1. A system for a screed assembly of a paving machine, comprising:
a plurality of screed plates including at least a first screed plate and a second screed plate;
a screed frame coupled to the paving machine and at least one of first screed plate and the second screed plate;
a first plurality of sensors mounted to a major surface of the first screed plate;
a second plurality of sensors mounted to a major surface of the second screed plate;
a device configured to create a physical phenomenon that is detectable by the first plurality and the second plurality of sensors; and
a controller configured to, based on a detected position of each of the first plurality of sensors and each of the second plurality of sensors relative to the physical phenomenon, determine a relative position between the first screed plate and the second screed plate including a degree of parallelism between the major surface of the first screed plate and the major surface of the second screed plate.
