sorry folks, didnt know what else to call it. i'm sweeping a circular profile along a curved path.. sort of like a long curvy pipe. in fact, *exactly* like a long curvy pipe. this is hypothetical, it won't be fabricated, but if it were, it would be made of curved pipe segments that are bellmouthed at one end.. so one tube/pipe can fit in the next. how can i model the bellmouths every, say, 20' along the path? do i have to model this piece by piece? (this does not need to be an assembly) tips? thanks, -tony
