Flatten Sheet Metal With Extruded Cuts

HI All!

I am trying to create a curved circular plate in a sheet metal format. This is so I can then flatten the shape which will show the profile to be cut. It then gets welded to a circular shell.

Attached is how I have been trying to do it but I have got stuck when it comes to flattening the plate.

We have several standard sizes we use so I would like to make configuration for these sizes.

Any help would be great!!!

Thanks in advance,

Jonno
