Can anyone help with this??

I am working with an imported .IGES file converted from Pro-E (Wildfire 5.0).  I have been trying to run the FeatureWorks Tool to define most of the features, and I'm running it 'Interactive' rather than 'Automatic' because I was not getting the results I wanted.

I was successful at recognizing a few Holes and Cut Extrudes, but I am having major trouble with the Fillets and Slotted cut-outs.  (see attached photos)

It is an oddly shaped part and all of the edges are filleted.  I have tried to use the 'Cut Extrude' feature to recognize the Slots, but no luck...

Does anyone have any suggestions??

Thank you!

Regards,

Hillary
