Haha, I pretty much did spend that amount of time as I had to get the hang of using SketchUp and plus it was the holidays so I had time to try and perfect it
On the last track people worried about there not being enough run off on some corners so on this track I made sure there was plenty, except for turn eight which was a slight problem. I was thinking of making the straight behind it go over a slight gradient so the run off for turn eight could continue underneath the straight.
Well I will hopefully get the run off issues correct first time round on future tracks... but I'm getting there, just too much this time round
