What does an angular dimension specify in a design?

An angular dimension provides critical information regarding the angle between two elements within a design. By specifying the angle, this dimension helps engineers understand the orientation and alignment of features, which is crucial for ensuring that components fit together as intended. Additionally, angular dimensions often include the location of the angle in reference to other elements, allowing for precise placement within the larger assembly or system. This is essential in designs where specific angles can affect functionality, aesthetics, and overall performance. Hence, understanding angular dimensions is vital for any engineer working with parts that require precise angular relationships.
