Are these NURBS surfaces?
Yes

Is there any naming convention for the components?
In solidworks, everything does have some sort of name but it doesn't seem to export with the iges file type. I may not know how to check that though.

What does your outliner look like?
I think you're asking me what it looks like when I click a surface in maya? If so I am giving you some images below.



I'll give you a few screen shots to show you what I'm dealing with, including my export settings from solidworks.

This image shows where I have clicked to select several surfaces, I've used shift to do so. I was clicking on the finger to the right and it selects surfaces across all of the fingers.


This image shows what I get when I "assign material to selection". (I accidentally deselected my surfaces so the selection is slightly different in the images but its the same general idea)


This image shows my solidworks settings when I save as an iges. Also, to the left of the save settings you can see some of the parts from the solidworks assembly, as how they are named and whatnot.. you may or may not want to see that.



Thanks for taking the time to try and help me
