CTC 312 Student Examples of Rendered Drawings (Spring 02)

Courtney C. (Mechanical Engr. Technology)

I drew a piece of square duct transitioning to a piece of round duct. I used a 24 x 24 inch square duct and a 20-inch spiral duct. I needed to figure out a way to construct the transition with all the proper curvatures and angles. The square duct and transition were created by creating separate surfaces and stitching them to make a solid part. The spiral duct was created by drawing a polyline in the side view with the thickness and length of the object defined. I then revolved the polyline on a circular path. There was not a material for steel so I had to choose another material for representation. I ran into many problems creating my surfaces and joining them all together to form the solid. The book did not help much. I ended up reading many of the help files and using trial and error to create things the way I wanted.

The world’s famous monuments and architectural sites have always inspired me. One of my future long-range plans is to see as many famous sites as possible. For years, I thought my first visit would be to Giza Pyramids in Egypt, because I used to live on one of the Egypt’s neighboring countries; however, I visited the Washington Monument in 1998 and it became the first site on my list. Therefore, I chose to draw the Washington Monument as my final project. I did some modifications, like cutting the surrounding circular wall to half-circular wall and putting a concrete slab under the monument. The drawing wasn’t hard because it is not a complex shape and has only a few members. However, rendering the frame was hard because there weren’t any materials that would make the design look like the real monument.

We chose to draw an architectural marvel, the Hulme arch bridge located in Manchester, UK and designed by Architect Chris Wilkinson. Watson steel carried out the engineering fabrication, corrosion protection and erection of the structure. The 28-meter high arch runs diagonally across the deck. The deck is supported by a total of 22 steel cables, 11 on each side of the carriageway. The amount of steel used in the bridge is about 365 tons. The bridge was completed in 1990, and it has won many prestigious awards. This was a challenging and interesting project.

Daniel M. (Industrial Engr. Technology)

For my final project I chose to draw a 3-D solid model of a machine vise. A vise is made of solid steel and is used in industry for the machining of small and intricate parts. The place cylinder and place slab commands were used to create many of the parts. I used the solid editing commands for creating the chamfer and fillets. Also, I used the union and subtraction commands on the parts that needed to be together. I used two main lighting schemes, both distance and spot lighting. One of the spot light positions can be seen on the rendered drawing.

My final project consisted of drawing a simple beam connection. The project was more difficult than I first imagined. The connection I modeled was taken from an old structural steel book. The most difficult parts of this project were modeling the beams that were cut away and figuring out how to use the texture and lighting.
