It looks like a cut-list for weldments doesn't recognize a right-hand cut from a left-hand cut. i.e. if you make a cut list of a 3 piece "U" path, the left and right parts are said to be identical parts (which they are not if you are using a non-symmetrical profiles like an angle or C-channel). Sure, the 2 pieces are both cut 45-angles but not the same way. Is this a half-baked tool or am I missing something? Thanks.
