Modify tools don't appear.

[Brian Myers]

I have a user that isn't getting the modify tools when it comes to Profile modification or adjusting such items as curtain grids.

I'm aware of all the standard ways of hitting TAB, etc, but selecting the proper item isn't the issue. When the profile edge (of anything) or curtain grid line (unpinned, of course) of curtain walls are selected the tools for modification (add-remove segment, edit profile, etc) simply don't appear on the ribbon.

Revit 2012: What would cause this?

Is the user working on a Windows 8 machine? There is a conflict with MS .NET 4.5 framework and the WPF tool kit used to create the Revit UI. If you were working on Revit 2013 the most recent update corrects the conflict, but there is not an update for Revit 2012. Currently you can't use Revit 2012 with Windows 8 (.NET 4.5 is required for Windows 8) or with a PC upadted to .NET 4.5. If you are not on a Windows 8 PC you can roll back the .NET version installed to correct the issue, or if you stay on Windows 8 you need to update to Revit 2013 Update release 2

Thanks Jeff,

Re-installing .NET was my first "gut" reaction, but since it is at a client site I wanted to verify before sending them the instructions. Will update once the solution is tried.

Update:

It was a Windows 7 computer, but uninstalling .NET 4.5 and installing .NET 4.0 fixed it.

For those that require it, here's the current link to .NET 4.0 directly from Microsoft:
