Does anyone know if there is a product or addon that can work with solidworks to render a 3d model in the same general way that an industrial designer does a pencil sketch showing edges extended and feathered out, etc.  The reason I want this is customers often consider the rough 3d models I present to them as the gospel final form.  By rendering them in a mode which suggests an industrial designers sketch it becomes much more obvious to the customer that the presented models are ideas to consider.
