Sheet metal form revolve to flatten

Hi All,

I have a problem that should be stupidly simple, but I seem to be stuck.

Essentially, what I am hoping to do is create one sheetmetal face, revolve it and then flatten so it can be lasercut.

Attached is an example of the form, but I seem unable to have the faces join to allow it to flatten.

Again, apologies for posting something that should be simple, and thanks in advance.

Brad
