I would claim that it isn't necessary but it certainly makes it easier. Hand drafting is still a perfectly viable way of designing a product. I think what Alex could have said was that CAD is not necessary for working through the rough stages of an idea.
Regarding this entire thread, Instead of doing 40 different chassis please consider doing a couple chassis with several revisions of each. I like the concept of giving yourself a short time line as it will increase your skills but I think this would be a better use of time if you got something you could use out of it.
