Exercise 10.3

Modeling a Building Component (Part 2)


There are two primary ways to use the power of 3D computer modeling software to produce architectural models. In this exercise, you will explore “modeling through layers of details.” For this exercise, you will be modeling a structural glass wall (complete with steel hardware).

Part 1:

  1. Begin by drawing the shape to the below. You will likely need to use the Polyline tool (Rhino Tutorial 5.5) as well as the Arc tool. Pay careful attention to measurements.
  2. Next, use the Rotate3D command (Rhino Tutorial 5.6) to rotate the shape up into the vertical direction.
  3. Use the join command (Edit>Join) to join all of your lines together
  4. Now, use the circle tool to draw a circle at the end point of the object.
  5. Use the Sweep 1 Rail command (Rhino Tutorial 5.10) to create a tubular surface that defines the steel rod used in the spider clamp.
  6. Next, use the circle tool to define the 1.5” buttons at the base of the steel rod created in step 5. Refer to drawing on the back of this page.
  7. Use the Surface>Extrude Curve>Straight command to create the surface of the button. Make sure to change the Cap to “Yes.” The button should be 0.5” thick. Repeat for the opposite side of the steel rod.
  8. Use the Copy/Move commands to make a copy of your piece. Use the rotate command to rotate it 90 degrees from the first one (to make an “X”). You now have the base of your steel spider.
  9. Next, using the methods discussed above, create the tension rod that extends from the steel spider to hold the 3/8” diameter tension cable. Refer to the dimensions on the back of this sheet if necessary. (This should test your understanding, which is why I’m not writing a step by step guide.)
  10. Now, at point (0,0) create a 4’ x 6’ x 1/2” thick piece of glass (rectangular surface)
  11. Move your finished spider from above to rest on top of the piece of glass as indicated in the plan on the back of this sheet. Add the 3/8” steel cable to the height of the glass.
  12. Once you have the final piece assembled, use the Rotate3D command to change the whole unit so that it rests in the vertical plane.
  13. Now, use either the Render command or the Print command to create a .jpg of your window assembly. Please post this .jpg to the course website.
  14. Note: With any remaining time, continue to work on trimming (Rhino Tutorial 5.9) your concrete walkway (we will use both the walkway and the glass on Monday).
