use this powerpoint to draw irregular objects in perspective

1. Draw hour horizon line and vanishing
point, and an irregular object.

2. Connect the outside corners to the
vanishing point using the “Closing the
door” technique so that the lines hit the
outside edges.

3. If there is anything sticking out in
between the two lines you just
drew, connect a line to those too.

4. Draw your parallel lines to show the
back of the object, it should follow
the line in front.

5. Erase your tails.
