Since I have a suspicion you're asking because of my comments in my review of your coaster, I thought I'd respond and say not to knock yourself out trying to fill in those gaps[:)]. Very few people actually bother to do this. You probably won't get downrated much (if at all) if you leave them as is. Heck, on my last coaster, Copperhead, I started out with the intention of fixing all the missing supports, but by the time I was halfway through, I said
"screw this" and left the rest as the generator made them. It takes LOTS and LOTS of patience to work with custom wood supports. I didn't mean to come off as elitist or anything or imply that your coaster sucks if you don't finish the supports[:D]. It's just that your coaster crossed over and under itself a lot so there were lots of areas with missing supports, so it was quite noticeable. Just mess with it a little at a time until you get a feel for how it works. Oh, and that was good advice that Bud7 gave; I do the same thing. It helps orient you to what exactly you're looking at. Keep building and keep tryin'.[:p]
