Scripting in Rhino Python: Switching Units

Following up with the Scripting In Rhino Python series of articles, here is a useful snippet of code that automates switching units on a Rhino document.

This script basically switches the units of the current document between meters and millimeters. The important function is rs.UnitSystem(), which returns the current unit measure — or sets it if we give parameters to the function.

import rhinoscriptsyntax as rs

if rs.UnitSystem() == 2:
    # Current unit is mm, Switch to m
    rs.UnitSystem(4, False, True)
else:
    # Current unit is m, switch to mm
    rs.UnitSystem(2, False, True)
