. They then appear in the Edges to remove list. Click the Active button to toggle between turning ON and OFF the Edges to remove selections.
