@djd711 said: It's sort of hard to explain. The angle has to be measured in relation to the direction of the track at any given time. I think it's the horizontal axis I need. Could you post the model(version <=2014), or a representative sample of, and diagram an instance of the angle you want measured.

Step 1. Buy Artisan; it will be a real challenge even with it and a virtual nightmare without it. Step 2. Ignore all the finer irregularities. Don't try to model them with geometry, your PC system won't thank you. Model the main lines of the ride then use image maps for the finer textures. Learn all you can about extruding along paths, rails etc and how to model effectively with Artisan (including the use of low-poly proxies) then come back and ask more questions.
