  • Ask these questions of the audience:Do you model your robot?How many model only for marketing or documentation?How many actually model for design?
  • The “D” in CAD is for “Design” not for “Documentation”Have you ever bought parts that you don’t use? Ever had to throw stuff away because you cut it and then the design didn’t work?CAD as dual-use – design and documentation
  • There are lots of CAD packages out there, we are only going to talk about Fusion360 (we are biased)Show the dashboard

  • FIRST Fair 2013 Using CAD to improve your FRC design process Manjiri McCoy and Jeff Strater SW Engineers, Autodesk © 2013 Autodesk
  • Topics for today      CAD in the FRC design process Why you should use CAD Tips for simplifying CAD process Autodesk Fusion360 introduction Online resources © 2013 Autodesk
  • CAD in FRC © 2013 Autodesk
  • CAD on your team  Do you make CAD models at all?  If so, what is it used for? Just documenting the design that you already built?  Or, do you actually design parts of your robot before you build it? © 2013 Autodesk
  • Why use CAD for Design?  You can avoid problems before they happen     Too heavy Dimensions are too big Mechanisms don’t work as you thought they would Components are “in the way” that nobody realized until you tried it out  It’s cheaper to model in software than in hardware  Parts list for purchasing  This is how real businesses design stuff  You can make really cool marketing/documentation as well © 2013 Autodesk
  • But, it’s too hard to model the whole robot – that would take forever!  Don’t model the whole thing  Only design the parts that are critical to success, or that you have concerns about  If you are re-using the drive train from last year, don’t model that, just model the parts that are critical to the game  Don’t model in too much detail  Tire treads are not necessary for analyzing your design  Use the internet  There is a lot of designs out there that you can use  GrabCAD  FIRST  Parts manufacturers  Divide up the design among multiple team members © 2013 Autodesk
  • Autodesk Fusion360 © 2013 Autodesk
  • Using Fusion360 for your designs  What is Autodesk Fusion360?     Cloud-based CAD for collaboration Direct modeling and a simple, modern UI Runs on Windows and Mac Support for mechanical joints to make mechanism design simple  Fusion (and all Autodesk software) is free for students © 2013 Autodesk
  • Fusion 360 features of interest:  Collaboration with a team  You don’t have to share computers or thumb drives to have multiple team members work on the same design  Even a single team member can work on the design at school, at home, anywhere.  Mechanism design  Fusion’s Joint command allows you to create mechanisms very quickly  Motion Link and Motion Study © 2013 Autodesk
  • More Fusion features  Interference detection  Can determine if parts collide  Contact sets also useful for this  Mass properties  Can show overall weight, volume, center of gravity © 2013 Autodesk
