Version 7 affords many advanced modeling techniques previously impractical or impossible. Instead of a basic two-step beveled cube, I prefer to use "Just Another Method." 1) Add a Cylinder Polygon Object to scene 2) properties: Sections longitudinal = 4 Sections height = 1 Sections ground = 1 Radius = 0.5 Height = .707 Cover = None 3) Rotate X Axis –315º 4) Make Editable 5) Go into Polygon Mode Right click – Polygon – Fill Hole – add top and bottom polygons 6) Right click – Object Info – Watertight? Yes 7) Add a Polyhedra Polygon Object to scene Properties: Radius = 0.5 Type: Octahedron 9) With Octahedron selected, go into Object Mode 10) Scale up the octahedron X = 1.707, Y = 1.707, Z = 1.707 11) In the Object Browser: Add a Boolean Creator Drag the Cylinder and Polyhedron to be children of the Boolean Creator 12) Select the Boolean Creator 13) Properties: Operation = Intersect Multi-Knife = checked 14) Make the Boolean object editable Voila! A Watertight Cylinder-Octahedron Boolean-Intersection Polygon Object! Which technique provides superior results? You decide.
