CTC 312 Student Examples of Rendered Drawings (Spring 01)

J. Bruzee

I decided to “design” a bridge. The banisters, top railings, floor side rails, and each of the floorboards were placed using the “place slab” command. After the main part of the bridge was laid out I decided to lift the bridge off the ground and add stairs on each end. I placed two slabs that could be used for grass and a slab that could be used for the stream running under the bridge. The last thing I did was to chamfer the end handrails and the edge of the steps on the bridge. I thought this was a really fun project to do. When I started I was not sure that I could finish it, but now that it is done, I am really pleased with the results. You are able to see each of the individual boards in the floor of the bridge and you are able to see through the handrails. Every element of the drawing works well together.

This is my interpretation of an April sunset, seen through the center span of the Charles River Bridge. This is an amazing new bridge that is currently being constructed on the Central Artery, which cuts through the heart of Boston. My previous employer was responsible for the inspection of the pre-cast concrete panels that made up the driving surface of the center span. I was personally offered the 18-month job of inspecting these panels where they were made, in a pre-cast plant in Virginia. I turned it down to go back to school. And here I am.

I started with the pre-cast concrete panels that make up the driving surface. I have plans for these, so I drew them to the nearest foot. The other dimensions were inferred. The slabs were left red to show contrast. The only difficult part was crunching numbers to figure out precise locations.

The object I chose is a basic log home design. The foundation is a concrete slab; the walls are 9-inch diameter pine logs. The interior is designed for the possibility of one to four bedrooms. The center section is designed to house the kitchen in the backside and the living room area toward the front section. Not shown in my design is the two-way fireplace that divides the kitchen and dining areas from the living room. I had a great time creating this project. My experience doing this has greatly increased my respect for those whom do three-dimensional design with computers.

For the final project I decided to draw a beam-to-column flange connection; and at the end of the column, there is a base plate. The beam and column were built using smartline and accudraw. The beam was drawn in the front view and the column in the top view. Then I drew an angle that was used to make the connection from the beam to the column. To get two that were exactly the same I made one and then mirrored the original. I moved the objects into the right place once they were all drawn. I added a base place to the bottom of the column and constructed a fillet to make a weld at the bottom of the column to the base place. The material that I used was iron because the material palette did not have steel to select from. Source and global lighting were used.

I designed a 6’ x 7’ concrete box culvert with reinforcing bars in the concrete. About 90% of the project was done in the front view, and when it came time to extend the materials and render, I worked in the isometric view. The box structures were added first and the reinforcing bars were added last. I used global lighting to show the shadows.

I put in many hours on this project. I had problems setting the active depth and the display depth. I think that the source of my trouble was I missed most of the presentations on 3D topics due to circumstances beyond my control. My daughter decided it was time to be born. Once I was able to set the active and display depths where they needed to be, the rest of the drawing was pretty simple. The material used for the retaining wall was block-split face from the masonry palette.

My final 3-D drawing represents a cut section of a roadway. I created boxes to represent 18” of gravel under the roadway, 4” of screened gravel, 4” of binder, and 2” of topcoat. Boxes were also used to represent the curb, grass, and soil under the grass. It was hard to find a material to represent the asphalt for the topcoat. I selected the “fine stucco” material under the “surfaces” option, changed the base color to a dark gray, and the secular color to gray. I used global lighting, choosing the City of Boston. I also applied a “point light” to the bottom of the 18” of gravel. The combinations of these two lights created the effect of the afternoon, casting a shadow from the left side of the drawing to the right. Overall, I feel that this drawing did not come out as well as I hoped. I was disappointed that Microstation did not have very many options for surfaces related to highway construction. However, I was happy with the end results of the lighting effects. After completing this drawing, I do feel that I have a better grasp on how to use the 3-dimensional tools in Microstation.

I found the idea for my final project while I was estimating a project at work. It is a section of footer, foundation wall, slab, floor joists, sheeting, and a perforated continuous drainpipe surrounded by crushed stone. The first task that I found difficult was making the adjustment from x-y axes to x-y-z axes. I had trouble figuring out what dimension went in what order, and kept finding that the drawing looked correct in one view, but wrong in another. The second problem I faced was getting the lighting correct; it either appeared too bright or too dim. This was by far the hardest drawing skill-wise that I have ever accomplished, and I feel that it turned out extremely well.
