Using Civil 3D 2012 SP 1 on Win7 Pro 64-bit.
Is there any reason why a corridor model would not be respecting the manually entered superelevation values in the alignment? I have several stations that should be calculated with even superelevation values, but they aren't. For example, at station 0+080 on my alignment the left crown should be running at -3%, but it is actually being calculated at -2.47%. It isn't just one station; it's most of them. No overridden stations, vertical targets, etc in the corridor. Just a fairly straight-forward align (hor/vert) with super, simple assembly (two lanes, shoulder, daylight), simple corridor.
Solved! Go to Solution.
I haven't had any problem with manually entered data. We create alignment/profile in one dwg, then dref that into our corridor dwg. You might check that the correct lane is being applied from your assembly to your super. It makes a difference.
Sorry, I've been away from the project for a week.
Everything is contained within the one drawing. I added the super manually using the tabular editor. The road has varying crowns and not "proper" superelevation. It's a mill and overlay, and we must match what's there (steep fill slopes).
See the attached image showing the tabular editor. I've gone as far as entering the crown for every station. I've attached a pdf of the slope stake report as well.
You'll notice the following stations are reporting differently than what I entered:
While it's not off much, it's off, and I'd like to know why.
Subassembly crown by default is -3.00%.
I can't for the life of me figure out what's going on. I'll have to punch the data into a spreadsheet for now. Contractor wants the layout this week.
Thanks for any insight!
I'm sure you have, but I'll ask. Did you rebuild the corridor before running the report? We can make changes to the superelevation and it does NOT prompt for a rebuild.
The data looks correct. I'm with Lisa, I think we need to see the drawing at this point to see what's going on.

Ah, a good challenge, but I think I found it
It appears when the superelvation wizard was used the "curve smoothing" was on and set for 50m. When I plotted the superelevation you can see where it deviates from the design grades, thus giving you weird grades. RT-Click on the table column headings and turn on the "Curve Smoothing" column. You can set them back to "0". That should take care of it.
See the image.
Thank you Bruce. That was exactly it. I had the "curve smoothing" column hidden. For some reason, it defaults to 50m, but the problem is fixed now. I don't recall running the wizard though . Thanks again!
