# Example of exporting a cadquery object to STEP using FreeCAD
#
# `FreeCAD` python module doesn't allow working with colors. For this
# we need the `FreeCADGui` module and to be able to access to objects
# `ViewObject` property. We are going to initialize FreeCADGui like
# usual, but instead of actually showing the window we will hide
# it. Note that We won't ever start the main loop at all.
