From my experience with SS1 I don't think you can use the generic move command to move Civil Geometry elements. That is one downside to this technology.
After a query to a Bentley development team member it was my understanding that we could move geometry by attaching it to another file as a reference, move the reference and then merge the moved elements into the new file, but it turns out the rules are not carried forward with that workflow (at least not in SS1). You might try it in SS3 and see what happens.
I'm keenly interested in seeing how this task might be done, or if it is even possible.
