How to manage drawing illustrations in technical documentation (report, survey, etc)?
Could anybody hints me on how to draw these kinds of illustrations? I am always not confident of creating and combing those small pieces like computers, cables, laptops, sensors, and so on. Especially I want them all to look well-fitting.
And if I want to search the raw material of the pieces of the illustration, what is the keyword for them? Icon? Small gallery? Illustration picture?...
At last, what is the better tool for drawing illustrations, gimp or coreldraw?
Thanks very very much for you help!
