Yea, came up on Craigs List about 10 or so years ago, and I jumped on it. It's a great spot, at least so far, there is pressure, but only enough to keep them moving.
It is/was Googles Sketchup, it allowed you to pull the 3d layer straight out of Google maps. It was free until Trimble bought it out, you can still do that, but after a 30 day trial you have to pay for it, the free version no longer allows the import, but there are ways. It's great because there is a plethora of models available to import in and modify and of course you can make your own from scratch.
That is how I built my stand, modeled it then built it.
