I am new in blender and I watched some tutorials on this issue but I did not find any solution.
I want a little curve on a single side of a plane
A solution with Blender 2.82.
In Object Mode , add a bezier curve then pass on Edit Mode.
You can draw a new curve by clicking on icon Draw.
You can draw on a mesh if you select on Tool tab , the Method of projecting depth : Surface.
