The rest position settings for each constraint
are located in the constrained object’s constraint attributes.
Enable Rest Position
If on, the rest position
is active for the constrained object. If off, the rest position
is inactive for the constrained object. Turning Enable
Rest Position off does not remove it from the constrained
object.
Rest Translate
Sets the X, Y, and Z
translation for the constrained object’s Translate rest position. These
fields are present for only Point and Parent constraints.
Rest Rotate
Sets the X, Y, and Z
rotation for the constrained object’s Rotate rest
position. These fields are present only for Orient, Aim, Parent, Tangent, and Normal constraints.
Rest Scale
Sets the X, Y, and Z
scaling for the constrained object’s Scale rest
position. These fields are present only for Scale constraints.
