Nurbs are the most commonly used modelling tools in Cinema 4D. They are generators which create a surface from the use of other lines, curves or multiple objects.
The Extrude NURBS extrudes splines to give the object depth.
However, you might want to create a specific object that is not included in the predefined objects such as a heart.
By drawing only the profile of the an object, the Lathe NURB can generate a surface with a circumference by rotating the spline around the Y-axis. You usually use this when creating “round” objects such as glasses, bottles etc., which obviously cannot be found in the predefined splines.
This NURB requires at least two splines: the contour spline which will determine the cross section and the path which the contour spline will be generated on.
This NURB also requires at least two splines since it’s main purpose is to create a “coating” over the two or more splines as shown below.
This NURB, unlike the others, does not require any splines or other objects. It creates a single plane which you can then stretch and pull in all directions.This tool would be perfect to create sails on a ship.
It is important to mention that all the above NURBS can be further altered by using tools and options in the Attribute Manager.
