Create sharp dimple with Sheet Metal Forming in Wall?

Post by anthonyg »

In Sheet Metal workbench I'm trying to create this sharp dimple using the Forming in Wall tool:

With Forming in Wall tool it seems that it only accepts a face of the forming tool, then it places the face perpendicular to the sheet metal face and performs the operation.

I tried using a cylinder to perform this, but can't rotate the dimple afterwards for it to look as desired.

I also tried creating a face in the cylinder and use it, but I get an invalid shape:

it's wrong with Sheetmetal, it'll edge you with an R= to the thickness
you have to make a Pad with a sketch at 30°, a Pocket with another, then surface what is left
