dThanks LBD. I do know how to use sketchup, but fint that in the creative phase drawings work way better for me. If needed I then go to sketchup at a later stage, often mainly if I need to visualize an idea to other people.
And often I have the whole idea in my head and the visual evidence is some scribbles on the back side of an unpayed electricity bill..
What is your creative process in that regard?
