GDnTExtend

GDnTExtend represents modifiers that extend geometric tolerances beyond their standard scope, such as projected tolerance zones or unequal profile controls. The model captures the modifier symbol, numerical value, and any referenced datum or feature to which the extension applies. Having this data structured separately allows downstream tolerance analysis tools to apply the correct envelope when simulating assembly conditions. It also helps inspection planning software determine when additional gauges or measurement distances are required and documents the notes engineers provided when invoking these advanced modifiers. Use this object to interpret complex GD&T callouts accurately, especially when the drawing specifies requirements that differ from default ISO or ASME rules or when supplier-specific conventions must be honored.
