When dimensioning in your model, if you need to have a dimension that is empty (without the dimension value), whilst keeping the dimension line work and ticks. There is a simple way of allowing this in Revit.
This process is especially useful if you are dimensioning structural elements that the Structural Engineer is setting out.
If you double-click the dimension value.
This will open the Dimension Text Dialog box.
If you use the Replace with Text option, (Revit won't allow you to enter a space as the text value), but if you right-click in the area to the right of Replace with Text option, you will get a menu flyout.
Choose the ‘Insert Unicode control character’, and then select the ‘Unit Separator (Segment separator) character.
The result will be a blank dimension value.
