I tried my hand at drawing products and found Corel very useful for this task. Some of these components were drawn directly from the measurements of the item itself, and for the varying text on each of them I selected the closest one from the 700 fonts installed on my computer and modified them as necessary. I've found that more and more there are companies that utilize existing fonts for their logos because they are far easier than the old method...drawing them from scratch. These components are from an audio system that I have installed in one of my cars, and I have the full layout illustrated on another page.
