Why are my Diameter symbols displaying as N's on my drawings?
This is usually caused when one of your Window’s Fonts cannot be found by the system. Using windows explorer, browse to the C:\WINDOWS\Fonts folder. Do you have a file named AIGDT ? If not, you should copy this font from another machine that is not having this issue, and install it on your machine, if you are unsure of how to do this, please get your IT department to assist you.
