Square tolerancing uses square tolerance zones formed as a rectangular box around a coordinate, while GD&T uses circular/cylindrical tolerance zones formed around a point — which results in a tolerance zone that is 57% larger with GD&T. Also, coordinate measurement systems do not clearly define...

A nominal dimension is the feature size of the true profile. It is the exact dimension which we would like to achieve ideally. Feature specifics such as size, orientation, the location from a reference point have a nominal size that machinists target. On a drawing, they are shown within a...
Next to the tolerance box, there are separate boxes for each datum feature that the control refers to. Here, the location will be measured related to datum B and C. Next to the tolerance or a datum feature is an optional encircled letter, the feature modifier. The following possibilities ca...
