Bulge = the DXF encoding of a native arc inside a polyline: bulge = tan(¼ × included angle). Sign gives direction (+ CCW, − CW); the centre sits on the minor-arc side of the chord. These are the customer’s real, intended arcs — we preserve them exactly, never re-fit them from sampled points. (Re-fitting is only for curves the customer exploded into straight facets — see polylining.)
