Part A:
In part A of this lab we needed to make curves using the various curve commands on Rhino, such as Sketch, HandleCurve, Curve, Polyline. The command I used the most was InterpCurve because I could make a shape very precisely and in any direction. We also needed to import a background bitmap, we could sketch any image. I chose a potted plant because there was straight lines as well as a few curves. I took a few of my shapes and used the split command to make a unique pattern that would later be printed and the shapes would be cut-out.
Part B
Instead of making 2-dimensional curves, in part B we were able to create
3-dimensional surfaces using multiple commands. The slideshow below shows all of the surfaces I created. The command I found the most useful was the ExtrudeCrv command because you could draw any 2 dimensional shape/base and extrude it so it would then become 3-dimensional. The commands I struggled with the most were Sweep1 and Sweep2.
Out of all the surfaces we modeled, we needed to pick two of them. The two images below are from my sketchbook. I sketched the front, side, and perspective of the two surfaces. In addition to this, we needed to modify the original surfaces and model them in Rhino. I decided to mirror, and scale down surface 1. I added a sphere to surface 2.
Part C
Part C was was similar to Part B in that we were given a list of multiple commands and we needed to model surfaces/solids using those commands. Below is a slideshow of all the surfaces I created. I enjoyed the boolean commands because they are very useful if you ever need to split, union etc.
Part D
In part D of this lab we got to print one of our models. I chose surfaces/solids from both part B and C. I changed them slightly by either combining or splitting surfaces. I used the boolean commands to make them watertight/closed form. The structure I chose to print was the one that resembled a cylinder because I liked the smoothness. The picture on the left shows all three of the solid shapes and the picture next to it is the new remodeled version of the shape I chose.
The three pictures below were taken at different stages during the printing process.

Part E
I really enjoyed part E because we modeled a real-life object in Rhino. I chose my glasses because I am very familiar with them and the shape is easily distinguishable. I started by taking numerous pictures at different angles (top, side, bottom) of my glasses. The commands I used when modeling my object were PictureFrame, Dim, InterpCrv, ExtrudeCrv, BooleanUnion, Mirror, Join. Below are pictures of the real-life object and the object I modeled at different angles.
