Geometric development - Pipe elbow- how to get a perpendicular cut on the profile curve

Hi,
I need to produce a flat cut pattern for an elbow meeting a straight piece of pipe.
that part I have figured out and I can get the flat pattern. however, in real world use, I would not be able to produce an infinitely fine taper to join the profiles. I need the pipe face profile to end at the pipe wall thickness.
This is the model

the true profile would be a line with a fixed point, rotating while moving perpendicular to the axis of rotation. I have created a loft that approximates that profile. but I do not know how to use that loft profile to split the part. (strictly speaking the loft profile doesn't look %100 correct either, but it is close enough)
Any help would be appreciated!

Hey Shervin. Perhaps the method in this document is what you are after; not sure. I opted to extrude a surface rather than a solid in the extrude of the straight pipe. A Boolean Remove resulted in a surface with one end having the contour of the elbow. Last was the Thicken tool. - Scotty
