I am encountering issues with the "edit boundary" tab on the ribbon, as well as "finish sketch" when the edit boundary tab DOES show up. i don't know how to finish the sketch without this, so i have to undo everything. i have seen other posts related to this issue, but none of the solutions resolved anything for me. does anyone have a suggestion or solution on how to fix this?
We have also run into this, and I have found a few workarounds.
1. Try hitting the black Save button -- this will sometimes return the ribbon back to normal.
2. Check the version of .NET your computer is running--if you are using Revit 2012 and have a version of .NET higher than 4.0, it will cause ribbon problems.
3. Use a keyboard shortcut such as FS (Finish Sketch), FG (Finish Group), etc.
4. Try unchecking all the boxes in View>User Interface, then re-check them.
If you are using Revit 2013, be sure to install Update 2, as it has apparently fixed the ribbon problem.
