Can a circular tube be made in onshape sheet metal and show up in the flat pattern.

Like a shroud with vent openings.

It seems OS only allows flat sheetmetal faces. That being said, you can approximate a round tube by using a segmented cylinder. See my example below.

Any idea what the limit on segment count may be?  (Either from a coded limit or a performance wall). Can we get so close as to fool the naked eye?

@owen_sparks, I imagine the number of segments would be limited by the bend radius selected. I wouldn't bother with that route, though. More trouble than it's worth. Plus, k-factors are approximations to begin with. If the entire part was just one bend after another, I wouldn't have much faith in the flat pattern.

Thanks @mahir appreciate the explanation.  Cheers, OwS.
