MS: Nobson is projected across a paper surface. These are not perspective drawings, but adopt oblique projection, a particular kind of informal 3D rendering.
This is not the way our eyes see the world. There’s no vanishing point, no convergence of parallel lines on a point in the distance — parallel lines stay parallel, and the surface extends off into infinity, so there’s no horizon either.
Nevertheless these are architectural drawings combining plan, section, elevation into a rendered view. There’s a traditional term quite relevant here — ichnography — the ground floor plan that comprises the depiction of ichnoi — tracks or footprints, marks made by those no longer with us, paths that we may follow again. The term suggests that architectural drawing concerns matters of presence and absence.
