How to use

  1. Select one or more objects you want to downgrade
  2. Press the Draft Downgrade.png Draft Downgrade button or press D then N keys


The selected objects are modified/downgraded, according to the following conditions (in order):

  • if only one object is selected and it contains more than one face, each face becomes a separate object
  • if there are more than one face in the selection, the subsequent objects are subtracted from the first one
  • if there is only one face in the selection, it gets converted into a wire
  • otherwise all wires found in the selection are exploded into single edges



The Downgrade tool can be used in python scripts and macros by using the following function:

downgrade (objects, [delete], [force]) 
  • Downgrades the given object(s) (can be an object or a list of objects).
  • If delete is True, old objects are deleted.
  • The force attribute can be used to force a certain way of downgrading. It can be: explode, shapify, subtr, splitFaces, cut2, getWire, splitWires.
  • Returns a dictionary containing two lists, a list of new objects and a list of objects to be deleted
