How common is the explicit use of weights to modify the shapes of NURBS curves and surfaces? For example increasing a weight to increase curvature of part of a curve. My impression is editing weights is common in illustration and graphic arts but not common in other uses of CAD.
The most dommon use of weights with NURBS is to create exact conical curves such as circular arcs, parabolas, etc. I’m asking about a different use of weights with users modifying weights to change the shape of curves and surfaces.
This question is due to curiosity, nothting else.
