Data reference workflow question

I created a drawing containing the alignments and design profiles for a road
network. I created data shorcuts to all the alignments. I have a sewer
drawing that contains the sanitary sewer network for the project with data
references to all the road alignments. I want to show the sewers in road
profiles for design purposes. What would be the workflow here?

Dref the sewer network into the road network file. Select the pipe network parts you want to see in the road profile. Right-clcik, choose "Draw parts in profile", hit Enter, and select the appropriate road profile view. Voila.

On a side note: I imported my sanitary sewer network from a Land Desktop
project. All the pipe networks came in on the storm sewer layer and all are
referencing the storm sewer parts list. I did not see any option to select a
default parts list during the import process. How can I get the C3D to
import them as sewer pipes, and is there global a way to change them to
sewer pipes?

But I need to design the sewer in the sewer drawing, not the road drawing.

It sounded like you already had your sewer network ready to go. So... design the sewer network in the sewer file, then dref it into the road file and draw parts in the road profile.

Add the profiles with your alignment DS. then you can create the profile
views in the sewer file for design. DS the pipes to the road plans for
presentation in the road profiles. sounds convoluted doesn't it Well
that's the C3d cross we bare.

I did try creating profiles views from the Dref's to the roads, but the road
design profiles won't come into my profile views in the sewer drawing, even
though I created references to the design profiles. Is this not possible?

I agree it is convoluted. It would be great if we could create data
shortcuts to the profile views or utilize the views in an XREF rather than
create independent views.

Typically the road profiles are designed first so
it makes sense to dref the roads into the sewer and not the other way
around.

I misunderstood what you were trying to do. Sorry. What Joe Bouza says will work fine, as long as your sewer runs parallel (more or less) to the road centerline.
When we design our roads, we create an FG surface to go with it. We dref that surface into the sewer files and use that as our design guideline, not the road profiles themselves. But the method you want to do should work OK.

you sure you selected the design profiles when you created the xml file?
Does the prospector indicate the design file did not emerge?

I didn't use XML. I used the Import from Land Desktop tool for both the
roads and pipes. In my sewer drawing I created references to the road
alignments I then created references to the road design profiles but they
are not available when I create a profile view, nor do they show up in
prospector.

Does this workflow not work?

The more I think about it, the less I like the idea of designing pipe networks from road profiles. One problem is what to do when you hit a street intersection. Your pipe design would have to stop at the end of road profile "A" and begin again over on the profile of road "B". Better is to have an FG surface of the road network and create profile views of your sewer network referencing that surface so that your sewer design profiles would be continous.
My opinion, anyway.

I agree entirely, but I still need to get the
road profiles in my sewer drawing. So far I can't do it.

Maybe I didn't read into your post carefully. Are
you suggesting that I create independent alignments for my sewers and use those
for my design? That makes sense as far as dealing with intersections but it is
messy since it would require numerous additional alignments to manage as well as
some re-work to get all the annotation related to the road alignments. Is this
what everyone has been doing?

This raises another question: when a pipe run
is drawn on a road profile, does the pipe length and slope reflect it's true
length or it's projected length along the road alignment?

 

I haven't worked enough with pipes enough to know
about these issues.

I see now the settings are set in the Pipe Network defaults for the drawing.
Apparently pipes can only come in as sewer or storm, not mixed. Perhaps
there should be a way to set the type of system on a per run basis in the
import settings rather than at the drawing level.

I might post a wish on this.

Not the import from LDT. When you create the data
short cuts for each you make an xml file for the data shortcut. you did create
data shortcuts from objects in the drawing after you imported the LDT data,
right?

Yes, I imported the Land Desktop data into drawings
and then created the shortcuts from the drawings. The XML files are generated
automatically when you create the shortcuts. I am misunderstanding your comment
Joe?

Unless your pipe network follows the exact centerline of its referenced alignment, you will see distortions in the profile view different from what you measure with a scale. The labeling will be accurate, (lengths and slopes) but there will be visual distortion to the extent that the pipe network deviates from parallel to the road centerline. (An example would be a straight pipe run along a curve in the road.) Also problematic is that any crossing pipes shown in profile view reflect the crossing pipe's invert at the elevation it crosses the alignment, NOT the actual pipe network. You may think you have minimum clearance when in fact you do not.
For these reasons (and others) we create alignments for our pipe networks and proflile them based on these alignments. We do not reference the road centerline in any way, so that is not a problem for us. We do not, therefore, need road profiles in our sewer design files.

This is becoming quite a learning experience. Since I had the wrong default
settings when I imported my pipes, I need to delete them all and re-import.
I've tried selecting all the pipes and erasing them, but they remain in the
prospector list. If instead I select them in Prospector and delete them, C3D
crashes. If I first erase them and then follow up by deleting them from
prospector, I crash again. What is the proper way to delete pipes?
