Scope

This part of GB/T 38762 establishes the default standard operation set for angular dimensions, and defines a series of specific standard operation sets for the following angular dimension elements: cone (truncated such as frustum of a cone or untruncated), wedge (truncated or Two opposite straight lines (obtained by the intersection of the plane perpendicular to the intersecting line of the two planes of the wedge/truncated wedge and the intersection of the wedge/truncated wedge, and by the intersection of the plane containing the axis of the cone/truncated wedge and the cone/truncated cone), see Figure 1 and Figure 2. This Part also specifies the specification modifiers and pattern notations for the above angular dimensions. This section contains the following angular dimensions: —— Local angular dimensions: a) Angular dimensions between two lines; b) Partial angular dimensions. ——Global angular size: a) direct global angular size; 1) least square angular size; 2) minimum area angular size.
