Modify Helixes
You can use grips or the Properties Inspector 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 Inspector palette to change
the base radius independent of the top radius.
You can use the Properties Inspector 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 Inspector palette or through grip editing.
