Is there any setting to make a 2D object? Or at least an object that can only be seen from 2 angles. I tried making an object very skinny, but it did not work.
You can also use curves and keep them as 2D:
Just make it infinity skinny ;)
⇧ ShiftA> Mesh > Plane will add a 2D plane.
Such a 2D object cannot be seen edge on:
