Modifying Helixes

You can use grips or the Properties palette to modify the shape and size of a helix.

You can use the grips on a helix to change the following properties:

• Start point
• Base radius
• Top radius
• Height
• Location

When you use a grip to change the base radius of a helix, the top radius scales to maintain the current ratio. Use the Properties palette to change the base radius independent of the top radius.

You can use the Properties palette to change other helix properties, such as

• Number of turns (Turns)
• Turn height
• Direction of the twist — clockwise (CW) or counterclockwise (CCW)
