## Description
|
|
|
|
Named scalar parameter with optional physical-unit and tolerance intent.
|
|
|
|
``default`` and ``tolerance`` remain in their declared units. Evaluation,
|
|
geometry parameters, and tolerance propagation convert them to SimpleCAD's
|
|
canonical CAD units: millimeters for length and degrees for angle.
