Can't extrude faces created by loft

[sethkrumm2001]

I have a part that I created using lofts and now I can't select the faces with the extrude tool. All the sketches that were lofted were made from straight lines, so the faces *should* be flat. I exported it as as a .step, imported it, and still have the problem, so I suppose it's an issue with the model's geometry rather than the editor. Any ideas?

@sethkrumm2001 I recommend using the press pull tool which is under modify menu instead of extrude.
If you want to extrude you should project the edges to give that a reference for extruding.

Please understand that extrude asks for profile selection not the face. Where as in presspull you can easily do that without a profile being selected instead we select face to be extruded. These are some direct modeling techniques which are captured as offesetting faces.

The easy way to tell if the face is twisted, (by any amount), is that you can't, 

Extrude the face, sketch on it, or make an offset plane from it.

Not all your faces are twisted.
