How do you most easily do a sheet metal plate that needs to follow a surface?
L1 is less than L2, and a radius of the plate?
Grateful for answers

You can use the Tool "Thickness"; apply in the surface to create the sheet metal solid.
The thickness value you will input in that operation have to be the same value as the "sheet metal rules" Thickness value, if not the part will not flat.
See the help files for how to use the "thicken/offset" button on the model tab.
