Parent FAQs

Who can use BlocksCAD?

BlocksCAD was originally developed for students in 4th grade and above, but we've had second graders use it, and many adults who also use it successfully for 3D printed creations. Its precise geometric input requirements make it ideal for learning and for creating designs with strict tolerances like a replacement knob, or jewelry piece.

What resources are available for learning BlocksCAD?
