What type of drawing is this?

• Oblique

• Perspective

• Isometric

• Orthographic

These types of drawings are flat, 2-D drawings of each side of a 3-D object.

• Oblique

• Perspective

• Orthographic

• Isometric

This is a 3-D representation of the object and all horizontal lines ares drawn at 30 degree angles to the horizontal. Engineers commonly use this type of drawing.

• Oblique

• Perspective

• Orthographic

• Isometric

This is a 3-D representation of the object looks realistic and all lines converge to an imaginary point.

• Oblique

• Perspective

• Orthographic

• Isometric

The front side of this drawing looks flat and the sides and top of the object are at 45 degree angles to the horizontal lines.

• Oblique

• Perspective

• Orthographic

• Isometric

This refers to the ratio of the object in a drawing to the size of the true object.

• metric ratio

• english ratio

• scale

• golden ratio
