ANSWERS TO PRACTICE EXERCISE
One-point exists when two dimensions of an object height and
width are parallel to the picture plane.
Two-point exists when the object is sitting at an angle to the
Three-point exists when none
parallel to the picture plane.
To establish the needed station point and vanishing points.
The station point.
The vanishing point.
Step one is to draw a line to represent the picture plane.
Step two is to select the station point (approximately the center
of the plan view at a 30 overall angle).
