Category in Advanced options dialog box: Dimensioning - general
Set this advanced option to 16 or 32 to set the precision of the knock-off dimensions to 1/16 or 1/32. Otherwise the precision is the one that is set in the dimensioning dialog box. The default value is zero. Other values are ignored, and the knock-off dimension precision is the same as that for other dimensions.
Knock-off dimensions are used in integrated dimensioning.
