How to Draw - Basic Linear Perspective

Step 7 A perspective on boxing

Place your ruler on the vanishing point and connect lines to all of the corners of the rectangles you just drew that don't require drawing a line over the face of the rectangle (see secondary image). If done correctly, you should have just drawn 10 diagonal lines.

Starting with the rectangle above both the horizon and vanishing point, draw a horizontal line connecting the diagonal lines. This should complete the box. Erase all unnecessary lines.

Next find the rectangle that is also above the horizon (but not above the vanishing point). Draw a horizontal line between the diagonals projecting from the bottom two corners and the vanishing point. At the point where the right diagonal line meets the newly created horizontal line, draw a vertical that connects to the diagonal that has been drawn from the top corner of the square. You should now have something that looks like a box. Erase all excess lines until you have a clean box.

Now, with the rectangle below the horizon, you are going to do similarly. Create a horizontal connecting the diagonals coming off the top corners and then drop a vertical from this intersection to the line drawn from the bottom corner.

The rectangle on the right should be completed in a similar manner to the one shown in "Step 5"

You should now have 4 new three-dimensional boxes.
