Call for Cul-de-sac Examples

In Civil 3D, we would like to expand our solution base for Cul-De-Sac
creation, as well as improve useability. We hope to get are some particular
common (and not-so-common) configurations for Cul-de-sacs, in regards to the
horizontal alignment, offsets and, additionally, 3D design details to help
automate the process.

Preferred examples would be contained in DWF or DWG files. Also, any
available agency standards and examples would be useful as well. We seek
this input to continue improving Autodesk Civil 3D.

If you can help, please respond/send examples directly to me at the
following email address:

mike.rogerson - Add "autodesk.com" at the end of that. If you reply
directly to me from this post, make sure to remove the SPAM protection from
my reply address.

Thanks for any help!

Mike,

Below is a link to the Riverside County web site that contains Standard geometric drawings.

I can give you vertical info if you want.

Hi Gene,

How are you? Thanks for the link - I do have some questions about the
vertical design. In both cases on their guide, the CL ends abruptly at the
center of the cul-de-sac. Now I'm assuming that for the vertical design, a
profile of the curb around the loop is provided? If so, is it plotted in
relation to the CL?

The other thought - does the CL sometimes get extended past the endpoint
that is shown, and that is how the curb elevations are shown in relation to
the CL?

Or... Is some other method used? Feel free to reply directly to me, or to
group, perhaps this will spur some more discussion.

Thanks,
Mike

In our plans, cul-de-sac grading is typically down by showing spot shots. We
profile based on center line, stopping at the curb return. Grading is done
by hand (sloped 3Dpolys), and shown by points. The station-offset paradigm
doesn't work well in cul-de-sacs, so it's not used.

Ditto here. We do a lot of residential cul-de-sacs that are warped in every
possible way. They are all done by hand and shown with spot shots because
the high or low points could be anywhere on the curves.

Good stuff.

It seems there are so many ways to approach the grading of a cul-de-sac.
I've seen situations where the CL actually wraps around the end loop, so
elevations and offsets can be forced from the CL profile but as you probably
have experienced, there is always some sort of "manual" grade determination
in areas.

In the situation of the CL ending at the center, it seems that it may be
much more free-form, as you mention, John "warped in every possible way". I
assume you've typically worked radially from the CL end - grading out to the
curb limits with some min/max grade criteria to determine your points?

Have you ever created an alignment./profile around the curb and set points
that way?

thanks!
Mike

I wish our regulators would allow spot elevations for flowline design. We
have to show gutter flowline profiles with their own stationing to show true
gutter slopes every where.

It would be nice if in Civil 3D they could finally figure out how to show
FGCL and two transition profiles (gutter flowline) with the transitions'
actual lengths and longitudinal slopes in the same Profile View. For
example, the Profile View would have to be as long as the longest
transition profile.

Fred, do you have any drawing (plan/profile) examples you could send me?
Do you mean drawing the transition lines at the true length, or annotating
them?

On each plan and profile sheet we have to show three profiles: FGCL, left
gutter flowline and right gutter flowline. Each has their own stationing
because the flowlines are longer and\or shorter than FGCL due to curves and
transitions.

It would be huge if you could get the three into one Profile View. With the
Profile Data Band sets in Civil 3D you could have a data band for each
profile. Each of the three profiles need to be fully annotated (i.e, grades,
vertical curves, PVI's, etc.)

The regulators want to make sure the gutter flowlines are working for
drainage puposes. They want to make sure they're not getting too flat around
curves and through transitions.

This would be just huge.

Fred - Sheesh, you guys want everything. :smileyhappy: Kidding.

Actually, we've had that on our radar for some time. Maybe I need a kick in
the head or something, but there were some details about the stationing from
offset to offset to CL that I'm a little fuzzy on. I'm sending you a direct
email to get some more details.

Thanks!
Mike
