Chapter 2 — Sketching Entities · relations · dimensions · the three states · design intent (Weeks 2–3)

Drill 1 · Name That Relation

Which sketch relation does each description call for? Check when done.

Drill 2 · Read the Sketch State

In the software these show as colors. Match each situation to its state. Check when done.

Tool · "Am I Fully Defined Yet?" Counter

Degrees of freedom in a simple sketch

A rough guide: each sketch point has 2 DOF; each relation or dimension removes some. This counter is a teaching estimate — the software is the real judge.

Result appears here.
Anchor to the origin first, then add relations for the geometry's logic (equal, symmetric, tangent), then dimensions for its sizes. Drag-test to find what is still loose.
