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, InterCurve, HandleCurve, Sketch
     
5. Import a picture and trace an image
   • Commands: Picture, InterCurve
     
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 4: 3D Printing

I chose the image below as my 3D print. I chose the model due to its curves and sharp angles. I wanted to see how sharp my 3D printer could get on the polygon shapes and how smooth the curves edges could get. I had a lot of issues with adhesion either due to the model or the type of filament I was using. The edges of the print kept getting rolled and sometimes the structure wouldn’t hold. I tried different settings on my printer and changed the layer height to get a detailed print. Changing the layer height really helped with the curves due to their angle. The print reminds me of a puzzle and its curious to see if the cut outs would slide in. Plus I think it would be a good way to see the tolerance of the machine.
