The “Engineering Guru Package” contains the latest published InRoads works, plus both of the unpublished books that relate specifically to the Engineer, Technician or Designer.
(This package does not contain information on the Survey side of the software, which means that this package is exactly the same as the “Illuminations Package” but it does not contain the InRoads Survey book.)
