Engineering with CAD
Parametric CAD: things that fit other things.
What students learn
Professional parametric CAD. Sketches that drive geometry, constraints, assemblies, design-for-print (overhangs, tolerances, supports), slicer settings that actually matter. The bridge from "shapes in a browser" to "things that fit other things."
Parametric CAD mental model. Design-for-manufacture instincts. The ability to read a real engineering drawing. Iterating across print-measure-fix-reprint cycles.
Module-by-module
-
01
Sketching with intent
Sketches, constraints, dimensions. Parametric box that resizes cleanly.
-
02
3D operations
Extrude, revolve, sweep, loft. Cylindrical container with snap-fit lid.
-
03
Assemblies
Multiple parts, joints, motion. Robot gripper that opens and closes in CAD.
-
04
Design for print
Overhangs, tolerances, fillets, supports. Printable model + plan.
-
05
Slicer deep-dive
Layer height, infill, supports, retraction. Tuned print profile.
-
06
Iteration loop
Print, measure, fix, reprint. Three versions of one part.
-
07
Mid-project: real problem
Student picks something to fix at home. Working solution.
-
08
Documentation
Drawings, dimensions, BOM. Engineering drawing pack.
-
09
Final project, part 1
Multi-part assembly. CAD complete.
-
10
Final project, part 2
Print and assemble. Physical demo + design review.
What they make
A multi-part 3D-printed assembly that solves a real problem at home or school.
Walk away with
Parametric CAD mental model. Design-for-manufacture instincts. Engineering-drawing literacy.
