![]() The precise coordinates of every line, curve, corner, point, and every other object are all knowable from within a CAD drawing, and herein lies one of the chief advantages of CAD over hand-drafting. When you draw inside a CAD program you are not simply drawing, you are also simultaneously plotting every aspect of the projected concept in very fine detail. Reality brings with it many constraints that art ignores, and this is where CAD suddenly becomes useful. They then must switch hats and have to figure out how to make their concept into a real building, machine or other useful object. It would be almost impossible to build a correct building or engine from a strictly artistic depiction - and if you did build such a structure the result would likely turn out to be cartoony or unsound.Īrchitects, engineers and other creators play the role of artist, inventor or problem solver (usually all at once!) at the beginning of a project and get to have the fun of designing pretty spaces or marvellous things. In art the concept of scale is arbitrary and often deliberately warped to suit the needs of the particular art. ![]() The longer reasons are so varied that you are likely to get about 200 detailed answers if you ask 100 engineers, designers or architects.ĭrawing for engineering purposes is a lot different than drawing for art. ![]() That you are reading this means you probably already knew that.īut why use CAD? The short explanation is that CAD automates away many precision functions that are necessary for engineering drawings. ![]()
