By default, the GPS characteristic is the local diameter (
16、two point size). Other type of size characteristic can be defined (see ISO 14405-1, e.g. 20 0,08 ).Locating the section plane a distance of 0 mm from the end plane is ambiguous on a real workpiece, due to the possible imperfections of the corner and should be avoided.Indication of location specifica
