Modifying 2D Spirals and 3D Helixes

Use EntityGrips or the Properties palette to modify 2D spirals and 3D helixes.

1. Use EntityGrips to modify the following properties:
   • Axis position
   • Start point
   • Base radius
   • Top radius
   • Height
   • Direction in Z axis
2. Use the Properties palette to modify other properties, such as:
   • Twist direction
   • Number of revolutions
   • Pitch
3. You can also select a Constraint. This dimension remains constant when you create or modify helixes. For example:
   • Pitch. The pitch value is constant. As the height changes, the number of revolutions is calculated.
   • Revolutions. The number of revolutions is constant. As the height changes, the distance between revolutions is calculated.
   • Height. As the height changes with the EntityGrip, the number of revolutions is unchanged and the distance between revolutions is calculated.
