HI,
It seems that it is still hard to change fonts of certain elements within Revit.
The element that i encountered was the "Pipe Connector". It has a label "Diameter" in bold blue that gets in the way of everything, to the point that i had to delete all the connectors while i am making adjustments to the element i am working on, then recreate them again at the end....
Little annoyance, i know.... but it save a bunch of design time, and makes Revit more user friendly.
thanks
