Notes

The default gear(s) are displayed like this:

To display the cam disks and the set of rollers (pins) in different colours, we need three identical HypocycloidGear objects. Their visibility can be toggled:

  • Datashow_disk0 (Bool) for the main cam disk.
  • Datashow_disk1 (Bool) for a reversed cam disk on top.
  • Datashow_pins (Bool) for the set of pins.
