The other day I was looking at a sheet a user reported it was impossible to select a floor plan view on. It seemed as though Revit did not see the view port on the sheet. People frequently pin views to make it a bit harder for other people to move them on a sheet accidentally. That will still allow a view port to be seen by Revit, it will still highlight as the cursor travels over it.
Then I thought of right-click Hide In View > Element. I used Reveal Elements and I could select the viewport. Using that tool does not hide what is visible in the view, it just disables the ability to select the view port.
Good? Bad? It isn’t expected, well I didn’t expect it.
