Paraline drawings are pictorial drawings of an object, building or interior that give a three dimensional quality. The two paraline methods we use are Isometric and Planometric.
Isometric drawings have vertical lines but their horizontal lines are on a 30 degree angle. This drawing shows three sides and all dimensions are in proportion.
Planometric drawings have vertical lines but their horizontal line are on a 45 degree angle or 30 one side and 60 degrees the other side(both of these add up to 90 degrees). It is basically a square or rectangle that has been rotated 45 degrees, this is commonly used for an interior plan view of a room.
