C3D 2025 Seperate gravity pipe networks pipes automatically placing structure when grip editing

[awardlaw8WBLD]

we recently upgraded to C3D 2025, it has been working great. But recently run into separate gravity networks wanting to combine/add structure when grip edit a pipe.(Ex. we do separate networks for our main/trunk line for sanitary and separate networks for leads.) when doing the leads we draw the pipe from area needing service to the trunk line. It is NOW breaking the trunk and placing a null structure.

We need that trunk to be one long pipe for profiling. 

How do I keep this from happening?? is there a variable to this now? this didn't happen in previous releases

Can you let me know what area I should look at in your drawing?  I see Start and End structures assigned to most of the pipes, I need a good one to test on.

@awardlaw8WBLD This 'feature' was added to Civil 3D 2024.1 and is good for some things (adding a new pipe to an existing manhole, for instance) but definitely not desired for cases as you describe. See THIS thread for a short discussion and a workaround

Thanks everyone for the responses. What I have now implemented in our company standards is a few new layers. Autodesk recommended putting the main Network(trunk line) on a separate layer, and the LEADS network pipe on a different layer. Now you can LOCK the main line layer (C-SSWR-MAIN) and grip edit the separate leads network pipes (C-SSWR-LEAD) and it will not connect with another structure. I am a BIG stickler for layer management in ALL files, it really make a project flow a lot better.
