CAD Drawings CAD makes it really easy to generate geometric shapes. CAD makes it really easy to generate geometric shapes. Because of the ability for CAD to draw perfect elements and create angles, we never have to worry if drawings are coming out with inaccurate measurements. Because of the ability for CAD to draw perfect elements and create angles, we never have to worry if drawings are coming out with inaccurate measurements. This is not to say we do not check ourselves, but we know that if we type in 30 degrees, the angle will be a perfect 30 degrees.
