I tried snap to mesh and subD options that work pretty well to create subDs over an object for retopology.
But once you end up creating faces you cannot use the gumball preserving the snap to that objects.
I wonder if this is something possible or in the wish list of others too.
what are you snapping to? a mesh or a nurbs object?
my first wish would be to snap to a mesh, for retopology adjustments.
But, the chance to snap to other types of geometry would be great too.
