So I had an intersection with one through street and one teeing off. I used the intersection object only to mantain the PVI of the second street locked to the main street; no fancy pants modelling going on here. The second street profile started at this PVI. All worked fine & dandy until I wanted to add a little profile on the second street showing the crossfall on the main street.
What would you have done at that point?
Here's what I did:
Unfortunatly, that clearly wasn't the right move either. It snapped and labeld ok, but it unlocked the PVI. I can't work out how to lock it again. When I go to Toolspace>Prospector and right-click on the intersection, and then on "Adjust Side Road Profile" I get this box:
I select Relock, but it doesn't work.

I'm guessing that by adding the new tangent you deleted the dynamic PVI, and replaced it with a normal PVI. The problem now is the software cannot put in a new dynamic PVI because the normal one is already at the same station. Try deleting the PVI that you created so that there is just a tangent through the intersection and then re-lock it again.
I moved the PVI to the left a bit so there is a tangent straight through, and tried again. Still doesn't lock.
