Let the fun and games begin! While continuing the dynamic learn-as-you do method of teaching this book is the first to actually challenge the students' critical thinking skills to come up with their own designs for the final Galactic Ship project. The student will learn how to create their own dice, dominos, tic-tac-toe, cube puzzle, Geenga blocks, and Galactic Ship game projects. The book introduces students to the concepts of: the Cartesian coordinate system that describes three-dimensional space, conversion of inches to millimeters, how to use the Part, Part Design and Draft workbenches in tandem to create objects, how to go in and make changes to objects that they have already designed, how to export .STL files, how to use Netfabb Basic to check .STL files for errors, and 3D printer slicer settings. FreeCAD’s ability to be downloaded and ran without connection to the Internet allows it to be a terrific resource for any STEM education project worldwide.
