CAD is not necessary for FTC to build a successful robot.

Many successful teams don’t CAD their robot at all. Other successful teams only make parts of their robot in CAD. Of course, few teams do fully design their robot in CAD, especially those that regularly show up at the world championship.

So, what’s the point of CAD, then? It is encouraged that new/rookie teams try their hand at CAD, especially if you have a mentor or parent who is experienced in such an area. CAD is beneficial for multiple reasons.

CAD solves a lot of preventable headaches, such as spacing issues. Thus, it will save time when you discover problems in CAD that you can remediate before you build your robot.

CAD is a professional tool that is used in many STEM fields. Having CAD knowledge and skills will be beneficial in your future career, should you study and work in those fields.

If you desire to create 3D-printed or machined parts, CAD will be necessary to do so.

However, CAD is not the magic genie that will guarantee you success in FTC. When used properly, it is a great tool to aid teams in building their robot. 

Keep in mind, though, that many teams have had success without CAD.
