The practice of designing and constructing systems, structures, or portals that function in the spaces between dimensions, requiring materials that exist in no dimension and construction techniques that violate every known law of physics. Interdimensional engineers must work with "gap materials" that have properties only in the undefined spaces between realities, assemble them using "non-local tools" that exist everywhere and nowhere simultaneously, and test their creations using "void protocols" that assume failure is the default state. The field attracts people who found regular engineering too limiting and decided that building things in nonexistent spaces was the logical next step.
Interdimensional Engineering Example: "She was an interdimensional engineer who designed a bridge across the gap between the 3rd and 4th dimensions. The bridge existed only in the space between, visible from neither side, usable by no one. She considered it a triumph of pure engineering—a structure that served no purpose, occupied no space, and required no maintenance. It was, in every way, perfect."
