Large Assignment 1 – Andrei Phelps

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, FilletCorners

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

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.

Part 4: 3D Printed Model

I chose to print this model, scaling it up to 34.6 x 39.3 x 32.3 mm. However, Cura automatically added a cap to the top of the object. After troubleshooting in Rhino without finding the cause, I decided to modify the G-Code to pause at a specific layer number. It seems like I may have impacted the quality of the print towards the topmost layer, even though it appeared to be completely flat in the preview.
