Try solidworks. It's the only one I learned in engineering school but is really intuitive for a CAD (autocad sucks, but that's because it was hard for me and I never learned it).
Also sketchup will give you the fundamentals for free.
I'd say it is worth it to learn the basics of anything you'll be having employees do for you. It's good to know what you're asking for and the scope so that you can connect to your employees more easily. I wouldn't become an expert at it though if you are not planning on using it too much.
