The Track Model of Test Site

Civic team went to city hall to apply the permit for test site. In order to show the officers what's the track in test site looks like, I created a model in Sketchup. It should be easy to do it. But I did't know what happened the the CAD document in sketchup was not available. I had to draw the CAD by myself. And Auto-cad crashed at least 8 times. I stayed up until 3 am to finish the model of test site.
Finally, I made it!
