Require some assistance. When trying to cope a weldment union of a 12" pipe and a bigger 16" pipe, the 12" pipe continues to stick into the 16" pipe as shown in blue. How can I trim off this blue bit that's inside and get a nice clean cope at the interface of the two ? Currently I have the sloping 16" pipe and the straight 12" pipe as two separate sketches, to which I have applied two weldment profiles. I'm guessing there's more than one way to do this, I'm looking for the best and easiest way. Once coped, I'd like to define a 6mm weld bead at the joint Thank you.
