❏ HB (or softer) pencil
Doing it the ICT way
If you have access to a computer and drawing software, you can quite easily enlarge and reduce
objects on screen. You need to be careful to keep the proportions of the object the same. If you
are stretching an object; it is easy to increase the horizontal dimensions more than the vertical
dimensions and vice versa. If you are using CAD software, this is not a problem. Scan in the
picture of the dinosaur and try to enlarge or reduce it with both drawing and CAD software.
