GDnTZone

GDnTZone defines the tolerance zone geometry associated with a GD&T control. It specifies whether the zone is cylindrical, planar, or another shape, and includes the size, orientation, and modifiers that govern how measured features must lie within it. By modeling the zone explicitly, the API allows quality software to simulate inspections, verify gauge selection, and visualize the allowable variation. The object connects back to the controlling feature frame and any projection requirements to ensure context is preserved. Use it when you need more than just a tolerance value—you need to understand the spatial region that embodies the designer’s allowable deviation.
