Isometric Drawing
An isometric drawing is a drawing in which the horizontal lines of the object are drawn at 30° angles to the horizontal. This gives us the appearance of 3 dimensions.

For edges that exist but cannot be seen, we draw dashed lines. These dashed lines are called hidden lines.

Orthographic Projections
Orthographic projections are views of an object in a direction perpendicular to the plane of the object.

Orthographic Views
There are 6 basic orthographic projection views:
front, back, top, bottom, right and left side views
