I am working on a curved roadway the has a single alignment but has two separate proposed profiles. The first profile is the proposed grade line for the Eastbound lanes and the second profile is for the westbound lanes. These profiles are offset from the centerline.
To create my profiles, I have stored them on the centerline alignment. To know were existing ground is at the offsets, I created projected existing ground profiles that were projected from my PGLs to the centerline. The reason I did this was to store my profiles with the centerline stationing.
I would like to show my two profiles on a double profile sheet (the top profile will be westbound and the bottom profile will be eastbound). No matter what I do, both profiles show up on both views. Is the only way to do this would be by putting the two profiles on different levels and shutting one off on each view? Is there a better way?
Thanks so much for any help,
Dennis W
Yesterday, I actually created my sheets by making a few new levels to put my PGL's on and it worked great. However, our client (the state DOT) will not like me creating new levels outside their dgnlib. With Geopak, I could just create two separate profile drawings with opposing profiles and I was good to go.
I guess another idea would be to just have two alignment files but I'm sure you can imagine what a disaster that could be.
I have performed searches like crazy on this subject and was really surprised nothing much came up. It seems really common to have a divided highway with both sides not following the same profile and all running off a single centerline alignment. Imagine modeling if you do not use a single alignment. You would need to model each side separately because the stationing would not be the same on each side as soon as a curve is introduced.
Glad you figured something out! One of the keys to harnessing ORD as a team is file information federation, not only from a software efficiency perspective, but also sharing work among others (even yourself months later ;D) communicating design intent to others and maintaining as much "intuitiveness" as possible. Breaking those out helps describe your intent, yet hold to standards that may or may not pass a compliancy report.
There's nothing wrong with having two separate corridors for each direction of your design. One corridor can point control to another corridor's template point (while each tied to the same CL stationing.) In fact, you can setup your templates used by the two corridors to utilize two separate PGLs as vertical controls. You do not need to use the profile a corridor is placed on as the template vertical control (it does require an active profile, but a floating template origin can make it possible to use a secondary vertical control.)
