[Property] conjugatePlateId [Optionality] Multiple Optional [Description] Refers to the plate on the opposite side of the plate boundary. At creation, a plate boundary will be assigned a reconstructionPlateId, which is effectively the plate that the boundary "belongs to". The conjugate plate is the plate on the opposite side of the boundary from this plate. In the case of the Isochron feature, a conjugate plate is the plate that the Isochron's conjugate is associated with. [Used In]
