CAD 200 (Contributor)

Prereqs: CAD 100 → CAD 100 (prerequisite)

Duration: ~4–6 weeks (mid-build season)

Required Reading​

  1. CAD Standards — Onshape conventions and best practices
  2. Module 3: Design for Manufacturability (DFM) — Cost-effective design and tolerancing

Tasks

  • Build a small subsystem assembly with motion; check clearances/interference.
  • Produce a drawing pack (PDF + DXF/STEP) with BOM and notes.

Sign-off

  • Mentor verifies mates, clearances, and release-quality drawings/exports.

Best practices

  • Use mate limits to reflect real motion; run interference checks.
  • Produce clean drawings with BOM and notes; export DXF/STEP.

Common mistakes

  • Over-constraining; missing clearances; stale exports.

Checklist

  • Assembly with motion and clearances checked
  • Drawing pack + DXF/STEP + BOM ready

Evidence to attach

  • Assembly file and simplified config (if used)
  • Drawing pack + DXF/STEP exports + BOM
  • Interference/clearance check notes
