Gap in my 3D Model

Question

I'm working on a rail design in OpenRoads Designer, and there is a gap in my 3D model. I have created a ditch alignment and profile. A ditch point is point controlled to the ditch profile to aid in ditch sloping. A part of the issue is that the end condition of the ditch can't solve because it appears the terrain model does not extend far out enough (i.e. there isn't solid survey in the area. Any suggestions on how to resolve. I have included plan, x-section, and 3-D model views.

Try an End Condition Exception. That should allow you to modify the EC without impacting the drops. Once supplemental surface is added, the Exception can be cleanly removed. The other possibility is to place two components to your EC area with a display rule that toggles between the two when ground is not found and uses a non-EC version instead.
