This article has covered the basis of a mixed mode, hybrid system in ZEMAX which incorporates a group of non-sequential elements in an otherwise sequential design.  Using the concept of ports, rays from sequential field points may be traced non-sequentially within a defined group of NSC objects.  Rays leave the group via the exit port, where the sequential based ray tracing resumes.
