CURVES - created from points - lines, polylines, splines - multiple segments - can be 3D like wires - cannot be 3D printed SURFACES - created from curves - within edges/boundaries - open and without thickness - cannot be 3D printed analytic/mathematical model: built from points, curves and surfaces constructive, geometrical, consistent, editable/measurable exact editing through points, curves and defined parameters applications: industrial processes / CAD / CAM / CNC turning, milling, lasercutting.
