Noobie Maya modeling tip...

... for the one person other than me that didn't know it.

If you made a model with a hole and went ahead to seal it with Mesh --> Fill hole and it wouldn't do it, then you have messed up normals in your model. Select your model, click on Display --> Polygon --> Face normals to view your normals. Then select the faces with the reversed normals and go to Normals --> Reverse. Now fill up that hole.

Maya tip (possibly for other 3D modelers as well)

Made a 3D model that has lots of angles and or complex geometry that makes it hard to select elements?

Or you need to move around your model a lot to select the edges or vertices that you need?

Well if you have made a proper UV map, just load the UV editor window and select away. Easier to do so in there for lots of elements because of the unwrapped model.

Pictured above: Simple model of an ogre's club. The edges were selected in the UV editor; since all the teeth had their UVs overlapping each other's to save texture space, selecting the edges took a couple of clicks.
