Parametric modeling quick deck
Recall core parametric modeling habits that protect CAD design intent.
PDSA for CAD PDSA What does PDSA look like in parametric modeling? Plan, build, test, repair. Constraint What should a constraint express that a plain dimension may hide? A relationship that should remain true: centered, tangent, equal, parallel, concentric, symmetric, or coincident. Dimensions size geometry; constraints explain design relationships. Feature order Which feature order is more robust? Keep cosmetic or edge-identity-changing features late unless they are genuinely functional. Objection The sketch is black, so why test it? A teammate wants to move straight from fully defined sketch to drawing. Your line Black tells us degrees of freedom are closed. The…
