Error on import of xml file into Storm Sewer

[Anonymous]

I keep getting an error when I attempt to import the attached xml file into Storm Sewer. I have checked the flow direction and it appears to be correct. Any other issues that would cause an error on import? Any help would be greatly appreciated.

Thanks

Matt may not be up yet.  You do know that
there is an NG for this application "autodesk.civil3d.stormwater"? 
One of the things that seem to spring up is having two pipes flowing from the
same basin (M.H.).

I can't have two pipes flowing from the same structure?

[Matt.Anderson]

Hydraflow will only allow one pipe to flow "OUT" of a structure for LandXML in 2009. Hydraflow traces the flow direction to determine what ending structure is the "OUTLET", so if two structures have OUTS, it can not determine the flow logic on import from LandXML.



In a network such as this, I would do a couple of things.



1. Take the individual set of networks and export them one at a time until I could determine what might be causing the export, rather the Hydraflow import error. This might include erasing sections of pipe to simplify the system, or LandXML in the network in a new drawing, erasing some of the extra parts. Audit after each network part erase.



2. Watch Start End oddities. While flow direction typically fixes the structure error, there are times when items such as Pipe 2-3's Start and Ends are backwards. The key here would be to review Prospector to inspect the Flow Direction column for anonomolies.

I am basing this on what I have gathered in these
Newsgroups.  I am fairly certain that is correct, two can come in but only
one outlet.

Bill -



For LandXML import into Hydraflow, the limit is 4 in, 1 out. Hydraflow by itself does not have a limit however, so if you need 5 inflow pipes, your 5th pipe needs to be drawn in Hydraflow itself.

Matt,

I have checked my flow direction and everything looks ok. Also there is only 1 out of each structure. I do however have multiple "outfall" in this system. Is this the problem I'm running into? I created this network all together. I did not create a network for each seperate system and then import them back into cad via xml file by renaming the xml file. Do i need to go this route?

Thanks Matt:

You have to look REEEL close, two "or more" in
but only one out.

There are none that i know of. I can import a side-by-side, single
network without errors.

Watch how you draw your network - and do not switch between drawing
upstream to downstream because the backwards start-end relationship.
