How to Animate a Screw in a Fusion Assembly

When your need to animate a Fusion assembly that required the rotation of a screw, you notice one big limitation in the software.  You will find it is impossible to drive the rotation of a Revolve or Cylindrical joint more than 360 degrees without it resetting the linear motion of the screw.  In this video I demonstrate a process for driving one, or multiple, screws using another assembly joint, in this case a Slider joint.

The process requires the entry of a hidden Fusion text command which is shown in the video but I will list it here to make sure you can read it.  It is "Fusion.JointAnimationTime 25" (without the quotes) where the number represents the number of seconds you desire.  The default Fusion value is three.  This variable is returned to default when the application is restarted.
