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)
