Engine verification console

Locally executed deterministic geometry and rendering checks. No external services or telemetry. This evaluates ideal kinematic models—not manufacturing interference, stress, loads, tolerances, or browser/device compatibility.

Reports are generated from the same engine and render modules loaded by the live workbench. Renderer tests cover geometry and text strokes plus SVG and R12 DXF output; they do not validate a downstream CAD application's import behavior.
