Hello!

Maybe this is an easy one but I´ve pretty new to sheet metal. I´m going to make a metal plate which is supposed to be completely roll bended, and I want to be able to flatten the part. How would you do?

In this case there is off course three parameters, the radius, length of arc and the angle.
I wonder, is there a way to make a sheet metal part and only defining two of the parameters and let the third be the resulting parameter, automatically?
(Length of arc for example) Now I have to calculate the third, when trying different dimensions on the other ones.  

Or could I do it the other way, making the part as a profile which I extrude and then make it into a sheet metal part afterwords?

Attaching an example below. (Made with the Scetched Bend-feature)

With kind regards

Josef
