On April 15th, I received a new assignment Experiment 2/3 in course des 100. This assignment is completely different from the previous assignment. This time we will challenge using Rhino to intersect 2 or 3 at a non-vertical angle. Three-dimensional geometric primitives (such as cuboid, cone, cylinder, etc.) to create virtual objects.

I couldn't figure out anything at first, I just knew how to stack two models together, but what I wanted was how to make it change. So I feel like I learned how to manage my time from my last assignment. And make good use of your own thinking and plan what you want to do before doing it. This time I almost made the same mistake as last time, but fortunately I found it in time and I will start drawing my plan until I am satisfied, and then I will make a model.

Record: On April 22nd, I have been drawing my plan, but today Fiona said that I need to make the first model. I will catch up as soon as possible and need to select a graphic to make an interactive model. Try to make two handmade models by next week.

I used and planned three different model geometries for testing. 

1. Cylinder Square 

2. Geometry of Squares and Triangles 

3. Square cylinder geometry. 

From the last lesson, I learned to start directly from the final. Later, I only need to know how to stitch it together more easily to determine my final model. The next step is to learn how to make flat unfolded drawings, and then start working by hand. The model I chose was the first cylindrical cube because I thought this model would be particularly interesting to make and I thought they were very average and looked great.

Today I tried my model for the first time, and I used the expansion diagram on rhino to do this. I found that after the completion of this model and the model I made did not fully meet my expectations. I found that I had miscalculated and had no Angle. This was my first small model that gave me a little bit of difficulty and challenge. I found that I needed to learn more about rhino next time. And I found that when I pieced it together, it didn't fit the assignment.Tomorrow I will try a new model, I will try to open and use the correct way to put the cube into the cylinder. 

This is my second attempt, and I found it very difficult because this cylinder is very easy to roll because it's easy to make with paper, but this cylinder is very difficult to roll with cardstock and it gets a little damaged and creased.

After Fiona and Hans' suggestions and careful instruction, I chose to use sticks to make the cylinder more round. Then we studied it by using the example in module. I realized that I needed to calculate it and I used pie times distance to figure out the circumference of the circle so I reprinted it to make it perfect and rounder.

Next time I'll need to compute the model early rather than doing it directly in rhino with bad balance and bad proportions.
