I seem to have a problem when creating new edges and faces on a mesh. When I turn on subsurf after creating them Blender always draws the faces differently to what they would be if modeled with basic mesh modeling (extruding, scaling, grabbing).
On this particular model I want a nice smooth tube, but I needed to change it slightly. Once I’d created the new mesh and turned on sub-surfacing the tube was all contorted and looked totally different, even though the mesh was the same as before. Except it was in a different place on the mesh.
Hmm not sure I explained it too well. Is there any way around this problem? I’ll get some pictures up if people don’t understand what I mean.
