Virtual Axis

Use the Virtual Axis Joint command to create joints and cams. Use this to create linear or angular joints without assigning geometry. Use a virtual axis as the master axis to reduce disturbances on the physical slave axis.

A virtual axis is useful when you need a clean, disturbance-free motion reference (for example, a master cam profile driver) that does not need to correspond to real geometry in the assembly — the physical (slave) axis can then track it via a coupling relationship.
