SketchUp Circular Timber-Slat Stair Tower in Line Drawing

A circular stair tower enclosed by closely spaced vertical timber slats, with a spiral flight winding up the inside edge and a slatted balustrade around the upper deck. Modeled in SketchUp (.skp) and drawn in simple outlines that show every slat. An interesting feature for garden pavilions, observation towers or resort landscapes.
