The gravity is one of the parameters taken into account during the dynamics simulation of a
mechanism.
By default, the gravity has an acceleration of 9.81 m/s2 along the Z axis.
Important:
The gravity definition is shared by all assemblies and is stored in a CATPreferences file. The
modification of the gravity definition affects every mechanism.
Once the CATPreferences file created, the 3D arrow representing the gravity definition still appears in Mechanical Systems Designapp.
