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)
With the Constrain property, you can specify that the Height, Turns, or Turn
Height properties of the helix are constrained. The Constrain property affects
how the helix changes when the Height, Turns, or Turn Height properties are
changed either through the Properties palette or through grip editing. The
table below shows the behavior of the helix depending on which property is
constrained.
