Parallel Projection and Perspective Drawings

Axonometric sketching is used to visualize 3D volumes by projecting vertically from a plan. When the plan is rotated (skewed) so it sits at 30° or 45° to the horizontal, an object could project up from this and add true heights of the elevation to produce pictorial drawings of spaces or objects.(Isometric is a type of parallel (axonometric) projection where the X and Z axes are inclined to the horizontal plane at the angle of 30⁰.)

Cabinet Oblique Drawing-A diagonal drawing where half of the actual size of the side of the object is taken. In cabinet diagonal drawings, they are shortened by half of their true length to compensate for distortions and so that the human eye can study well.

Objective

Explain difference between Isometric, side views, exploded views, Axonometric, cabinet oblique, and 2-point perspectives, worm views, and bird views with the same design of the building.
