https://forums.autodesk.com/t5/inventor-forum/rolled-tube-in-sheet-metal/m-p/5541042#M383326 <P>Either one works, with the Rip being a sheet metal command the ends/almost join point will produce a proper "square" end when unfolded. Both will take about the same time. Yours will take more time in the sketch while the Rib method, more time will be spent at the Feature level. This Rib method also works on cone shapes as well.</P> Sat, 14 Mar 2015 16:12:36 GMT blair 2015-03-14T16:12:36Z
