Im doing some multibody training and got stuck on one sketch that wont create base-flange with the message "The sketch has both open and closed contours."
So how come it will extrude-thin?
And why am I allowed to do what I can understand is much the same on the axle Support?
The body in question is the last feature to be the tongue support, made as an extrude-thin.
File is SW2012..
