Lab 1: Part A
Description of what I did:
For part A of this lab I drew open and closed curves, practicing with the different function commands in Rhino. After making a few curves I changed their control points which dictated the curves' shapes and copied them or combined them together. I did this by clicking and dragging on the points as seen in step 7, and using more commands such as copy and join as seen in steps 9 and 10.
Lab 1: Part B
Description of what I did:
For part B of this lab I created 2 different surfaces using various commands (shown below) in Rhino. In order to create surfaces, I first had to create different curves, select them, and use different commands to create a surface from them such as Planarsrf, Edgesrf, Networksrf, and loft.
After modeling my surfaces, I chose 2 to draw in my sketchbook, and then sketched them with a modification in their shape. I then remodeled them in Rhino using some new curves and the loft command. Pictures of my sketches and final models are shown below:
Description of what I did:
For part C of this lab I created 2 versions of various solid objects using different commands (shown below) in Rhino. In order to use many of the commands I first created a surface using the fillet or Planarsrf commands. I then extruded that surface using the Extrudesrf command. With the created solid I then used the various commands: MoveFace, MoveEdge, FilletEdge, Cap, and OffSetsrf. For testing the boolean commands I used the box, cylinder, and sphere commands.
Lab 1: Part D
Description of what I did:
For part D of this lab I created 3 solid shapes by taking some of the surfaces and solids that I modeled in parts B and C of this lab, and combined them or cut into them using the boolean commands BooleanDifference, BooleanSplit, and BooleanUnion. These 3 solids are shown below:
I then chose the furthest solid on the right to 3D print on the Ender 3 printer. I thought about how the holes in the shape could be used to fit over shafts of a larger creation or object. It could possibly slide along a shaft or fit onto an object with nubs fitting into its rectangular holes. The solid seemed similar to a knob, so I redesigned it to fit over a value slider as a custom knob. The redesign is shown below on the left, and original object on the right:
