Geometry abstraction, polygon geometry, and convergent geometry > Modifying polygon edges
Merging polygon edges
Use the Merge Edge command to merge two polygon edges together by removing the vertex between them. Merging edges is useful, for example, when you want to create a more continuous boundary edge prior to meshing. You can also use the Merge Edge command to recombine edges that you had previously divided with the Split Edge command.
Note:
You cannot use the Merge Edge command to combine edges when more than two polygon edges intersect at a single vertex.
Merging edges based on vertex angles
You can use the Vertex Angle option in the Merge Edge dialog box to merge edges in a model based on the vertex angle between those edges.
The Vertex Angle is the angle between two separate edges that are joined at a vertex along the boundary of a face, as shown below.
The software remove a vertex between two edges when the angle between those edges is less than or equal to the specified Vertex Angle value.
