Say you are putting together a detail that has a dimension in it but for it to look appropriate, things really won't be to scale. What I am getting at, is that you want to put down a dimension that is wrong. Revit won't allow you to override it using the feet and inches symbols from your keyboard. Instead you get this judgmental dialog.
Go back to Dimension Text dialog by clicking on the dimension twice and select the "Replace With Text" option.
- Right click in the text field
- Select "Insert Unicode control character"
- Pick "US Unit Separator (Segment separator)"
Type a new dimension into the Text box and click OK.
In the image below these walls are either 8'-0" apart or 1'-6" apart. You don't know, because of my awesome Revit trickery.
