Title: Pressure Pipe Network Civil 3D
Post by: mailmaverick on November 17, 2018, 01:38:40 PM

Anyone working here on pressure pipe networks in Civil 3D ?

I have a drawing containing multiple LINES having different Z-coordinate of Start and End Points, representing start and end elevations. Also, each line has pipe diameter data stored in form of Object Tables (GIS Data). All the LINES are connected to each other as a network.

How to convert all LINES to a Pressure Pipe Network ?

Maybe like this?
export to .shp file using "mapexport"
then import as pipe network using "aeccimportgisdata"

Thanks for your reply. I did this. But civil3D imports pipes as gravity network, not pressure pipe network. Don't know why.

If you join all the lines to polylines, how many wold you end up with?

If it is not to many polylines, I would create 3D polylines from the lines (use data extraction to get the coordinates into excel and script the 3D polylines into C3D), and create the pressure network of each 3D polyline.

Might try to 'cheat'

Export your lines with object data as shp file

use method above to import the shp file and create "gravity" network using a centerline only pipe style

this should preserve your vertice elevations


EXPLODE *shudder* the pipe network

then use _CreatePressureNetworkfromObj
to then create the pressure network....

Or just create the network from objects to start with?

Can you post the DWG or a part of it?

Still Guessing

Create and Industry model from objects
