Dear all,

I want to make a kind of spiral out of sheet metal. Now that works fine with a rectangular cross-section, only as soon as I use a trapezoidal cross-section, then my alignment is not correct. How do I make sure that this alignment is correct?

Besides, I want to be able to change the length, widths, and heights of both the cross-section and the strip so that I do not have to create a new file every time. Does anyone have any idea how I can best do this? Especially since there are different bending angles in the strip.

Thanks in advance!
