OpenRoads Terrain Import / Update Keyin Help

Hi all,

We have an OpenRoads model that includes some linear templates and surface templates built from MX strings and triangulations. The intention is for us to update our MX string model and MX triangulation(s) and re-import the strings and update the OR terrain linked tria into OpenRoads (which updates any OR linear or surface templates accordingly.

Using info in the "Supplemental Information for MX users" in the SS4 OpenRoads help, we have added a script into our input file (SCRIPT, GEOMETRY FILE IMPORT file=MX model=openroads) that successfully runs a keyin to re-import (update) the MX strings into OR that dynamically updates the OR design.

We are trying to implement the same methodology for terrains, but the example keyins "terrainmodel import file=model.fil model=DESIGN edgemethod=NoRemove" or "terrainmodel updatefromsource"  do not do anything and it seems odd that the examples do no specify a triangulation name - only the model.

Does anyone have any experience in the terrainmodel import or updatefromsource that can help?
