What is the difference between an
extrusion and a revolve?
Extrusion and revolve are both methods used in 3D modeling to create solid objects.
Extrusion is the process of stretching and forming a 2D shape along a linear path in order to create a 3D object. This is commonly used to create shapes such as boxes, cylinders, and tubes. The original 2D shape remains the same but is extended in the Z-axis direction to create a 3D object.
Revolve, on the other hand, is the process of revolving a 2D shape around an axis to create a 3D object. This is commonly used to create objects with rotational symmetry, such as cones, spheres, and wine glasses. The original 2D shape is rotated around an axis to create a solid object with rotational symmetry.
In summary, the main difference between extrusion and revolve is the way in which the 3D object is formed: extrusion stretches a 2D shape along a linear path, while revolve rotates a 2D shape around an axis.
