AutoCAD Civil 3D

Is there a way to place a node within a pipe length without splitting the pipe in two? Our application for this would be catch basin leads wherein connecting to the mainline would not always require a manhole.

Any comments would be greatly appreciated.

I don't think this is currently possible. We have needed this functionality ourselves and are not aware of any ways to do this without creating multiple pipe segments. If anyone knows othwerwise please share.

Civil 3D will want to split the pipe to put a 'null' structure to connect another pipe. However, on a labelling basis, you can use a 'Spanning Pipe' label to make the split pipe appear as a whole pipe.

Or, you can add the crossing pipe in on a different pipe network, making it appear to connect to the original pipe, but C3D doesn't actually make the connection. I did this with pipes we were connecting to a box culvert. In profile and plan, the pipes appeared to connect, but in different pipe networks, C3D didn't actually make the connection, so it didn't split my culvert.

I knew somebody would come up with a workable solution. Thanks for the suggestions. Seems some aspects of C3D require more workarounds than others, especially pipe networks.

Good workaround but when your main is edited, you'll have to manually edit the leads' alignments and inverts. It's what we have though.

Pardon  my ignorance but wouldn't it have to be 3 pipes in the field attached to t tee fitting? Like in the the HDPE catalogs hmm. per haps ADS has a c3d catalog? 

I'm thinking null structure

We've had instances where we were tying a new 24" RCP pipe to an existing 96" RCP. Our detail showed them cutting a 30" hole on the upper half of the 108" to connect the 24" and grout in place. No structure. Also, similar connection to an 8' x 8' box culvert. Cut a hole above the perennial flow line and grout the pipe into it.
