Pipe fitting annotation size

[RPOY]

I am trying to alter the pipe fitting annotation size from the standard 3.0 to 2.0. When I altered the default value Revit set it to zero, and will not allow me to enter a number into the value field. Is this a fault in the program? The pipe fittings are smaller than when set to the default 3.0; in fact they are too small. Any experience with this issue? Is there a better way I can control fitting size and for that matter 2D single line pipe visibility settings?

You might try checking Manage tab --> Project Units --> Common --> Length and make sure the rounding hasn't been changed to a level that would round your 3.0 or 2.0 down to zero.

Genius! That fixed it. I had changed the rounding as a lazy way to control duct sizing.
