Hello,
I have reached the point in my project where I need to tie-in the carriageway (dual carriageway, channels and lane markings, both ends of the alignment, so 20 elements which must be aligned both horizontally and vertically)
I have searched the training and the communities, and haven't been able to find anything that goes through the best way to model these tie-ins to existing, how best to measure the required existing dimensions relative to the geometry.
Can anyone provide any guidance, or point me in the right direction?

How about using Point Controls? To control templates' points' location, you can tie them into linear elements both horizontally and vertically.
Is that how you normally do it? My concern is that it's creating numerous controls that will be changing independently of each other, rather than a controlled pivot from the geometry to the central reserve and so on outwards to the hard strip and verge
There are several ways to do this:
- From corridor tools: point controls via linear elements or Feature Definition, via Point Control with offsets set up;
- Template Constraints: Parametric Constraints or Feature Definition Constraint;
- Superelevation to tie in cross-slopes;
I usually go for linear objects with Civil Rules at the tie-in/transition sections. ORD creates dynamic connections and when these linear objects are changed, the Corridors are updated on the fly.
Sorry, meant to come back to this earlier. What follows is the process I ended up foillowing, no idea if its near to "best practice" but it did what I needed it to do, though it just seems a bit more laborious than my MX process was, especially since getting even simple offset and gradient measurements from ORD is awkward.
