Helix/Spiral PropertyManager
The Helix/Spiral PropertyManager
appears when you create a new helix or spiral
in a sketch or edit an existing helix or spiral. The PropertyManager controls
the following properties:
Defined By
Pitch and Revolution. Creates a helix defined by Pitch
and Revolutions.
Height and Revolution.
Creates a helix defined by Height
and Revolutions.
Height and Pitch.
Creates a helix defined by Height
and Pitch.
Parameters
Constant
Pitch. Creates a constant pitch throughout the helix.
Variable
Pitch. Creates a varied pitch based
on the Region Parameters you
specify.
Region
Parameters (Variable pitches only).
Sets the revolutions (Rev) or
heights (H), diameters (Dia), and pitch rate (P)
for a variable pitch helix.
Height
(Helix only). Sets the height.
Pitch.
Sets the rate of change of radius for each revolution.
Revolutions.
Sets the number of turns.
Reverse direction.
Extends the helix backwards from the point of origin, or creates an inward
spiral.
Start angle.
Sets where to start the first turn on the sketched circle.
Clockwise.
Sets the direction of the turns to clockwise.
Counterclockwise.
Sets the direction of the turns to counterclockwise.
Taper Helix
Taper Helix. Creates a tapered helix.
Taper Angle 
. Sets the angle of the taper.
Taper outward.
Tapers the helix outward.
