I was trying to make a radius shaped desk the other day in Solid Modeling, but when I tried to stretch an extruded part it would only stretch the part in a linear direction and not follow the radius.
I asked tech support about this and they asked me to submit a feature request for it, since this does not seem possible right now.
Maybe someone has a work around for this other than manually manipulating it, but it would be nice for the extruded parts to stretch around the construction path to maintain the radius in a drawing.
