I would like to encourage you to take a look at Autodesk Inventor Publisher, to help showcase and communicate your designs. They say a picture is worth 1000 words; a Publisher animated assembly speaks a thousand times more.
Publisher supports the most common native CAD formats (Autodesk Inventor, CATIA, ProENGINEER, DWG (3D), DWF, STEP, IGES, and SAT).
Looking forward to seeing everyone’s results this season. Good luck all!
