All pipes and structures in network are disconnected

[patrickk17]

My pipe network has become entirely disconnected, the pipes are no longer attached to the structures. The pipes will not reattach to the structure by draging it over a structure. Reviewing the pipe vista all the begining and ending structures are missing. The pipes and structures are still in the drawing with the correct data. However, you can not reattach the pipes to the structures. I can draw new pipes and attach to the existing structures no problem. I can use the attach part command with the structure and pipe, and the pipe snaps to the center of the structure, however, the pipe does not connect to the structure.

The above happen after I audited and purged the drawing.

Anybody know how to fix this?

I don't suppose you've used LandXML to bring your networks into Hydraflow have you? You didn't speciffy Storm or Sewer so I assumed....

If they've been brought into Hydraflow you should be able to LandXML export them back out of Hydraflow and just reimport them back into your drawing as new networks and change them back to your styles as needed. I know this doesn't answer the question of how or why they've become disconnected but something like this might get ya back up and running again.

One question for you. When reconnecting the pipe to the structure do you let the little structure icon pop up first before you snap to it? the only reason I ask is because I had a guy over here simply try to snap it to the midpoint of the structure using simple AutoCAD snaps and he didn't understand why it wasn't connecting the pipes.
