Ok, this is being brought up based on a rating on a recent coaster uploaded.
First, let me say, to mark down for use of auto supports is quite possibly the most rediculous thing Ive ever heard of. I only know of one coaster EVER, thats totally wooden, that was done by hand and it took the guy around 3-4 months. Its not without its share of errors, but, it is testament to patience. He though, did that some 2 years ago I believe.
Now, a certain member claimed to have gone into the track and used the "Clear Auto Supports" button, which then deletes all auto supports, revealing any extra supports.
There is one HUGE hitch that debunks this method.
Lets say that I design a wooden coaster, its small, and I want to add lateral bracing, but make up my own type. So, I dont do any wide supports, I just use auto supports to make the basic structure beneath all of the track.
I then go to the corners I want to add auto supports too and I tediously replicate a style and attach it to the existing structure, because you wouldnt just want the timber floating in the air. So Ive made all of my lateral bracing, and of course, connected it too the main structure.
Now say Im the rater, I want to check what he did. I open it up, clear auto supports and bam, all disappears but alot less lateral bracing than was done, and some footers. What happened?
Well, the "Clear Auto Supports" button does NOT recognize beams that were made by hand. As long as its connected to a NODE that as made by the auto supporter, anything connected to it, once that node is gone, is also gone. Theoretically I could do lateral bracing, like that on Colossos at Heide Park (just single beams coming down at an angle straight to the ground) and as long as they are connected to a node that was created with the auto supporter, when you clear those autos, itll delete that beam too, because the node that it was connected to is now gone.
Basically, if you use this method, any leftover supports, you have to multiply by 2 or 3 times. I find an easier method would be to delete all the supports, save as another file. then, create the supports again using the similar structure and wide supports (where needed) and THEN compare.
Just a word to the wise, a bit of caution for rating. I do alot of my own lateral work and so do others. It is frustrating to see people using archaic methods of checking which dont work.
