Parametric Lounge Chair — DXF developed by DraftEdge Engineering for industrial production. The model is fully parametric — every driving dimension is exposed in a clean, well-named feature tree so the design can be re-sized without rebuild errors. Design intent focuses on manufacturability: wall thicknesses, radii and tool access were validated against standard cutter geometry, and all mating faces carry explicit tolerances referenced to a single datum scheme. The package ships with production drawings, neutral exchange formats and a CAM-ready solid body, so the design can move from download to shop floor without remodelling.
