For simple blocky objects, such as a cube, you start by drawing the front as you would draw the front view/elevation of an orthogonal drawing
NOTE: This is similar to a PLANOMETRIC DRAWING click here where you start by drawing the top/plan view of an orthogonal drawing
To give depth to your drawing you then draw the receding lines at an angle - they must be parallel to each other. The angle can be any angle (as long as it is the same) but is usually one of the above angles because you can easily draw them with a set square
Remember that an OBLIQUE DRAWING is a PARALINE DRAWING
HOW FAR BACK DO YOU GO?
The length of the receding lines can be the actual depth of the object (according to the scale being used) and this is called CAVALIER OBLIQUE see below . However this gives a very distorted view of the object. It appears that the cube below goes back too far.
Remember that we are used to seeing things in PERSPECTIVE click here
Why is it called 'cavalier'?
To compensate for this distortion, CABINET OBLIQUE see below is generally used. The length of the receding lines is half the actual depth.
CABINET OBLIQUE is used particularly in cabinet making so that the cupboards, benches, etc. being drawn do not look out of proportion click here |
