Call the feature on uppermost level via context menu command Insert Fixed plane.... This command is only available on part level.
Example with translation and rotation:
If, for example, a connection point shall have another orientation of coordinate system than the original, this can be achieved by a fixed plane.
In example shown below the original X axis is laid on the Z axis (Z=1) and then the original Y axis on the x axis (X=1). Now connection points set with standard values on the absolute plane have a new orientation.
