The term “pathworking” comes from the practice of Kabbalah, and refers to working with the 22 paths of the Tree of Life.
However, the word has since entered common parlance and is now used to refer to any working with a specific group of spirits.
For example, in his book Evoking Eternity, EA has specific groups of angels and demons one would work with for spiritual Ascent, that he refers to as a pathworking.
In Hargrove’s book, as well as the books “Raziel’s Paths of Power”, and “Lucifer and the Hidden Demons,” you are “pathworking” the Goetia, the 72 Angels of the Shemhamforash, and Lucifer’s legions, respectively.
The technique of using visual imagery as a method of contact is most often referred to as “visionary magick,” and it seems to be mainly used in the system of Enochian Magick, for travelling the 30 Aeythers, as far as I can tell. That is where I first encountered it, anyway.
Damon Brand also uses it in his Archangels of Magick book, in which he refers to the images as “Evocation Keys.”
