Does thsi seem right? I just downloaded this autocad file off T3flange.com of a B series header flange and it seems a little messed up to me. I wouldnt really know so im hoping you guys can help. Are all the holes along the bottom supposed to be out of line?



If anybody know the right dimensions could you help me out a little.

Thx

They seem to be in line with each other
