In engineering drawings, arcs and circles are dimensioned in views that show the arc or circle. This approach is essential because it provides a clear and accurate representation of the geometric features being referenced. When the arc or circle is visible in the view, the dimensions related to its size, radius, and other characteristics can be directly interpreted by anyone reading the drawing. Proper dimensioning in the view where the shape is displayed enhances understanding and eliminates ambiguity, ensuring that the fabricators or engineers can accurately replicate the intended design.

Choosing a view that does not display the arc or circle would make it difficult to gauge the correct dimensions or understand how it fits within the overall design, leading potentially to errors in manufacturing or assembly. Thus, it is crucial for clarity in engineering communication that dimensions are assigned in the views where the relevant geometric features, like arcs and circles, are clearly visible.
