@Richard3D thank you.
I am using Revit2023 at the moment.
So yeah, I have tried Revit Connector once which I download with Workstation Launcher. And that failed as I wrote here since there’s a problem when export to Omniverse.
I deleted that Omniverse plugin, and now I tried to install through NGC Catalog, as suggested here .
After running install.bat I got RevitOmniPlugin.addin file.
However, when starting Revit, I got this error.
Any suggestion will be appreciated.
