Exercise 2: 3D Curves

Instructions:
The Rhino file posted below has three pipe objects, each on a separate layer. Download this file and open it to begin this exercise. The challenge is to draw a 3D curve for each pipe that approximates the “curve to pipe around” for each pipe. Each pipe’s layer is named to indicate the exact number of control points that must be used for their respective curves. The curves you draw must have the correct number of control points and must fit completely inside of their respective pipes. Create a new layer for each curve and name it to clearly associate with the corresponding pipe/number of points.

Here is the Rhino file.
