Model a Double Negative Space, Three Ways 


Screenshot  
This exercises practices basic 3d modeling skills by creating three abstract "double negative" spaces using three methods: solid modeling, lofted surfaces and sweep surfaces.

Create three different "Double Negative" models exhibiting the following three methods. The original solid cube should measure 8" x 16" x 4". All three examples should have intersecting voided space that approximately take up 50% of the original cube, showcasing evocative spatial qualities inside the model. Each method should be located on a separate layer.
 Method 1  Solid Modeling
 This form should be generated using rational geometry, selecting forms of your choice.
 Method 2  Lofted Geometry
 This form should be generated using curved, lofted geometry created by serial sections of your own design.
 Method 3  Sweep Surfaces
 This form should be generated using the Sweep command, with a rectangle that is extruded along a continuous polyline that travels through the space of the cube.
Final models should be saved in ONE rhino file (.3dm).
