I have attached some screenshots. there are wireframe screenshots as well to show the overlapping vertexes.
There is a way i can merge these vertexes in blender, but it breaks normals.
Probably having merge function in moi3d would help a lot.
Hi Toha, those vertices are generated so that the mesh is "watertight" and has a unified vertex structure along edges where the original NURBS surfaces are glued together.
It's a normal part of the current meshing method.
Some previous discussion here on how mesh vertex alignment works:
