Sheet Metal RIP error when 2 ends of tube have been CUT

[modfox]

Basically a 2.5" id tube with a .06 wall thickness - 16ga exhaust tubing. Once I finaly got the drawing right, I cannot rip the part. The part has both ends cut. If one of the ends is left un cut I can create a sketch and put a point where I want to rip, and successully rip the part. If both ends has a cut end has a cut, there is a RIP error. How to overcome this headache? I am trying to make a template which If i can rip the part, I will be able to do so.

using autocad inventor

Hi Modfox

Please see attached dataset, there is a easy way to achieve your goal, that is add rip feature before cutting, and the part can be flattened.
