My brother in law has a show that requires cad drawing. Many people do not even know what it is. My little one thought it was pictures of a car that travels people from place to place - “you know, the yellow and black car”. She thought that it was cab drawing. Kids really do say the craziest things. I actually didn’t know all that much about it until he started to explain his job. I still think that it would be more fun to just draw cabs all day long
