# Pantograph scaling
# Scope: Ideal geometric scale mapping on one axis.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

inputTravel = 50 mm
inputArm = 100 mm
outputArm = 200 mm

scale := outputArm/inputArm
outputTravel := inputTravel*scale [mm]

check travel budget: outputTravel <= 120 mm

scenario alternative: inputTravel = 40 mm
