Meeting Proposed Terrain with Existing Terrain at Proposed Boundary

Question

Hoping this question is a fairly straightforward one but I haven't found a solution online. I'm trying to make my proposed terrain match the existing terrain at the boundary of the proposed work. What's the best way to accomplish this? 
 Thank you!

I believe this is the problem. We need to create a feature from this boundary, but I am not sure that 3D elements in the 3D model can be features. 
 Can you go to the 2D model and create a horizontal feature? I believe the best way might be to use the "Single Offset Entire Element" tool, using an offset of 0. Once you have that horizontal feature in your 2D model, you should be able to assign a profile from your existing surface. After you have done that, I believe you can add it to your terrain. 
 There may be other ways to accomplish this. There could also be other steps you need to take to adjust your modeling to best represent what you really need.

I assume that using contours means you created several independent features, each with their own profile. If true, you can simply add the boundary to the proposed terrain. If the profile of the boundary is set to the existing terrain both will use the exact same elevation.

Kevin, 
 You mention the boundary is part of he proposed terrain. Does the boundary have a profile? If not, this is where you set it to follow the existing terrain. 
 To set the profile of the boundary to the elevations of the existing terrain: 
 
 Set the existing terrain as the active terrain. 
 Open the profile model of the boundary. 
 Set the profile of the active terrain as the active profile of the boundary.

You can use the Profile from Surface tool from your plan view without opening the profile view. 
 I'm not certain how the profile view would handle a closed element, so that could be the issue with that.
