Paul Aubin came back on BIM After Dark Live to walk through his favorite Revit 2027 features, and instead of a quick highlight reel we picked a handful and went deep on each one. If you want to know which 2027 updates actually change how you work, and which ones still have rough edges, this one is for you.
What We Covered
Parameters as a Service is not brand new, but plenty of people have missed it. Paul showed how to convert locally stored shared parameters into cloud-hosted ones, and the part that surprised him was how clean it was. He expected a second step to convert each parameter individually, and it just did the whole thing. If you are tired of chasing down a shared parameter text file that went missing years ago, this is worth a look.
Coordination Models were the sleeper of the night. Harlan Brumm pointed Paul to this one, and it clicked once we saw it. You can visually compare two published versions of a model directly inside Revit, with green for new, orange for modified, and red for deleted. Even better, version does not matter. You can link a model saved in 2026 into a project running in 2027. On the construction side, that cross-version workflow is a big deal.
The tag updates are small on paper and huge in practice. You can now grab a leader attachment point and move it, and in the family you can flag labels with exclude from leader outline so the leader always points to the part of the tag you care about. A live chat question from John even surfaced that you can associate that setting to a parameter, which opens up some clever tag swapping.
Hosted walls felt like the missing piece. Walls can now host to other walls, which finally makes separate finish walls behave the way most of us wanted all along. Paul put it best when he said the old way was twenty steps and the new way just works.
We closed on numbering rules and the Autodesk AI Assistant. Paul numbered solar panels using filters and partitioning, then handed off a renaming and sheet renumbering task to the Assistant. His big takeaway, and a good one, is to always tell it to show you what it plans to do before it touches your model. As he reminded everyone, nobody is going to fire the AI. They are going to fire you.
