That's so true. Especially for working on the BOM - definitely saves time to have a visual reference at your fingertips.
Also, having CAD drawings can be very useful when talking to judges, pit scouters, and other people interested in learning about your robot. This comes into play very well during competitions when the robot is being worked on and parts of it are out of view. I also noticed that having a CAD drawing to look at helps me explain how things work on the robot. I'm not sure if this is true for everyone, but the drawings are still useful.
All in all, as was stated earlier, CAD drawings are not explicitly needed, but if you have the time and ability to make them, they can really help.
I hope this helps,
