Hi Dana, I am totally clueless: who is "EE"?

even if you stay in the LDT zone, it would be really easy to use EE's HEC
RAS tools in C3D instead of dealing with ArcGIS

you could just landxml your surface and stream CL alignment over, then
copyclip your plines that represent your sections. you wouldn't have to
know much else.

let me know if i can help. I beta tested EE's program and I found it to be
pretty great compared to how I was doing it before. I'd like to hear what
other people have to say.

Re: HEC-RAS Import & Export

hey there... you two...

in the past i have had to end up defining the cross sections as actual
alignments- and manipulate the data as such-

specifically for the angled sections that are a part of the post... not
pretty but accurate... using the vert/alignment editor's report functions to
export the cros section/alignment data is key... and yes it does leave some
cleanup to do...

wading in a sea of imperfection does help us accomodate certain things at
times... 8^)

Not near enough to the Verde River in the Lowlands around our area for the
current set of Projects. The "trial" streams haven't had any hair-pin turns
in them to produce those V-type sections for HEC-RAS to get agita over.

Notice I said "yet" in the primary sentence? ;-)

I've noticed that there are a few "washes" along 260, where this condition
looks like a possibility also.

Time will tell.

Maybe since our topography is more conducive towards "narrow" channels, they
may not be as prevalent. We can then use less of a Left/Right dimension to
define the channel?

Neil I did this recently with the Hydrology>HEC2 Output>HEC2 Multiple and

The only thing I was reminded of is that H-R deals in the "opposite"

upstream.

If I've still got it "incorrect" I'm willing to be wrong - as necessary. ;-)

Can anyone provide sources/advice on how to import and export cross section
and analysis data between LDT/CIVIL Design 2004 and HEC-RAS?

The HEC-2 routines in Civil Design do not allow for bends in the cross
section sample lines. I have been contemplating projecting polylines to the
DTM to create 3D polylines and then using Map to create report queries of
the polylines which could be imported into a spreadsheet and edited to meet
the data input format requirements of HEC-RAS, but this is a lot of work
considering people are doing this regularly. There must be a simpler way.

Hi Jesse,

We have been using that method as well. It is manageable but you can end
with over 100 alignments in your project which is a bit of a pain. The
bottom line is the LDT HEC tool is basically useless because of the way it
was designed. Hopefully the stuff being developed for C3D will bridge the
gap. For now it looks like we are stuck with a tedious job to get there no
matter what we do.

Thanks for the suggestion.

How did you handle "bent" cross sections Don?

Neil I did this recently with the Hydrology>HEC2 Output>HEC2 Multiple and
got what I needed in HEC-RAS.

The only thing I was reminded of is that H-R deals in the "opposite"
direction for Flow than I'm used to thinking about it - downstream to
upstream.

If I've still got it "incorrect" I'm willing to be wrong - as necessary. ;-)

Can anyone provide sources/advice on how to import and export cross section
and analysis data between LDT/CIVIL Design 2004 and HEC-RAS?

The HEC-2 routines in Civil Design do not allow for bends in the cross
section sample lines. I have been contemplating projecting polylines to the
DTM to create 3D polylines and then using Map to create report queries of
the polylines which could be imported into a spreadsheet and edited to meet
the data input format requirements of HEC-RAS, but this is a lot of work
considering people are doing this regularly. There must be a simpler way.

Hi Jesse,

We have been using that method as well. It is manageable but you can end
with over 100 alignments in your project which is a bit of a pain. The
bottom line is the LDT HEC tool is basically useless because of the way it
was designed. Hopefully the stuff being developed for C3D will bridge the
gap. For now it looks like we are stuck with a tedious job to get there no
matter what we do.

Thanks for the suggestion.

hey there... you two...

in the past i have had to end up defining the cross sections as actual
alignments- and manipulate the data as such-

specifically for the angled sections that are a part of the post... not
pretty but accurate... using the vert/alignment editor's report functions to
export the cros section/alignment data is key... and yes it does leave some
cleanup to do...

wading in a sea of imperfection does help us accomodate certain things at
times... 8^)

I'll wait and see what else comes along in the way of replies. Ultimately we
may end up having to use ArcGIS to be the "middle man" between CAD and
HEC-RAS.

I didn't yet have any of those Neil, but I know that they await. ;-)

Not near enough to the Verde River in the Lowlands around our area for the
current set of Projects. The "trial" streams haven't had any hair-pin turns
in them to produce those V-type sections for HEC-RAS to get agita over.

Notice I said "yet" in the primary sentence? ;-)

I've noticed that there are a few "washes" along 260, where this condition
looks like a possibility also.

Time will tell.

Maybe since our topography is more conducive towards "narrow" channels, they
may not be as prevalent. We can then use less of a Left/Right dimension to
define the channel?
