Sheetmetal unbend cylinder with profile

[DieselPig]

Afternoon All

Is it possible to unbend a sheet metal cylinder with a profile? I have fiddled with this all day and tried a variety of options with no luck.

The attached picture shows the profile I created when revolving the cylinder. I want to unbend the cylinder to put more sketched forms on it.

Hi Manoj Kumar

Yes I have tried cross section unbend but I could not get it to work. Any help is greatly appreciated.

Some history:

I started off with a plain extruded cylinder and attempted to use a sketched form for the profile but it won't run to the edges.

Then a revolved part as above with the profile but this wont unbend.

You might try a user defined flange. If I am understanding your image correctly, the flange would be along the diameter with the "lump" defined in the flange sketch.

I think the section unfold requires a planar surface:

Hi Antonius

Thanks for that, I did try the cross section tool but I could not make it work.

The flange solution works.

Hi Antonius

Just loaded your part and I see how it's done. Brilliant!

Must admit my ignorance of sheetmetal and it's functions.

Thank You very much.
