Repairing a meshed object

Well I have a complex form that is a mesh. I don’t have access to a nurbs version of the object. The mesh has one face missing so I drew an object to patch it. How do I join the surfaces together to make one valid surface? Much thanks.

PatchSingleFace or FilleMeshHole should do it.


Have you used Triangle Mesh Completer? I saw it on the resources tab, but I was hesitant to download and try for fear of getting a virus. Do you think it is safe to try?
