Module 5: CAD With Onshape
Use CAD to find interference, check reach, and compare geometry before fabricating parts. The lessons use Onshape because it runs in a browser and offers an education plan for FTC teams.

What This Unit Covers
Explain what CAD catches that a sketch on paper cannot.
Build fully defined sketches and turn them into parts with the core feature set.
Choose the right solid feature for a shape instead of forcing everything through extrude.
Drive a model from variables so one number changes the whole part.
Work with imported, surface, and mesh geometry that has no feature history.
Assemble parts with mates that move the way the real mechanism moves.
Pull vendor parts into your design instead of modeling hardware from scratch.
Review the sequence and goals here, then resume at your first incomplete lesson.
