PARAMETRIC EDITS

From blank geometry
to finished parts.

Instruction-led tasks connect CadQuery script changes with STEP reference shapes and geometry checks.

SAMPLE PACKAGE

Every edit,
fully linked.

The sample has 15 STEP snapshots, 10 runnable CadQuery states, and nine script diffs.

THE TASK LIBRARY

Edits with
checkable outcomes.

Each task links a written instruction to a script change and geometry that can be checked.
