Hi all  my name's Shaun, I am new to this forum. I am hoping that someone here might be able to help me. I am trying to plot some data and so far had no luck in doing so I have uploaded a .zip archive which contains a excel spreadsheet with all my data. What I am trying to do is map out the the rail system (in Auckland, NZ) for modelling on several rail simulators. Any help is much appreciated

EDIT: It may have something to do with a transition curve? Any ideas?

I don't even understand what you're asking for, so I don't think I could help.

Ok Basically  the zip file attached contains a spreadsheet with track lengths and the radius of the curve. We know how long the curve is & its radius  what i am trying to do is draw them correctly. There is a formula that involves algebra (i think). I was able to calculate the angle but that was useless as the curve doesnt "flow". Here's the wiki http://en.wikipedia.org/wiki/Track_transition_curve If i can get the correct formula to be able to draw atleast one or 2  then i'm sure i'll be able to work it into excel. Side Note: If this is posted in the incorrect forum  where would I go to find the help im looking for?

Not so simple a study, I think. For example: http://www.2dcurves.com/spiral/spirale.html
