Is there a way to extract a simple polyline from a profile in Civil 3d 2010? I simply want to offset the proposed profile to indicate another feature, but can't seem to find a way to create an offset-able polyline out of the proposed profile.
Offset horizontally or vertically? What version are you using?

I want to offset the profile vertically within the profile view. I'm using Civil 3d 2010.
Change it to static, offset as you wish then change the original back to dynamic. (The offset isn't dynamic but creating and sampling another surface would get a dynamic profile)

Why try to turn a Profile into a polyline? A polyline can't represent the curves in a Profile, so if you have any vertical curves, the polyline would have to be tesselated.
Why not just copy the Profile? (Select the Profile, right-click -> Edit Geometry, then use "Copy Profile" in the Profile Geometry tools.) Then raise/lower the copy by the desired amount. This also gives you the benefit of being able to put Labels on your offset Profile.
Not that I don't agree that you should stick with Civil 3D objects as much as possible and I don't know the OPs intentions. But your suggestion runs into the same problem as you would with a Surface. Raising or lowering is not an offset.
Since most design is based on a height above ground of some other reference. Raising or lowering a copy would be appropriate. But in a case where an actual offset is required (can't think of an example myself) then is doesn't work.

I presumed the OP wanted to "offest" by raising or lowering which won't obviously be a true offset but sometimes is adequate for the purpose- perhaps he/she will clarify the intent

I agree. As I said I couldn't think of any reason why you would need a true offset. But the OP may have more imagination than I do of his bosses may be crazier than those I've worked for!

Quick dirty method for creating polylines from profiles.
1) Save the drawing as a new version.
2) Delete the surface that the profile is generated from - the profile becomes an editable entity.
3) explode it into a block, then into lines.
4) JOIN the lines - bingo
jim.poole, yours is the only true answer. Thank you Jim, this worked perfectly.
Several examples of things not answering the OP's question:
Change it to static, offset as you wish then change the original back to dynamic.

Why not just copy the Profile? Then raise/lower the copy by the desired amount.

One more option that may give desired results. Create a feature line from the alignment, project it to the profile view, then raise/lower as is or explode, rejoin and offset.
An easier quicker way. Explode the profile, copy to clip board with base point 0,0 and undo twice to get the profile back. Then paste to 0,0.
I believe there are a few apps in the app store that can speed this up as well. There's a free one called "
Reference Polyline From Profile" seems like what you are after, and Red Light has one for $10.
