Create Helix-Spiral |
Model > 3D Power Pack |
The Create Helix-Spiral command creates a helix-shaped or spiral-shaped 3D object from one or more path objects. The paths can be 2D objects or NURBS curves.
To create a helix or spiral:
Select the object to use as the path.
Select the command.
The Helix-Spiral Creation dialog box opens; specify the object parameters.

Parameter |
Description |
Use Turns |
Creates a helix/spiral by a specified number of turns along the path |
Turns |
Enter the total number of turns to be created along the path |
Use Pitch |
Creates a helix/spiral by pitch |
Pitch |
Enter the pitch value (the distance between successive turns) |
Start Radius |
Enter the radius of the perpendicular starting circle |
End Radius |
Enter the radius of the perpendicular ending circle. To create a helix, enter a value matching the start radius. To create a spiral, enter a different value. |
Start Angle |
Enter the starting point of the twist on the starting circle |
Reverse Direction |
Changes the rotation direction of the helix/spiral from clockwise to counter-clockwise or vice versa |
Flatten |
Flattens the helix/spiral into a 2D spiral. Use Pitch is not available with this option.
|
A helix or spiral is created.
A helix or spiral object can be used, without further conversion, as a path object for the Extrude Along Path command.
Ungrouping a helix-spiral object results in a NURBS curve.
