    Posted: 17.May.2016 at 18:45
Hi Guys,
I'm new to this, so please bear with me. I have been trying to generate conical plate sections with bent flanges so that I can give the client a Flat Pattern of the Plates.
Modelling it is not a problem o show him what it looks like, but I cannot get Inventor to give me a Flat Pattern. I first tried on 2013, and now on 2017. I have not had a lot of Sheet Metal Experience, which doesn't help.
I appreciate that with a cone, everything converges to the apex point, and I think this is one of the problems I am dealing with.
Any help would be appreciated. I don't know how to attach the basic assembly I have done, to give an adea of what I need, but I am happy to email it to whoever can help.

You might have better luck getting assistance over at the AutoDesk discussion groups.  Check out the Inventor forum.  Look for a guy named J.D. Mather.

I didn't get exactly what you mean, but I assumed the flanges are bend after the conical shape is made ( i mean you've made the conical part then you bend or deform it to get the flanges)
in that case as far as i know  INVENTOR can't help you with flat pattern ( Inventor does not do Deformation of that type).
if you need just flat pattern of a conical shape, you must follow these two rules
1- thickness of shape equal to sheet metal thickness setting
2- The shape must not be closed if you are using revolution don't use full revolution instead use angle 359.99, or just cut the shape with a very thin section or gap.

Hello Gardyne and John.
I'm just unable to scan a file to jpeg so if you can try and open the AutoCAD file here enclosed.
And what more than : angle = 180° x D / G to calculate and/or draw the open metal sheet do you need ?
