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
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, FilletCorner
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. BooleanIntersection

12. BooleanSplit

13. Using the surfaces and solids you modeled and the Boolean tools, make three solid shapes you find interesting.

Part 4: 3D Printing

I didn’t have too many issues when printing this piece. One thing I did struggle with was getting the proportions right so that I wouldn’t need supports. The overhang of this object was hard to get right but I ended up sliming the solid and making sure it does flare too far out from the center too quickly to avoid this overhang.
