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.
