The drafting standard where I work doesn't use the phi symbol in diameter dimensions and I'm trying to find out how to remove it from a dimension in AutoCAD LT.
How do you distinguish it from rad dimensions, then? Not that most cases aren't obvious, but there ARE cases where specifying "R" or "Ø" before the dimension is the most obvious way to tell.
Type the command DIMSTYLES and go looking for the prefix used for DIMDIAMETER
Use DIMLIN instead of DIMDIAMETER (poor practice)
Use DIMRAD using a special style that multiplies the dimension value by 2X (very poor practice)
