Illustrator's 3D effects are underpowered for drawing the wanted plate number 2 easily. With a 3D program one would make it in few minutes and any viewing direction would be as easy.
Drawing it in 2D from scratch (=not importing from 3D) is, of course possible, but the plate should be seen to be sure how it should be drawn.
To see it I made this in a CAD ...
I've no idea what the rightmost drawing is supposed to represent. Sorry. However, it's easy enough to make a wavy plate/surface using 3D Extrude and Bevel. The shape on the left is straight line, with a Zig Zag effect applied, then Expanded to make a shape to use for the 3D extrusion.
It can of course be rotated to any desired angle
