Which view on an engineering drawing indicates how to orient two pieces of an assembly?

The isometric view is particularly effective in conveying the orientation of two pieces of an assembly because it provides a three-dimensional representation of the components being assembled. This perspective allows engineers and mechanics to visualize how the parts fit together in real space, showcasing the relative angles and positions more comprehensively than an orthographic view (like the front, top, or side view).

Isometric drawings maintain proportional dimensions and angles, making it easier for assembly personnel to understand the spatial relationships and assembly sequences. This 3D approach is crucial in identifying how parts connect, their orientation, and how they interact with each other, facilitating a clearer understanding of the assembly process.

In contrast, views such as the front view, top view, and side view typically present two-dimensional representations that may not capture the complexity of the assembly orientation as effectively, making it challenging to visualize how the components fit together in a real-world context.
