Question

IlIIS eant by an orthographic projection? What is meant by an orthographic multiview drawing? What is the American standard arrangement of views? Why is the top view directly above the front view and so forth (hint: think of common dimensions and how they are used) How do each of the following surfaces appear in the front, top, and side views of an orthographic multiview drawing: frontal surface, horizontal surface, profile surface, inclined surface, and oblique surface? Which of these surfaces classify as normal surfaces? Why? Non-normal surfaces: Given an inclined or oblique surface in two orthogonal views, be able to construct it in the third view or in a pictorial view

Explanation / Answer

As multiple independent questions are given, The answer for first question is given as follows.

Orthographic projections are the method to represent three dimensional objetcs to two dimentional.The projection lines are orthogonal to projection plane which is parallel projections.

When the principle axis of the body is parallel to the projection plane it is callec as multiview projections.
