Week 5

Part 1

I created this stepped shaft by using revolve boss method. Later when I checked my mass on the quiz I realized the mass is incorrect, so I went in and check my model again. One of the dimension is placed over the wrong line and after I fix that the mass is correct.

Then I created the same model by extruding each of the cylinders, and then adding fillets.

Part 2

Using resolved boss to create a sphere from half a circle

Part 3

Using mirror to create a symmetrical shape and then revolve to form the V-grooved pulley. I added the fillets on the larger circle but I dint realize I had to add fillets on the smaller ones as well. When I added those fillets later the mass becomes correct. 

part 5

Adding holes onto the beam at 2 directions using linear pattern tool.

Part 6

Using a slot and 2 equal circles to create the blade, and then sketching one tooth and using linear pattern tool to create 300 copies of the tooth.

Part 7

Using loft feature to create this solid from a square and a circle at 2 parallel planes, then adding a hole using extruded cut.

Part 7

I started by sketching the path for the tube on the to plane. Adding horizontal relation to 3 points at the bending part makes the sketch fully defined. Next, I added circles on the front plane at the origin and then using Swept feature to create the bent tube.

Thoughts of the day: 

I had to do each step carefully and make sure my dimensions are correctly placed before making the sketch into 3D shapes to prevent the annoying and frustrating trouble shooting later on. Also, I realized it is important to understand the object so that you know what tools to use when sketching, and the overall process would be much more smoother.
