How I Designed This

This (5,3) ribbon torus knot was designed entirely in Cinema4D. The curve was created using the Formula tool with parametrization x=(2+cos(5t))cos(3t), y=(2+cos(5t))sin(3t), z=-sin(5t) from t=-pi to t=pi. The trianglulated surface was created by first adding in a small rectangle, then using the SweepNurbs (without caps). The rectangle was also rotated 1800 degrees in the process. The small gap was fixed using the Bridge tool in Edge mode.
