How to pattern linear and circular at the same time?

Tutorial by sumithkarun

This type of pattern could be solved creating a 3D curve (Helix) and patterning datum point on the curve,as I have explained below

  1. Step 1:

    1- Create a sphere of dia 10mm and put a datum point on the center

  2. Step 2:

    2- Create an assembly , and create a curve using equation
    x=200*t
    y=50*sin(6*t*360)
    z=50*cos(6*t*360)

    For a helix with a r=50 and a height of 200

    The radius and height varies upon your need

  3. Step 3:

    3- Create a datum point on the curve (length ratio =0) , this is the point where you mate/assemble the part

  4. Step 4:

    4-Pattern the datum point , using dimension pattern . The no of items depends upon designers descretion, I have choosen 21 items at 0.05 length ratio increment.

  5. Step 5:

    5-Assemble the sphere coinciding the point together

  6. Step 6:

    6-Select the part and click the pattern icon, automatically Creo goes for reference pattern .
