Dear SolidWorks Experts,

I would like to model such bent sheet in SolidWorks.

The red colored bend angles on all four sides, are supposed to be parametric (they can be changed).
Magenta lines are just there to visually show that both first and second Flange, have the same distance from the Fixed face:


How do I model such Sheet Metal in SolidWorks?

I can't use Edge Flange individually on each of the 4 sides, as it creates an overlapping flanges:

I can't use Miter Flange, because it will create the same "blue" bending angle on all 4 sides.

I also tried to create Loft. And then convert it to Sheet Metal. But this approach fails as well, as SolidWorks raises 'face for this edge is not planar' message:

I attached the Part file from the last screenshot.
I would be very grateful for any kind of help.
