I have a planar bezier curve, this curve is in general not closed but it can intersect itself.
What I want is to give this curve a finite width in the plane of the curve. I have found many ideas about giving a curve volume or extruding out of the plane of the curve but that's not what I need.
Is there a way to achieve a finite in-plane width (as if I was drawing the curve with a thick pencil) ?
Thanks!
