Think of SketchUp as literally a digital sketching tool. As an architect, I use it almost daily as a quick way to get digital "sketches" for clients. I just used it for the first time to help with a table design I want to build. So, for reference, the basic images here took me roughly 2 hours to create. That included the drawing and figuring time (I changed things on the fly as I noticed trouble spots while building it digitally).
Architect professionally, golfer wannabe, theologian by grace, woodworker by... well... nothing yet.
