Cause KiCad embeds every footprint that your project uses into the board file. Each footprint stores a path to its 3D model(s). Paths to 3D models typically use a variable which expands to a real path. In KiCad 6, the 3D model path variable is ${KICAD6_3DMODEL_DIR}, which is set to the 3D model library location. In prior versions of KiCad, the correspond…
