The Approach to the Cactus Model

SketchUp
1. Create section planes.
- For the “Cactus Model” in SketchUp, the distance between each plane that I will use is 2.4 meters. The reason is that the height of every element is greater than 2.4 meters, so they will appear on section planes. It should have approximately 33 section planes.
2. Observe each section plane from the top to bottom of the building and find the similarities and differences.
- If it has the same plane with other section planes, highlight the first and last noticing section planes. Therefore, it is not necessary to find dimensions on all 33 section planes.
3. Find dimensions.
4. Print out all necessary planes with the dimensions.
5. Find the height of each element.
- With each plane, observe the height of each element. In case there is the same height, connect those elements together. After that, write down the height above and below the plane.

SolidWorks
1. Set up planes.
2. Sketch the profile according to the dimensions gathered from SktechUp
3. Use ‘Extruded Cut’ to make a void.
- Put the height in both direction 1 (the height above the plane and) and direction 2 (the height below the plane).
4. Continue to work on each plane.
