Hello
This may be really simple but I have three chains in my project. One is the road centerline chain and the other two are edge of pavement chains. I built my existing ground cross sections using the road centerline chain and am using the other edge of pavement chains to make the existing roadway and build extra lanes from. So really I’m wanting my edge of pavement chain stations to correspond to the centerline station. Any help in doing this is greatly appreciated.
Hey Brandon: As has been described already it is not possible to make the stations always match all the time unless the centerline is perfectly straight. What has not been shared is any sort of potential solution.
There is not a perfect solution for your situation but there you can improve the correlation of stationing along the edges of pavement by use of equations. By adding an equation to the stationing of the edge of pavement at the end of every curve, you can synchronize stationing in the tangents. Thru the curved portions there will still be a discrepancy in stationing. The command you want is Add Equation.
Honestly, adding multiple equations is a bit of a pain and the benefits are limited. I would not be inclined to do this for my projects, I don't think but it is a potential partial solution for you. FWIW, this sort of use for equations in common practice in various jurisdictions where divided highways have two baselines, one on each inside edge of pavement..
