Orthographic projection both 1st and 3rd angle projection

First-angle projection is a method where the object is placed in the first quadrant. The views are projected onto the planes as if the object were between the observer and the projection plane. In this system:

• The front view is at the bottom.
• The top view is above the front view.
• The right-side view is to the left of the front view.
• The left-side view is to the right of the front view.

Third-angle projection is a method where the object is placed in the third quadrant. The projection planes are between the object and the observer. In this system:

• The front view is at the top.
• The top view is below the front view.
• The right-side view is to the right of the front view.
• The left-side view is to the left of the front view.
