^Well you have to realize that they're designing real coasters, and if you can design perfection with tools more easily, then that's obvious, but with NL, there's just a bit more room for error since we're not designing real coasters.
Also, before computers came out, designers still used tools. They were known as pencil, paper, ruler, and math formulas.
Supporting is a drag. I finally finished the helix and I still have a few turns to do. I'll probably work on the hills next since they're more fun to make. Unfortunately, I can't find any more spots to do complex supports, which were more fun than I thought they would be. Here is another screenshot:
Look at all those headchoppers!
By the way, I'm still deciding what I should do with that one support near the end of the low turn, so it may not stay like that.
