Hi. Thank-you for that. I should have said in Colour. Rhino does beautiful Grey Scale renders but I haven’t see colour ones in the same way as in SketchUp. My point being that the application of materials in SU quickly shows what each surface is. Applying a Benjamin Moore Colour to a wall instantly gives you a feeling about the room without ‘Rendering’ So I use the term ‘Instant Basic Rendering’ that is all that I meant.
