In this video, see step by step how to draw the projections of a pentagonal prism resting on its base, when it is tilted so its axis is inclined to both the HP and the VP — using the change of position method. Shown first in 3D with the reference planes, then as the 2D front view and top view.
What you'll see:
Pentagonal prism resting on its base on the HP, with a base corner pointing to the right
Simple-position front view (rectangle) and top view (pentagon)
Tipping the prism onto one base corner until the axis makes 30° with the HP
Front view and top view in this tilted position
Rotating about a vertical axis through the resting corner so the axis also makes 40° with the VP
Final front view and top view in this position
