Orthographic drawings are different from other types of drawings because:

• they show multiple views of an object from different angles.

• they use only one perspective to represent an object.

• it makes the object heavier.

• it changes the object's color.

• Views are aligned

• Use of lines: solid (object), dashed (hidden), center lines

• Use of color pencils

• Drawings must be on plain paper

The six possible 2d projections of a 3d object are called this
