i guess i have to take your word for it....but i'm still going to use them anyway! they look meaningful to me and they react the way i expected them to. except the scale part.
But here is a screenshot showing a curve combplot ( green ) and the combplot of the corresponding ( Z-extruded ) surface ( blue ) : I know why the sign of the blue plot is wrong.
I need to rework all this.
