Split Surface: How Does it Work?

In response to last week’s post on Cleaning Up Topo Edges, several people pointed out that this could also be done with Split Surface. Using Split Surface hadn’t even occurred to me, since I so infrequently use it. There is usually no reason to split a Toposurface, but this seems like an obvious and practical use of the Split Surface tool.

After testing it out, it does indeed work for cleaning up an edge and it keeps the contours and triangulation the same. But if you know how Topo works, then Split surface must be adding some points along the edge of both surfaces (otherwise the contours and triangulation would not be maintained). Continue reading
