Screw Modifier

Mode: Any mode

Panel: Modifiers

Description

The Screw modifier is similar to the Screw tool in the Tool Shelf in that it takes a profile object, a Mesh or a Curve, to create a helix-like shape.

Properly aligning the profile object is important

The profile should be two dimensional and properly aligned to the cardinal direction of the object rather than to the screw axis.

Options

Screw modifier
Axis
The axis along which the helix will be built.
Screw
The height of one helix iteration.
AxisOb
The name of an object to define the axis direction.
Object Screw
Use the Axis Object to define the value of Screw.
Angle
Degrees for a single helix revolution.
Steps
Number of steps used for a single revolution (displayed in the 3D view.)
Render Steps
As above, used during render time. Increase to improve quality.
Calc Order
Order of edges is calculated to avoid problems with normals. Only needed for meshes, not curves.
Flip
Flip normals direction.
Iterations
Number of revolutions.
