[ORD] Linear element at intersection of Multiple Terrains?

Question

Hi all, 
 
 I need to get a 3d linestring (to define a retaining wall base) for the location that two terrain surfaces intersect. The only way I can do this quickly in ORD is to use the MicroStation 3D modeling tools. 
 
 My current workflow is to use the Modeling > Mesh > "Create Mesh from Ellements" tool to get a simple Mesh from each surface and then use the Modeling > Surfaces > "Compute Intersections" tool to get a 3d linestring at the points these two meshes intersect. I then use the "Plan by 3D element" tool to get Geometry and Simplify it if I need to. 
 
 Do we have any equivalent workflows using the OpenRoads tools to accomplish this? 
 
 Regards, 
 Mark

I was looking for such tool a while ago and found something interesting within gINT/geotechnical tools. Unfortunately for my configuration tool didn't wokred and I used Microstation Mesh Tools. In my scenario I had a rock surface that sometimes went above the existing terrain model (errors in survey on in triangulation) and I wanted to find these areas. Another option is to create Deltea Terrain Model(Isopache) and display 0.00 contour, and drape it onto the one of the terrains. However to display 0.00 contour as permament graphic I had to export terrain back to DTM and then us the SS2.SS4 tools. 
 
 Please test the tool belo, and drop a line if it worked for you.
