CAD programming is a bit complicated for younger students, but many of them have mastered Minecraft. Printcraft is a program that allows users to 3D print anything they create on Minecraft. What a fun way to introduce 3D printing!
At the start of 2015, I picked up Rhino as my second CAD program. I started a series of fun modeling experiments to practice form fluency in the program as well as quick KeyShot rendering compositions.
