Surfaces > Primitives > Cylinder

Creates a NURBS cylinder (tube), with an option for capping the ends with extra trimmed surfaces.

Procedures

Create a 3D geometric primitive

Cylinder Options

Object Degree

The degree of the curves or surfaces used to create the object. Choose 1 (linear) or 3 (cubic).

Sweep

The degrees of rotation around the center of radial primitives.

For example, if you enter 180 degrees in the sphere tool, Alias creates a hemisphere.

Sections

The number of subdivisions (spans) on the surface.

The default is 8. At least 4 subdivisions are usually needed to create a workable primitive shape. It is not usually necessary to use more than 20 subdivisions.

Caps

Creates trimmed surfaces to close the ends of the cylinder. Choose 0 (no caps), 1 (a cap at one end), or 2 (caps at both ends).
