If you need help making turns perfectly round, try this:
http://d1jlserver.dnsalias.net/CCDev2/pub_fileinfo.cfm?fid=736 it includes a 3ds object that's a perfect circle, so you can place it above your turn (in the top view) and move the controll points until the track matches up with the circle.
looks good. btw, did you use the HSAK for that? Also, looking at that screenshot in the editor of that turn, I'd advise using 3 segments for it, that way it's unlikely to have as much pumping.
ok then, question on all your rides you use like a lot of segments and when i try to do that it pumps like crazy is that because you make your ride go through the AHG?
No offence but why dont you run it through AHG? Its free to download, and its better if you learn all the aspects for future rides. Just a thought. BTW AHG is really easy to use, apart from on really odd elements.
when i do ahg, all i thought was speed needed to be calculated. But when i enter a ride and its speed, i always get an error. I know thats it is m/s and that you divide the speed (kph) by 3.6 to get the answer, but i still get errors
You have to make sure that the coaster is NOT a complete circut, has no speed altering devices (lifts, launchs, brakes, etc), and that the heartline is what you want. Also it's better to use higher perscision value, they result in a smoother transition, but make sure you remove ALL pumps, as the AHG will only magnify those (depending on perscision value).
