Hi all.

I am working in SW 2017 at my workplace.

I am making sheet metal conic filter that looks like a pointy hat.

When i make only conical part i can get Folded sheet metal From of it. But when i add metal flange = ring part around it (base of cone- circle).....Folded pttern is impossible to achieve. I tried to do this conical sheet metal part in 2 different ways following some tutorials on the net.

As a Revolve feature drawn narrow line around a center-line and then converted to sheet metal.

As a Swept Flanges.

It should look like on the image below without plate that holds it.

I can't achieve Flat pattern from of it. This is very important to be Drawn in with correct dimensions in order to produce it.

Thank you very much for your help.
