Option not greyed out in RiR Ribbon

Why would Options be disabled in my Revit 2024 install?

This is most likely a plugin conflict.

Here is a quick way to start a new instance of Revit without other Revit Addins.

or try using an addin manager to troubleshoot

Unfortunately, no. I physically removed all addins from the five possible locations except Rhino inside and still no dice.

User Addins:
%appdata%\Autodesk\Revit\Addins
%appdata%\Autodesk\ApplicationPlugins\

Machine Addins (for all users of the machine):
C:\ProgramData\Autodesk\Revit\Addins\

Addins packaged for the Autodesk Exchange store:
C:\ProgramData\Autodesk\ApplicationPlugins\

Autodesk servers and services:
C:\Program Files\Autodesk\Revit 2024\AddIns\

I broke this off into a new topic, it’s not related to the thread you posted in.

Please run SystemInfo in Rhino and post the results.

What exact version of Revit are you running, and what version of Rhino.Inside.Revit?

Thanks
