The document provides instructions for drawing the perspective views of two objects: 1) A square pyramid with a base of 30mm resting on the ground plane. The station point is 70mm in front of the picture plane and 40mm to the right of the pyramid axis and 60mm above the ground. 2) A 30x20x15mm rectangular block lying on its largest face with an edge parallel to the picture plane at a 30 degree angle. The station point is 50mm in front of the picture plane and 30mm above the ground in the central plane passing through the block center. The steps provided include understanding the reference planes, drawing lines of intersection, rays from corners to the station point, visible/

8. Draw the perspective view of a square pyramid of base 30 mm, side
and height of apex 45 mm rests on GP. The nearest edge of the base is parallel
to and 20 mm behind the picture plane. The station point is situated at a
distance of 70 mm in front of the PP and 40 mm to the right of the axis of the
pyramid and 60 mm above the ground.
• Understand and visualize the reference planes and
object placed on GP.
• Understand and draw the line of intersection of the
planes, object and observer in TV and FV.
• Draw the rays connecting object corners and SP in
TV and FV.
• Draw the visual rays connecting object corners
and SP in TV and FV.
• Mark piercing points of the visual rays in top view
and project and mark them to the corresponding
rays in front view.
• Join the points, draw the visible and hidden edges
to complete the perspective projection of the pyramid.

11. A rectangular block 30 × 20 × 15 mm is lying on the ground plane, on
one of its largest faces. A vertical edge is in the PP and the longer edge
containing that face makes an angle of 30° with the picture plane. The station
point is 50 mm in front of the picture plane, 30 mm above the ground plane
and lies in the central plane which passes through the center of the block.
Draw the perspective view of the block by vanishing point method.
• Draw TV of the block and rays
connecting object corners and SP.
• Draw a line passing through SP
and parallel to an inclined edge of
the solid to mark vanishing points.
• Draw the perspective of the edge
of the rectangular block which
touches the PP.
• Mark the piercing points of the
rays in TV and project them to FV
• Join visible and hidden edges to
complete perspective projection.

13. A rectangular block 30 × 20 × 15 mm is lying on the ground plane, on
one of its largest faces. A vertical edge is in the PP and the longer edge
containing that face makes an angle of 30° with the picture plane. The station
point is 50 mm in front of the picture plane, 30 mm above the ground plane
and lies in the central plane which passes through the center of the block.
Draw the perspective view of the block by vanishing point method.
• Draw the TV and rays connecting
object corners and SP.
• Draw a line passing through SP and
parallel to an inclined edge of the
cube to mark vanishing points.
• Draw perspective of an edge of
cube by using the line of true
height.
• Mark the piercing points of the rays
in TV and project them to FV
• Join visible and hidden edges to
complete perspective projection of
the cube.
