2027.0.0

Revit 2027 is here, and so is a major update for RevitLookup!

The Revit API has hundreds of static utility methods that were previously hard to find. We've now linked these "Utils" directly to the elements and types they affect. You can now see all related utility data for an object in one place, without having to search for static methods elsewhere.

General

• Revit 2027 support.
• Enabled addin isolation starting from Revit 2027. Finally, Autodesk fixed it.
• Async startup makes Revit to continue loading while RevitLookup initializes in the background.
• Event Monitor is now faster when inspecting incoming events.
• Shortcuts no longer conflict with user settings. The default shortcut is only applied if the user has not configured one.
  There are now two hotkeys to open the Snoop Selection window: F12 and SS. #316.

Postable commands

Postable commands are Revit's built-in UI actions — toolbar buttons, menu items, dialog triggers — that can be invoked programmatically via the PostCommand API.
They're the go-to tool when you need to automate UI behavior that has no direct API equivalent.
RevitLookup now exposes the full list in one place: browse, search, and execute any Postable command directly.

API Coverage

This release covers most of the Revit API Utils methods. Hundreds of new members are now visible directly in the inspector.
