Helical Wave Shape Spring & Spherical Helix by Datum Curve.

Helical Wave Shape Spring

Step A:

  1. Create a new part.
  2. Create a datum curve >> curve from equation
  3. Select Cylindrical Coordinates Variable used- r, theta & z
  4. Click on equation >> add equation in note pad window – r=5 theta=t*3600 z=(sin(3.5*theta-90))+24*t
  5. Verify the equation.

Spherical Helix by Datum Curve

Step B

  1. Create a new part.
  2. Create a datum curve >> curve from equation
  3. Select Spherical Coordinates Variable used- rho, theta & phi
  4. Click on equation >> add equation in note pad window – rho=4 theta=t*180 phi=t*360*20
  5. Verify the equation
