I know there was more than one thing wrong when I was on this thread trailing zeros in angular dimensions
When I use a diameter or radius dimension I get a trailing zero, in SW2016 SP5.
There is no setting I can find, I just get the zeros up to the precision set. the radial/diameter dimensions don't follow the standard set globally for dimensions (which I set to smart trailing zeros).
I guess this is also cured in SW2018?
