WebThe GD&T Flatness symbol references how flat a surface is. It is not dependent on any other datums or features. Flatness is a form control, because it is used to control the form or shape of a feature. It controls how much a surface on a part may deviate from an ideal plane. The Tolerance Zone for a Flatness Tolerance is based on two parallel ... WebCreating and Applying GD&T Inspection to a Project in GOM Software. The easiest way to apply GD&T to projects is with the GD&T quick creation menu. Start by creating some simple form GD&T call outs that don't require a datum system, such as roundness and flatness. The remaining form inspections would also have a similar creation sequence.
