[Sheetmetal] Points on a wall and unbend

Hi all,

Here's a problem I have on sheetmetal. I have drawn a sketch containing points on a wall. When I unbend the points remain in the same place and don't follow the wall.

The problem is that I have welded studs constrained on this points, and I would like to do a drawing for the workshop showing the welded studs on the flat part.

Any idea ??

As a workaround, I think of doing a second sketch on the flat part and assemble the studs on it...
