Is there a tool that can export or extract a 3D feature from a terrain element, linear template or corridor such that the result is no longer tied to the originating corridor, linar template or terrain element?
Take a look at the 'Plan by 3D Element' command which will take a 3D graphical element and split it into a new 2D element with an associated Profile. This will create a new element without any rules back to the original element or source.

Sorry to have taken so long to post this follow-up, but this it closely related.
But what if the Terrain Element is in a Reference File?
We have a huge DTM and DGN with the terrain element. It takes forever to open any InRoads dialog box with lists of features. I need to make a Civil object from two Breaklines in the DTM.. I can see they exist in the Terrain Element by turning on Source Breaklines using Display Overrides, but trying to select these two breaklines using native InRoads left my PC acting like it was working, but after getting a new cup up coffee and even making a fresh pot, the situation was unchanged, leaving me no choice but to kill the session.
There really needs to be a way to extract things like this even if they are coming from a reference file. And there should be a way to demote any Open Roads Elements to dumb graphics without having to jump through a lot of hoops.

Five years later, do you have a solution for this? One example problem I have is a proposed curb line in a radius that drifts inside and outside the existing curb. The terrain alternates between showing the existing pavement and the existing top of curb in the new curb profile. In Inroads I would have just displayed the existing gutter feature in that profile as a guide. In ORD, I have not found a way to do this without tracing over the existing gutter feature in plan view and setting the existing terrain to the active profile in order to project it. I've tried to project the terrain features but they just laugh at me!
