DREFs not updating automatically

[Joe-Bouza]

Why would this start to happen? did a system variable reset?

I've also had issues with that in C3D 2026, but haven't figured out a trigger. It sometimes happens with pressure networks, pipe networks, and alignments.

(command "AECCFORCESYNCHRONIZEREFERENCES") to the acaddoc.lsp

do you think it could be a hinderance?

Wouldn't that just sync on open? Is that what you're noticing?

[Joe-Bouza]

correct.

I don't see anything that command should mess up. But then again, this is C3D we're talking about. The few times it's happened to me I chalked it up to our project being on ACC and Desktop Connector not working properly. But it could be something else going on.

That's funny - I also ran into non updating pipenetworks recently and chalked it up to the project being quite big and Civil3d just being wonky. (I'm in 2025.2.2 though)

But the fact that it's happening to others without a clear cause is something between a nuisance and deeply concering.

This stuff should "just work", otherwise DRef's are sort of pointless.

Updating the acaddoc.lsp is a nice brute-force solution but it might slow down opening times for files with a lot of references.

I also discovered other issues that were not a problem a release ago: for example automatic corridor intervals at elevation targets are suddenly not created although the setting is set to "True". This can potentially lead to very unpleasant situations.

We are in the remarkable situation that we don't get any new features for certain parts of the software yet still fresh and hot bugs are introduced. Autodesk must have discovered vibe-coding...
