Hi, I am using SolidWorks 2015 and I have come across a very annoying problem.

I have modelled a "weird" cone and planning to cut it from a steel plate. For this I need the flat pattern, however I am unable to convert it to sheet metal or insert any bends due to my "fixed edge" not being linear.

I have attached the file for you to see. The cone is exactly the way I need it, I can not consider any other designs or linear fixed edges..

If anyone could suggest me a way to convert this to Sheet Metal or, if you will, model it using sheet metal, I would be grateful.

Thank you for your time.
