class VelocityBaseMotionBCState(BoundaryConditionState):
    """The VelocityBaseMotionBCState object stores the propagating data for a velocity base
    motion boundary condition in a step. One instance of this object is created internally
    by the VelocityBaseMotionBC object for each step. The instance is also deleted
    internally by the VelocityBaseMotionBC object.
    The VelocityBaseMotionBCState object has no constructor or methods.
    The VelocityBaseMotionBCState object is derived from the BoundaryConditionState object.

    Attributes
    ----------
    amplitudeState: SymbolicConstant
        A SymbolicConstant specifying the propagation state of the amplitude reference. Possible
        values are UNSET, SET, UNCHANGED, FREED, and MODIFIED.
    status: SymbolicConstant
        A SymbolicConstant specifying the propagation state of the :py:class:`~abaqus.BoundaryCondition.BoundaryConditionState.BoundaryConditionState` object. Possible values are:
        
        - NOT_YET_ACTIVE
        - CREATED
        - PROPAGATED
        - MODIFIED
        - DEACTIVATED
        - NO_LONGER_ACTIVE
        - TYPE_NOT_APPLICABLE
        - INSTANCE_NOT_APPLICABLE
        - PROPAGATED_FROM_BASE_STATE
        - MODIFIED_FROM_BASE_STATE
        - DEACTIVATED_FROM_BASE_STATE
        - BUILT_INTO_MODES
    amplitude: str
        A String specifying the name of the amplitude reference. The String is empty if the
        boundary condition has no amplitude reference.
