I've got a surface that displays contours correctly. When I go to Surface Properties-Analysis tab, I can set an arbitrary number of ranges for contours, directions, elevations, slope arrows, etc, and they display correctly.
I can set an arbitrary number of ranges in the slope range box too, but when I click the Analyze button, Civil 3D 2014 hotfix 1 only displays two slope ranges: 0% to 2979736.0077% and 2979736.0077% to 99999900.0001%. (!)
Can someone show me the way forward?
Thanks.

If you can figure out where that vertical face is, eliminate it.
It's a 5MB drawing with about 40 ret walls. The surface builds with no errors or warnings. How do I search for a vertical face?
Ahh. Retaining walls. There are your faces. Can you move the top of wall feature lines over a few hundredths and see if that helps? Do you want to post the drawing so we can test here?
Thanks, Tim:
I defined the retwalls with about 0.1' 'kick' in the toe of wall most places and at least 0.05 everywhere (AFAICR), but I'll try kicking the toes more...
The drawing is 5454KB -- too large to attach to the ng posts. May I send it to you directly?
Thanks, Dave.
I tried that, but the steeper range doesn't display anywhere in the drawing when I do that - it's all white.
It builds with no errors; Civil 3D usually squawks if breaklines cross points or other breaklines... ?
Hi Dave:
I've tried unchecking ALL the "Add Breakline" and "Swap Edge" operations from the surface definition. This still only yields two ranges, but there's a clue: the ranges are now 0.0% to 541.4877% and from there to 99999900.0001%.
Still badly stumped...
If you can't post the drawing directly to the discussion group, try uploading it to Dropbox or Google Drive (or another similar service) and then share the link here.
I can and would love to take a look at this as well. Retaining walls should not be an issue and I don't think the 9999999% slope is one of the walls unless perhaps you have "Allow crossing breaklines" enabled on the surface and/or perhaps your midordinate is too large for some of the wall faces if they have curves.

O.K. it's fixed. Don't have a clue how, but here's what I did:
1) Uncheck every operation in Surface Properties/Definition list after "Import Point File".
2) Surface Analysis tab/Slopes - (wanted six ranges):
input 44 ranges,got 5
input 88 ranges, got 7
input 66 ranges, got 6.
3) Recheck all operations in groups (I might've just as well rechecked them all at once).
After all the silly input in step #2, the ranges have stayed at 6. Someone, somewhere will have a clue why this worked.
Finally, since it wasn't filling in between chord and arc where the topo boundary is curved, I inscribed 144-sided polygons within each arc, trimmed them at BC's and EC's and substituted the resultant polylines for the arcs.

I think there should be an option in all these analysis panels to simply add another band. This would solve the problem where you only seem to get a single band sometimes and would also allow you to add a band to a setup you've developed which just needs one more band. I'm still not sure why when you say you want 4 bands it only gives you 1 anyway.???
On several occasions i have setup an analysis only to have the design tweaked and the banding no longer covers the full range. Allowing me to insert another band can often solve the coverage problem and the simple addition of a band would avoid having to go the whole procedure again.
Go into edit surface style, analysis tab. click on the slope arrows drop down. Change the "group by" property to quantile. Hit apply and then go back into surface properties and try again.
For anyone wondering THIS IS THE ACTUAL SOLUTION to get your slope ranges. None of the other ones worked (excluding DYNAMO).
