Pictorial drawing in this volume incudes parallel projection and perspective projection concepts.
In Parallel projection:
* The concepts of axonometric projection i.e. isometric, dimetric and trimetric :
*How a projection of a drawing in axonometric projection is drawn.
*The different tilt planes in axonometric projection
*The methods of constructing axonometric scales
*Isometric projection drawings from a true diagonal
*Constructing the isometric tilt angle
*Constructing the diametric tilt angle
*The isometric circle and sphere in comparison to a circle
*Adjusting the isometric drawing methods for a circle to accommodate isometric projection
*The comparison of constructing isometric circles using the ordinates method and the 8 points method with respect to isometric drawing or projection.
*An analysis of the approximate 4 arcs method for isometric
*Drawing a sphere in isometric.
*The concepts of oblique projection :
*The comparison of constructing oblique circles with respect to cavalier or cabinet oblique.
*The 8 points method for oblique drawing as compared to the ordinates method for oblique drawing
*Drawing an ordinates method for cabinet oblique.
*Views of planometric drawings in 2 and 3 dimensions.
In Perspective projection:
*The concepts of one and two point perspective.
*The concepts of perspective drawing are discussed as paths or trajectories approach.
*The perspective range
*The receding direction
*The planes in perspective:
*Vertical and horizontal planes
*Picture plane
*Eye level plane
*Line of Sight plane
*SP to VP plane
*Methods of locating points in one and two point perspective
