Inventor to reality

So we're 2 days into our week one regionals. We've used the robot, (hopefully) gotten it working, and basically tested/used all mechanisms. So where am I going with this? Here's where. Looking at the robot today I realized an amazing fact: we did it. We just emulated a proffesional engineering system, using CAD to create a working mechanical device for a purpose. We just started from ground up, and using CAD, designed, tested, and fabricated omponents ON A WORKING MACHINE. What we're doing here is not just a milestone, it's a milestone going into a life skill.

So what are all your thoughts? Was the use of Inventor helpful (as it was for us)? Was it a worthwhile step to take? Have you seen your drawings take shape?
