RevitLookup 2026 2026.1.4

On-demand member evaluation
Earlier versions evaluated every member as soon as you opened the RevitLookup window.
That was risky, because RevitLookup would call terminal methods and methods that modify the object without asking, and for large objects you had to wait while hundreds of slow calls ran.
Methods that return void could not be executed at all.
You could see them in the list, but RevitLookup had no way to run them, so you could never invoke one or confirm it worked.
Evaluation now happens on demand #298.
When an object opens, RevitLookup evaluates only the members it considers safe to call, now it's members from System and Autodesk.Revit namespaces.
Everything else is deferred until you ask to evaluate. Opening even heavy objects stays fast, and you decide which expensive or model-changing members actually run #239.
Methods that return void are now runnable too, handled as deferred members like everything else, so you can finally invoke View.Print or similar methods.
To evaluate a deferred member, two new commands were added to the row context menu:
- Evaluate (F8) runs the member.

- Evaluate with transaction (Alt + F8) runs the member inside a Revit transaction, which some members require in order to execute. Any changes the member makes are committed to the document.

If you hit a member that should be evaluated automatically, or one that should not, please report it in the Discussions for this release.
