Tolerances on one surface are much tighter than those across multiple surfaces. When looking at a single surface, most of the features are created using one machine, a laser or punch. Like machining and 3D , this allows us to hold tighter tolerances. Its when we introduce bends to the geometry that things get a little less clear.
