Part 1: Curves

Open a new Rhino File and practice the curves commands by completing the following steps. Organize your Rhino file so each step is clear. Use the Text command to label each step and the commands you used.

1. Make the specific footprint below.
   • Commands: Polyline
     
     
2. Make 2 closed rounded curves using the various curve commands.
   • Commands: Curve, InterpCurve, HandleCurve
     
     
3. Make 2 closed curves using polygon, ellipse, or circle
   • Commands: Circle, Ellipse, Polygon
     
     
4. Make 2 open curves
   • Commands: Curve, InterpCurve, HandleCurve, Sketch
     
     
5. Import a picture and trace an image
   • Commands: Picture, InterpCurve
     
     
     I wanted to include the center of the sunflower as well as the outline, so there’s 2 InterpCurves there. The InterpCurves and text are green due to being in Layer 4.
6. Pick one open curve, and one closed rounded curve and make three copies of each.
   • Commands: Copy
     
     
7. Take at least 3 of your closed curves and overlap them to create a new shape
   • Commands: Move
     
     
     I rotated the ellipse slightly here in order to line it up better with the other shapes.
8. Use split, delete, and trim to combine these curves into one open curve
   • Commands: Split, Delete, Trim, Join, Explode
     
     
9. Take at least two curves and use various transformations make a pattern or composition.
   • Commands: Move, Copy, Rotate, Mirror, Array, Scale, Offset, Fillet, FilletCorners
     
     
10. Organize your Rhino file so each step is clear. Use the Text command to label each step and the commands you used. Add a link to your FirstnameLastname_Curves file at this point in your post.

Part 2: Surfaces

Open a new Rhino File and practice the surfaces commands below by making two different surfaces for each command. Organize your Rhino file so each step is clear. You may want to use some of the curves you modeled in Part 1. Use the Text command to label each step and the commands you used.

1. Plane
   
   
2. PlanarSrf
   
   
3. EdgeSrf
   
   
4. ExtrudeCrv
   
   
5. ExtrudeCrvAlongCrv
   
   
6. Loft
   
   
7. Sweep1
   
   
8. Sweep2
   
   
9. Revolve
   
   
10. RailRevolve
    
    
11. Add a link to your FirstnameLastname_Surfaces file at this point in your post.

Part 3: Solids

Open a new Rhino File and practice the solids commands below by making two different solids for each command. You may want to use some of the curves and surfaces you modeled in Parts 1 and 2. Organize your Rhino file so each step is clear. Use the Text command to label each step and the commands you used.

1. Box
   
   
2. Cylinder
   
   
3. Sphere
   
   
4. ExtrudeCrv and Cap
   
   
5. Pipe
   
   
6. MoveFace
   
   
7. MoveEdge
   
   
8. OffsetSrf
   
   
9. BooleanUnion
   
   
10. BooleanDifference
    
    
11. Boolean Intersection
    
    
12. BooleanSplit
    
    
13. Using the surfaces and solids you modeled and the Boolean tools, make three solid shapes you find interesting.
    
    

    

    All 3 solids were created using preexisting geometry, except for some boxes I added to the 3rd one to make it printable. The 1st one was created with BooleanUnion and BooleanDifference. The other 2 used only BooleanUnion.
14. Add a link to your FirstnameLastname_Solids file at this point in your post.

Part 4: 3D Printing

Initially I ran into some problems, though not with the design of my print. I assumed my bed would still be leveled after I leveled it for the first print. It was not, so I’m going to have to buy a new surface plate. Once I successfully re-leveled, I ran into no other issues.
