Is there any difference between CAD construction drawing and hand-drawn construction drawing of the same building?

Theoretically, it should be exactly the same, because CAD is to simulate people's manual drawing with a computer. But in practice, there are differences. CAD is finer, manual drawing is more flexible, and manual drawing is faster in local simple drawing. For example, the dimension division mark CAD is oblique, and the manual drawing can be oblique or round, such as the legend filling of concrete or pebbles. Drawing by hand is more perfect. Generally, the revised drawings after proofreading, including review and countersignature, are generally manually revised. Unless there are major problems, drawings will not be re-drawn, so as to save drawing time.
