AHG Help

Owen Jay: You need to figure out the entrance and exit speeds for your ride.

You also have to have a track with an open end, meaning, no closed circuits.


Once you have that, as I said above, you need to figure out the exact speed of where it starts and ends. Then, using http://nldc.interfix.net/calculator (scroll to very bottom) enter in your numbers to get the m/s answer.

Plug those numbers into the AHG and then you wont get an error.


BIG DISCLAIMER! Make sure when you design you take into effect that the AHG will raise or lower the track by +-1m. Thats 3 ft and that can make alot of difference. For Sitdowns it will lower the track, so if your airtime hills are close to being too extreme, youll want to make them 3ft higher to compensate.

Just as if your Inverts are pulling too many g's, the radius needs to be 3ft wider to retain the same g's.

Thanks for the tip Real -- I had that very issue on an invert this weekend that I was messing with.

ok at start of track speed =10kmh/3.6= 2.77ms end speed(not full track haven't finished it yet!) is 57kmh/3.6=15.83ms is this correct if so then I still get the error message! also track is open

Do a screen shot of all your settings -- this might help diagnose.

Are you including the lifthill in the track you are trying to send through the AHG?

Owen, see if a slightly higher speed can fix it. maybe .5 more for start and end speed.

If that doesn't fix it, go higher. If even high speedsettings don't work, the most likely cause is a vertical section of track. AHG can't work with vertical track as there is no real direction to the track then and therefor it can't calculate the bank.

Fornication thank you +Buster took the lift hill out! problem solved

Owen -- Ahhhhh!!! I was always told to make the "element" from the beginning of the free running part of the track all the way to the segment right before it hits the brakes. This would be the first segment after the chain ends through just before the brakes. Sorry I did not catch that when you described what you had in there.

and that still leaves me with my problem, is there something I'm missing in my win32 file folder, or something?

How do you guys heartline the track? Do you make the whole track a segment and then heartline it? Or do you do it peice by piece? I know how to work the H-SAK formula and the AHG, but I can't really put them together. Any help would be appriciated.

You save the entire track from the end of the lift (or launch) to right before the final brakes as an element. It's all just one element. Then you make a new blank track and insert the element. If you used a lift, you need to raise the starting vertex so the element has the space it needs. Save that new track that ONLY HAS THE ELEMENT IN IT, and run that TRACK through the AHG. I hope that's clear enough.

Yah that helps. I just didn't know if you heartlined each element as you inserted it or if you heartlined the whole thing at the end. Do you hearline the whole track after each element is added to make sure the G's are in check

This thing ALWAYS messes up whatever I make, I cant seem to have it work on anything after reading countless threads on it. The color codes are very unclear to me, In whats cases would I use the red and green track. Im always making it solid black.

You use Red if you go from White to Black in the direction the train travels. If you then need to go from black to white, you use green on the segment after black.

It gets rid of bumps and jerks if you choose to let the AHG do the work for you. Which recently, when not doing a wood coaster, I let it do all the work unless I have a spot that has airtime, then you HAVE to make it black.

OH wow, you made me realize that it doesent NEED to be black. I was lead to think that EVERYTHING needs to be a color or it doesent work. Thank you so much Real, im getting the hang of this thing now.
