Fair call. Sometimes (Ok - rarely) the IGES import will solidify the incomming model. On the occasion where it does not, you can attempt a repair in Inventors repair environment - but that can take weeks. I would work with the imported surface model. (Actually - Inventor 2013's repair environment is a considerable improvement over previous releases.)
The problem will come later when you create drawings. Surfaces are slower to draw than solids, and by default, surfaces don't actually appear. Right click the model in the drawing browesr tree and check "include surfaces".
Hope that helps.

I see no reason to fool with the IGES (and IGES can be set to save as solid rather than surface), but as I said - I would not fool with IGES, there is an easier way.
In autocad I then exploded everything I could, there seemed to be blocks within blocks.
Any advantages in using IGES over STEP?
The part created will not be modified in inventor, so- a surface model part will be fine for this application.
You mention an easier way? Can you please enlighten me?
