  1. Step 1:

    Go to respectively; Start> Shape> Generative Shape Design.

  2. Step 2:

    Click “Point” and set coordinates as X= 0, Y= 50, Z= 0. Press “OK”.

    Click “Point” one more time and set coordinates X=0, Y=-25, Z=0. Press “OK”.

  4. Step 4:

    Select “Line Definition” for selected point and select “Create Point” on coordinates (0, 0, 0). Select line type as “Point- Direction” and pick direction as Z component. Set start distance as 12 mm.

  5. Step 5:

    Select (0, 50, 0) coordinated point and go to “Circular Pattern Definition”, set parameters “Complete Crown”; instances will be “5” and “Z Axis” will be the reference element.

  6. Step 6:

    Select (0, -25, 0) coordinated point and go to “Circular Pattern Definiton”, set parameters as “Instances and angular spacing”, instances: 5, angular spacing: 72 deg and reference element will be “Z Axis”, press “OK”.

  7. Step 7:

    Go to “Line Definition” and select parameters respectively as shown below.

  8. Step 8:
