Shapes and Splines
Spline
A shape is an object made up of one or more splines. A spline is a collection
of vertices and connecting segments that form a line or curve. By adjusting
values in the vertices, you can make portions of the line curved or straight.
Shapes don't usually appear in the rendered scene. They're used for the
following purposes:
■ As the foundation for extruded objects, by applying an Extrude modifier
to the shape.
■ As the foundation for a spun object, by applying a Lathe modifier to a
shape.
■ As the components that make up a Loft object, by combining a shape as
a path, and one or more shapes as cross-sections along the path.
■ As an animation path for an object by assigning a path constraint to the
object, and then picking a shape as the path.
