Maya extrude issue

TXVinylJunkie

When I'm making extrusions with Maya, I always see an extra poly inside the mesh and it also causes the verts to break into two's. I have to go in and merge the verts and delete the unwanted poly on the inside. Is there a fix for that. Here's what I mean:

I guess it was a stupid question to ask; oh well. Gracias por nada.

There no such thing as a stupid question, it's probable that people haven't understood what you are saying.

You probably have Keep Faces Together set to "Off" in your channels after you extrude.

Or if you're using the Modeling Toolkit there's a check box for Keep Faces Together

Run the cleanup utility and get rid of non-manifold geometry, and weld all vertices with a small value threshold before extruding, to make sure there are no overlaps.

It also may have happened if some of the surrounding shapes have different normal directions. Normals>Conform if this is the issue.
