In Revit 2026.4 when panning to connect the wire to another node the wire disappears.
This is a known issue. I recommend putting stuff into a code block and then dragging the code block around instead.
FYI @emrullah.yildiz @achintya_bhat would love to somehow have this resolved in a hotfix.
@EzDoesIt This was a miss, we didn’t catch the bug.
Its fixed for future Dynamo versions. As Jacob mentioned, we will try our best to get a hotfix for Revit.
thanks
Hi, following up on this one. I’ve been able to narrow it down a bit in case it helps with the hotfix.
The issue reproduces specifically when panning with the middle mouse button while dragging a connector: the active wire gets cancelled as soon as the pan starts.
I confirmed it’s fixed in Dynamo Core 4.2 (Sandbox), but still present in Dynamo Core 3.6.2 as shipped with Revit 2026.4.1. Looking at the release notes, the fix landed in 4.0.0 as PR #16519 (“Fixed an issue where the connection was aborted when panning with the middle mouse wheel”), but doesn’t appear to have been backported to the 3.6.x branch that Revit 2026 uses. The regression itself was likely introduced in 3.6.0 by PR #16285, which added the middle-button pan handlers.
Is there any update on the Revit hotfix mentioned back in November? A cherry-pick of #16519 onto the Revit 2026 branch would do it. Thanks!
.NET 8 support ends in November. Things built on that .NET version (including all Dynamo 3.x builds currently incorporated into Revit and Civil 3D) will need to be updated before then. It is possible that some stability fixes will be pushed at that time.
I don’t have a date.
I can’t confirm there is a fix coming.
But I can confirm changes are afoot and you’ll want to be ready to get into the new builds quickly.
Thanks Jacob, that’s very helpful context. I understand there’s no firm date, but good to know changes are coming with the .NET migration — I’ll keep an eye on the new builds and be ready to move to them quickly. Appreciate you taking the time to explain.
