This lab really helped me learn how I could use Rhino. When I first started using it I was really overwhelmed. There was so much to do that I didn't really know where to begin with learning how to use the program.
Part A:
This part was a really good place to start because it showed me how to create a shape.
Part B:
This was the part I was really worried about. I know that working with surfaces can be a little tricky and that they might not always do what I wanted them to do. This is still true after this exercise, but I definitely feel more comfortable with them. When creating curves, I had an idea for what something would look like, but then Rhino would have very different thoughts. I had the most fun with revolve and ended up using that a lot for part E.
Part C:
The thing that surprised me the most with this part is that there are so many ways to make a solid. The tools that I think were the most helpful were the Boolean tools. They were also the ones I enjoyed using the most. I also really liked Cage Edit which I thought was a really nice way to edit surfaces and solids. The ones I struggled with were FilletSrf and ChamferSrf. The video tutorials on Rhino helped a lot with this aspect of it. I
Part D:
I was so nervous about 3D printing an object. I just felt like I would mess it up or something, but it actually was really cool to see something digital and make it into a 3D form like that. I made a an evil cat looking thing for mine. This is where I found layers to be really helpful. For the previous parts it was a tedious thing I didn't like using them for that and eventually stopped using them all together. For these it was very helpful to make each separate object.
Here is the objects I used and me and the printer:
Part E: The part for which this post is named.
For this, I decided to do my piggy bank. Here are the photos I used and worked off of:
To make it:
-I used interpolate points to make curves that resembled the pig's shape.
-I used revolve for the main body. While it could have been done probably by just making a sphere and editing it, it was actually really nice using revolve because I was able to get that nose shape.
-For the ears, tail, and legs I made seperate objects and then joined them into the main object.
-For the Feet and the ears I used mirror and copy to place the same objects on the pig and then Cage edit to smooth out bends and bend in the ears slightly.
-For the top and bottom I used BooleanDifference to make impressions in the objects, I also did this for subtle indents for the nose.
