About
A self-supporting arch surround: two 1.7 m piers on spread bases carrying an eleven-voussoir semicircular arch over a 1.8 m by 2.6 m opening, 0.4 m deep. Dimensions 2.40 x 2.84 x 0.50 m (X x Y x Z). Origin at the centre of the opening on the floor datum; the arch springs at 1.70 m. Metres, +Y up, +Z front, ground contact at y=0. Free standing. Butt a 2 m or 4 m wall to either pier at the wall-end ports. Connectors: west (wall-end), east (wall-end). Neutral greybox palette for prototyping before art exists. Static geometry; no skinned rig, collision or navigation data.
