Answer :
Final answer:
False, an orthographic drawing includes more than just the front and rear elevations; it typically shows multiple views, such as the front, top, and sides, to fully convey the three-dimensional shape of the object in two dimensions.
Explanation:
An orthographic drawing is a method of representing a three-dimensional object in two dimensions. It consists of a series of flat views of the object, where each view shows the object from a different angle. Typically, an orthographic projection includes the front, top, and side views, and these are arranged in a way that represents the object in a clear and precise manner. To say that an orthographic drawing shows the front and rear elevations exclusively is false. In fact, it includes more than the elevations; it should also show the plans and the sides of the object, providing a comprehensive understanding of the object's shape and structure. Elevations exclusively are not enough to fully define the shape and dimensions of an object, which is why orthographic drawings include additional views. The use of orthogonals and various perspectives, such as linear and atmospheric, can enhance the representation of depth in a drawing, although these are more common in artistic works rather than technical orthographic projections.
