in the current workspaceSplit a face to add more definition to an area without having to refine it. Because you specify the start and endpoint of the split, this method provides greater control over the location of the split.

For more precision in the placement of the split, you can specify that the split starts or ends at a vertex. The Vertex option is useful for creating two triangular faces from a rectangular face. It provides the precision you need if you later want to spin the new edge using MESHSPIN.
