I am looking for someone better than I am at "drawing" up a few designs ideas I have for a new filter I would like to get built, so I can send them to my builder. 3D pics would be awesome, but 2D works just fine. Or if anyone can point me to an easy program to draw them up myself that would be good to. I can scribble an idea on paper but would like to pass the builder some nicer plans to go by. thanks
