Well I'll be! Sometimes I think I post just to get proved wrong. We generally always always ensure there is an elevation point on both FLs at every crossing, so this wouldn't effect those ones I see. But even so, it's something I should know.
Credit where credit is due! Give kudos or accept as solution whenever you can.
Erm...that's news to me! I thought any featureline will edit the elevation of any other featureline on the same site at any intersection. The controlling one is whichever one you edited most recently.
This was added in a few years ago without much fanfair. I usually don't mention it in my classes or here because I recommend that WHENEVER you have two featurelines cross that you place vertices at those intersection points. It will make life SO much easier then trying to figure out that, "Now, if I edit this, will that change too? I don't remember!" situation.
I personally will never let two featurelines in the same site cross without a vertex on each featureline exactly at the intersection.
I'm with you on that Brian. It also allows you to control the elevation at that point using the Elevation tools vs. relying on interpolation.
If you don't want a kink in the alignment you can use elevation points, but they can be a pain if you don't get it located just right or if the alignment shifts slightly. Then you can end up with 2 elevations so close together that you can't see what is causing a bust. As I have mentioned in other posts, sometimes the Site topology rules cause more problems than they solve.
If we could start over I'd wish they had used a different approach, perhaps something like Bentley has done with their new civil technology where the user applies the rules as needed.
1. If you are not queezy about using gradings; I have adopted using a Relative elevation grading off the face of curb .5 ' at a 1:1 slope and my back of urb is dynamic to the parent FL. Also, you can add trnasistion to get the drop curbs where required.
2. Ever since I found I spend far less time in the elevation editor
3. If they are all in the same site, yes ( avoid crossing FL)
