I'm trying to draw a helical staircase with a bottom plate underneath the steps. Drawing it isn't a problem. I used a sweep with helical curve. Then I converted this part to a sheet metal. But then inventor doesn't want to unfold it. Does anyone know how I have to make a flat pattern from this one with the necessary bending lines?

In real world, this plate as to be deformed , not bended, therefore, inventor doesn't calculate this kind of deformation.
This is a plastic deformation, inventor can't manage this.

Attached is the finished part that I sent to fabrication. It's a major PITA, but they were able to build it.
