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
You could try creating two separate alignment models in your alignment file each containing separate PGL profiles (name the model as needed to describe each), running your profile named boundaries with those separate models. Once one drawing/sheet is made, reference the other profile saved view generated by its "create drawing" as the secondary view. The alignment can be exported as LandXML then imported into the second model.

I can agree that you may have wanted to create actual PGL alignments to go with your PGL profiles.
Shawn - does your solution mean that ORD doesn't let you filter which profile(s) are shown in sheets? Your solution seems like a long way around, and not entirely intuitive.

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.
There are a few concerns with following a set of client standards and isolating the same feature def and its profile symbology (e.g. existing terrain profile display; making a LT_PGL and RT_PGL version). So it could depend on the client workspace. There could be a solution to modify the element template used to assign a version of the feature def to better isolate. Not sure which way around is longer....
Another reason I want to store my PGL profiles on the centerline alignment is for the annotation of the profile. If I were to store the profile on my offset alignments and then project it to the centerline, I end up with a chorded version of the real profile and it wont annotate vertical curve info (because its now a streched and skewed chorded version of the real profile). This projected profile works great for modeling but not showing the contractor the actual profile info.
