This playbook runs through "a 40×30×8 mm base plate + a central Ø10 mm through-hole": qwen3.8-max turns a one-sentence requirement into a cadquery modeling script, the local kernel executes it and exports STEP/STL, and prints a volume check—the model volume matches the analytical value with zero error, turning modeling from clicking a mouse into writing requirements. Call chain: qwen3.8-max (requirement → cadquery parametric modeling script) → local open-source CAD kernel (cadquery) executes → exports STEP/STL (local execution does not consume Credits).

Real output

Ran through "a 40×30×8 mm base plate + a central Ø10 mm through-hole"; the 3D projection exported by cadquery and the volume check:

Model volume(mm³): 8971.681469
Analytical volume(mm³): 8971.681469
Difference(mm³): 0.000000
Relative error: 0.000000%
(Exported files: bracket.step 20KB · bracket.stl 26KB)

Step: one-sentence modeling

Send the prompt below to qwen3.8-max:

Write a Python cadquery script: build a 40×30×8 mm base plate, drill a Ø10 mm through-hole in the center;
export bracket.step and bracket.stl; and print the model volume and the analytical volume
(40*30*8 − π*5²*8) for comparison.
Only output complete, directly runnable Python code.

Notes

Consumption: This playbook involves text generation (qwen3.8-max, generating a cadquery modeling script); the local script execution that exports STEP/STL does not consume Credits.
Precision: In real testing the model volume matches the analytical value with zero error (0.000000%), geometrically exact and directly usable for downstream manufacturing.
Division of labor and prerequisites: The model is only responsible for generating the script; export is done by the local kernel. Before running, install the kernel first (pip install cadquery, a standalone virtual environment with Python 3.10+ is recommended). This example uses the open-source kernel cadquery; for similar use you can swap in Blender / FreeCAD MCP.
