See the attached video. The 3 green curves were just made with the “Adjustable curve blend” tool and have perfect G2 continuity with the white curves. Once I try to create a single pipe using the “Pipe” tool and its “SelectChain” option, Rhino fails to select all the curves.
However, if I run the '_SelChain command outside the “Pipe” tool, then it works as expected and selects the entire loop of curves. It seems like there is a bug in the “SelectChain” option of the “Pipe” tool.
