SEE Electrical Expert has a more complex set of methods for deciding how elements are handled in the drawings. It also links into PLM and 3D harness modules to continue other parts of the design. Also, if you’re working as part of a large project, SEE Electrical Expert may be specified and an environment containing all the expected standards and symbols may have been produced. This can save a whole load of time setting things up. This is less likely with See Electrical, which is a lower cost control system design package, though very capable in itself.
