Is there a way to use a featureline or an alignment as a surface boundary?

Solved! Go to Solution.

I still don't have any idea what the problem was but I deleted the featureline, removed all edits from my surface except the items that are not related to this FL and recreated the FL. Then I added the NEW FL as breakline and boundary. This time around, it looks good.
The weird thing is that AFIK, I did the same thing this time around.
Thanks for your time guys! I really do appreciate the assistance.

Hmmmmm. The LOC is picking the elevations from EG. I can see it in the triangles. It is also accepting the LOC as the boundary. because some of it is dead on.
this looks like a rounding thing. I am going to have to go play with it a bit. Be right back.
Good. Glad it is working for you.
As a safety precaution next time and to avoid future messing with the FG. Try this.
Create a surface that contains all your FG work except the tie to LOC.
NOW
Create a new surface call FG FINAL Tie to LOC
paste FG
Add feature line as breakline in here. Then add Boundary.
This sounds like unneeded steps BUT. If tweaking LOC and adding as breakiline and new surface boundary causes issues with leaving artifacts behind at edit time, this creates a break from the FG surface and allows you to recreate the FG FINAL Tie to LOC surface as many times as needed and guarantees no artifacts left to KILL the FG surface that you worked so hard to create.
Just a thought if it is going to get nasty, create a way to protect what came before.
FYI you should be able to use the same Fline for a breakline and a boundary. You should not need a separate pline for this. Not that it's a big deal but it is another object and maybe layer to manage.

I did use the same FL. Thanks. Since I need to keep the PLINE and I don't want to see both the FL AND the pline, I set the FL to a no display style -- AFTER adding it to the surface as both breakline and boundary. But technically, I wouldn't see any harm in using the original pline as the boundary.

One thing I have adopted for site grading is to not add any FL to the surface def, but instead use FL in a grading site with infills. A few control FL + infill works great, so far. Plus I more easily avoid the inevitable complaint because the daylight contour don;t have that nifty curl the LS arch are so fond of.
I like my surface definition list to be very short
Actually, My favorite work flow is to make every eop, curb, sidewalk, retaining wall, et al alignment; use a control plane surface to define the grading scheme, surface profile the line required and voila every FL in the site is dynamic. It take the *Eric Chapel technique to the next level.

joe, I agree on FL to surface. It is too easy to forget that you did it and later wonder why your Final grade is doing that when you want it to do this. Only use when absolutely needed. Generally, never IMO.
And with all due respect I respect your respectfulness. 🙂
Yes this is a good dynamic solution without a projection. I am looking at this through my workflow where the most important thing I need from the LOC is the area in a plan label for SCD. And this is much more important to me than a dynamic LOD.
Question do you close these alignments and can you report the area in plan label without making a duplicate pline object?
Oh there you go giving me the heebie jeebies again. :0
I would bet that I am just stuck in an outdated mindset/workflow/trust issue here. Since the collateral damage is minimal I will be giving this a shot. Heebiew jeebies and all. 🙂
