Dynamic Curves:

1. Create a new file

2. Create a curve:

   • Any way you like will work
   • A curve that has more points will be preferable
   • You will want some curviness to your curve

3. Make the curve dynamic:

   • Select the curve
   • Dynamics Menu Set > Hair > Make Selected Curve Dynamic
   • You will now have two curves; one that's dynamic and one that's static. Playing through your animation will quickly show the difference between the two.

4. Make the curve a solid:

   • Place a cylinder at the shared base of the two curves
   • Select the faces of one of the ends
   • Polygon Menu Set > Edit Mesh > Extrude Faces Options. The number of divisions depends on how smooth you want the strand. Forty-two is a good number.
   • Make sure "use selected curve for extrusion" is checked.
   • Extrude

5. Tweak Settings:

   • You may find that your "thread" is a little rubbery. You should tweak the settings of the "thread" by changing the attributes of the hair system that was generated.
   • Experiment with stiffness
   • Experiment with length-flex

6. Wash, Rinse, Repeat:

   • Make a second string in the same file, using the above method.
   • When you get to the section titled "Wash, Rinse, Repeat", do not recurse! This would be an infinite loop.
   • Change something noticeable in the new curve's settings. (i.e. put different forces on it in the Hair System Shape attributes)
   • Change the follicle shape to allow one end to hang free. Do this by changing the follicle shape's "point lock" attribute to either base or tip.

7. Render!
