Hello all,

I'm  trying to extrude cut the sketch in the attached file..

I've tried multiple ways to select the contours i want to cut but it was never cut as I wanted it to be cut, so I tried to select the sketch itself but it gave me the following error:

"

The sketch contains a doubly nested contour.

Pick a sketch entity to define an open or closed

contour. To define a region, pick inside an area

bounded by sketch geometry.

"

I dont know what a doubly nested contour.. and in general what i need to do is to cut the white areas in the wolf to leave only the outlines.. Can anyone please help me??
