Carving is a stereotomic procedure—like stacking and casting—that deals with the manipulation of solid form. Carving shapes solids through the removal of material. Architecturally speaking, carving can serve as both material procedure and conceptual metaphor in the development and elaboration of forms large and small. Forming a class of subtractive procedures—among them excavation, milling, routing, turning, boring, chiseling—carving is undertaken at a range of scales in the building process: from the cutting of a wood mortise or tenon to the massive manipulations of landforms; it engages tools of varying mechanical complexity and technological sophistication, from the simple blade of a plane or shovel to the robotic operations of computer-numerically-controlled 5-axis mill.
