Drawing the Vanishing PointsDraw a Horizon Line and select two Vanishing Points as shown.
Draw the front edge of the box as a vertical at a suitable position ( remember that verticals remain vertical throughout this exercise).

Construction LinesDraw construction lines to the Vanishing Points as shown.

Construction LinesDraw the two rear edges, remember that these are vertical.
Choosing where to place these can be difficult as measurements in perspective are not accurate. Use the idea of “ Good Proportion “ to decide where they go.

More Construction LinesDraw the remaining construction lines as shown.

Finishing offComplete the outline of the box.
The box may look very distorted and unrealistic if the vanishing points are placed too close together or if the box is too close to the front edge of the paper.

More Boxes
If there is a line of boxes, such as the outlines of kitchen cabinets or terraced houses, it can very difficult to estimate where the verticals are to be placed.
Fortunately, there is a simple fact which will help.
The centre of the side of the box is where the diagonals of that side cross.
The next few slides show how to use this.

More BoxesDraw diagonal construction lines on the side of the box and then draw a construction line through the centre of that side to VP2 as shown.

More BoxesThe point labelled C is the centre of the upright ACB and is the middle of two combined boxes.

More BoxesDraw a construction line from D through C.
The bottom corner of the next box is where this line meets the construction line from B to VP2.

Finishing offComplete the outline of the second box. Note that it probably looks much smaller than you might have drawn it just using your “ Good proportion “ rules.

Lots More BoxesOnce you have got this idea, you should have no problem drawing streets of houses.

More Complicated ShapesThe boxes you have drawn can make crates for more complicated shapes.
The problem comes with shapes that involve curves, start with a circle which is drawn inside a square crate.
Draw the front edge of the crate and produce perspective lines back to VP2.

Drawing a CircleThe foreshortening effect that you want to achieve requires an artistic decision.
How far along the perspective line are you going to place the right hand side of the square – ensure that it is less than the height of the square and make up your mind.
Here, the height is 6 cm and the distance along is about 5 cm.

Drawing a CircleLocate the centre of the circle by using the intersection of the diagonals and draw construction lines to find where the circle touches the crate as shown.

Drawing a Circle
Sketch the outline of the circle in a realistic way – this is not easy…
© J Lewis 2004
Drawing a CircleNotice that using the idea of splitting the diagonals into three equal sections to give extra points on the circle gives a reasonable result and is very quick.
© J Lewis 2004
Drawing a CylinderIf the circle is the end of a cylinder, project back towards the other Vanishing Point and complete the drawing as shown.
