4.3.1 Design Concept
The following design concept incorporates nonobjective art in a state of pure expressionism in which the final object creates its own reality as Nevelson’s work is the inspiration for this project. This design incorporates 3 different simple objects which include a sphere, supermans symbol, a triangle. These objects are placed together to create an implied motion as they are placed together using overlapping composition. The isometric sketch shows how these 3 objects are placed together while giving a 3-dimensional view.
4.3.2 Design Iterations
The following Images show the positive model to make sure there are no undercuts and implementing fillets at all edges. For this model techniques such as extrude, revolve, and the sketch was used in order to create the 4 simple shapes to be joined together using the combine function. As well, some modifications to the design created flatter surfaces that would decrease the total depth of the object. The iteration shows how the beginning sketch was modified, from being only 3 objects to 4 totally different objects. The first object I made was the lightning bolt which used the extrude feature, the second object was oval-shaped which used half of an oval, and used the revolve feature over the y-axis to create the full oval shape, the third object was a sketch of a trophy stand also revolved around the y- axis and the fourth object was the triangle-shaped ring which also used the feature revolve around the z-axis.
Iteration 1
Iteration 2
Iteration 3
In the third iteration, I modified the design to look a little sharper and changed the size of the bolt, the ring, the stand, and the base. Before I moved to the Final negative mold, I had to fillet all the edges except for the base because the base is going to be slightly sticking out of the box.
4.3.3 Design Final
The final negative version of the object to be milled as a mold on the CNC router is shown below. The final design incorporates modeling implied motion and making a mold. Once I had the final design completed I created an 8″ x 8″ x 2″ box and placed the final object in the box, about 1″ deep, and did a cut of the final object to create a negative mold in the box.
