Screw Modifier
The Screw modifier is similar to the Screw tool in the Toolbar, 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 properly aligned to the cardinal direction of the object rather than to the screw axis.
選項
The Screw modifier.
- 角度
Degrees for a single helix revolution.
- Screw
Offsets the revolution along its axis.
- Iterations
Number of revolutions.
- Axis
The axis along which the helix will be built.
- Screw
The height of one helix iteration.
- Axis Object
The name of an object to define the axis direction.
- Object Screw
Use the distance from the Axis Object to define the height of one helix iteration.
- Steps Viewport
Number of steps used for a single revolution displayed in the 3D Viewport.
- Render
As above, but used during render time. Increase to improve quality.
- Merge
Merge vertices that lie on the axis of rotation. Use this to close off end points with a triangle fan.
- Merge Distance
Vertices under this distance to the axis are merged.
- Stretch UVs
Stretch the UV coordinates from (0.0 to 1.0) when UVs are present.
Normals
- Smooth Shading
Output faces with smooth shading rather than flat shading. The smooth/flat shading of the input geometry is not preserved.
- Calculate Order
Order of edges is calculated to avoid problems with normals and shading. Only needed for meshes, not curves.
- Flip
Flip normals direction.
