The picture plane should never be placed behind the station point.

More Questions from Perspective Drawings

• Using CAD, you are typically able to select viewing distance, focal point, z-axis convergence, and arc resolution scale for perspective representations.
• Lines that are parallel to the picture plane remain parallel to one another and do not converge to a vanishing point.
• One-point perspective is also known as angular perspective.
• Shading pictorial drawings may lead to confusion when describing shapes of objects.
• Perspective drawings are classified according to their number of ground lines.
• Most CAD programs produce only wireframe, not solid perspective representations.
• The picture plane can be placed either behind the object or in front of the object.
• Parallel lines converge toward a single point on the horizon called the vanishing point.
• The vanishing point is the intersection of the ground plane with the picture plane.
• The horizon in the perspective view should be drawn at the same level above the ground line as the height of the station point.
