Within the ISO 14405-1 are options which will be applied to circular features. These will be indicated on the print.
GG - Least Square Algorithm (LSQ) Feature
GG - Least Squares Feature
Points are taken on a diameter. The diameter is based on the average of the points taken.
GC - Minimum Feature
GC - Minimum Feature
A diameter is constructed equal to the diameter of the smallest and the largest diameter. Notice the center of the diameter could be shifted to the nominal center.
GN - Minimum Circumscribed Element
GX - Minimum Circumscribed Element
For an outer diameter this will be the largest ring that will fit within the measure diameter.
GX - Maximum Inscribed Element
GX - Maximum Inscribed Element
For an inner diameter this will be the largest pin that will fit within the measure diameter.
LP - 2 Point Distance
LP - 2 Point Distance
LP allows the programmer to create a 2-point distance on a feature. Parameters must be set to select which 2 points that are to be used.
LP - 2 Point Distance
Similar to measuring with a caliper or 2 point bore gauge.
