Weldment Protrusion

Hey guys,

I'm having trouble with structural members protruding into each other and I don't recall this happening in the 2008 version.

Even if I uncheck the 'Allow protrusion' option in the settings, I can see the cross section of each member protruding another member.

Suppose I want a rectangular base frame of angles - I draw the rectangle in a sketch and select the sketch in the design tree to define the path. Should I be doing it another way?SolidworksWeldments
