i'm doing a road project. i've got profile grades of existing left and right ditches. in some sections we're redoing the ditches so i've got proposed left and right ditch profiles. what i want to show is where i've got proposed ditch grades, i don't want to show existing ditch grades. the new ditches happen intermittently on the road so i would need to be able to turn off the existing ditches at various places. is this possible without exploding my existing ditch grades? thanks.
If the existing ditch profile is from the surface, you can add hide boundaries to the surface.

that's an interesting idea. would that not also mess with my cross sections? i need to show the existing grade in my sections. for the profiles, it's just too much linework to show existing and proposed. thanks for the idea though.
Create a new surface and paste in your finished ground surface. Add a hide boundary around the entire thing and then add show boundaries around the area you want to see profile for. Create a surface profile for that surface. If you turn Automatic Rebuild on, when you change the finished ground surface, this surface will update too. You can then assign a style to that surface that doesn't display anything (aka No Display) or put it on a layer and freeze it.
so basically there's no way to turn off the profile at selected stations without a lot of workarounds?

Correct. Alignment have the ability to mask between specific stations but currently profiles do not.
Another option is to create multiple profiles with the desired station range for each one. The draw back to this is you can't change the start or end station of a surface profile once it's created (at least not that I'm aware of).
Another possilbe solution is to specify the station range for the ditch surface profile when you create each one. Note - you cannot change the stationing after the profile is created.
Third possible solution - rather than creating a surface profile you can extract the ditch featurelines from the corridor and then project them to your profile view. You'll have to label them manually but they can be dynamic to the corridor if you're still working on the design.
Turning off the profile at selected stations has been on my wish list for years. With a design profile you have even less options.

normally i would just explode the lines and trim it, which is what i'll end up doing here, but the road is 5 miles long and we are still in the early stages of design work so the less i have to recreate and redraw the better. thanks for the help though.
it sounds like a cool product but we have trouble keeping toilet paper in the office. maybe autodesk will by up sincpac.
