Which view of an orthographic sketch should include the most important details?

The front view of an orthographic sketch is typically the most important because it presents the most characteristic features of the object being depicted. It is often the view that is used to convey the overall shape, size, and layout of the object, making it essential for understanding its structure. The front view helps establish the baseline for the other views by providing a clear and direct representation of what an observer would first notice. Important features, such as doors, windows, and any significant contours or cutouts, are generally most clearly displayed from the front. This perspective facilitates accurate construction and visualization of other dimensions and aspects of the object, serving as the reference point for the top and side views that follow.

Other views, like the top, isometric, and side, while valuable for specific details or dimensions, do not serve the same foundational purpose as the front view. The top view gives a broad overview of the layout, and the isometric view provides a three-dimensional perspective, but they lack the clarity of essential details that the front view conveys. The side view similarly presents additional information but is often secondary to the front view in terms of significance.
