3D model made from primitives and splines with editable modifiers, of course, tubular frame with generatrix spline. Group objects and ordered by name for an easy selection. Similar objects and modifiers are instances, logical construction to facilite the edition. Interchange or edit materials directly from the material editor. Available in standard and vray (V-ray 1.50 SP1) materials: polished chrome (special metal for screws), and uphosltered by Spinneybeck black leather from procedural textures. It’s dimensions are 470x600x800mm (WxLxH) like the original, now made by Knoll furniture manufacturer. Minimum number of polygons for an accurate performance in Architecture scenes. Also, scene renders with HDRI map.
Note: adjust performance or quality editing the interpolation of spline at tubular frame, and/or fitting sides of primitives at boolean from screws. Also, you can fit 'Face Thresh' amount at optimize modifier of the screws. Recommended default configuration for quality and high quality indoor scenes.
