helix or spiral
helix curve can be used as a path or a guide for swept features, or guide curve for lofted feature.
To create a helical or spiral:
Click Helix and Spiral Curves on the toolbar, or click Insert, Curve, Helix / Spiral.
Open the sketch and sketch a circle. This controls the diameter of a circle diameter of the helix (except in thevariable pitch helixes).
Helix / Spiral PropertyManager arise when we create a new helical or spiral in a sketch or edit a helix or spiral.
Set the value that should be included in the Helix / Spiral PropertyManager.
Pitch and Revolution.
Make a helix defined by Pitch and Revolutions.
High and Revolution.
Make a helix defined by the High and Revolutions.
Height and Pitch.
Make a helix defined by the height and pitch.
Spiral.
Make a spiral is determined by the pitch and Revolutions.
Constant Pitch.
Create a constant pitch along the helix.
Variable Pitch.
Making a pitch varies based on regional parameters that we specify.
Region Parameters (Variable pitches only).
Set the revolution (Rev) or high (H), diameter (Dia), and level pitch (P) for the variable pitch helix.
Pitch.
Set the rate of change of radius for each revolution.
Revolutions.
Set the number of rounds.
Reverse direction. create a spiral inward.
Start angle.
Set where to begin sketching a circle
Clockwise.
Setting the direction changed to clockwise.
Counterclockwise.
Set the turn into the opposite direction.
Click OK.
