I am modifying a model that has a thickened surface. After Imake my shape change, I am no longer able to create a thickenedsurface. I get the "Unable to thicken the Surface" error. It showsme a preview, but does not complete the feature. If i do not addthe surface that has the shape change in the knit, then the surfaceis created. Can anyone help please??
