Large Assignment 1: Desiree Forster

Part 1: Curves

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
   • 
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
   • 
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.
14. Add a link to your FirstnameLastname_Solids file at this point in your post.

Part 4: 3D Printing

I chose to print a vase-like structure with a star-shaped opening. The object itself was created using the Circle, Copy, Scale 2D, Polygon-Star, PlanarSrf, and Loft commands. As for the print process, my object was scaled to about 82x76x119 mm in Cura, with 10% infill density and a grid infill pattern, and took about 4 hours and 21 minutes to print. Surprisingly, the only problem I experienced was at the very beginning of my print. The leveling wasn’t quite right which kept the filament from sticking as it was extruding. Fortunately, it was something I caught early on and only required a quick re-leveling to fix.
