Splits selected polygon components (edges or faces) into smaller components. Add Divisions is useful when you need to add detail to an existing polygon mesh in either a global or localized manner.
Polygon faces can be divided into three-sided (triangles) or four-sided (quadrangles) faces. Edges can be subdivided so that the number of sides on a face is increased.
Settings
Determines how the selected faces or edges get subdivided into smaller components. The Division of the components can occur in either an exponential or linear manner depending on the component type.
Exponential Controls (for faces)
Specifies the number of divisions that occur for selected faces. The option can have a value ranging between one and four. The default value is one. A Division level of one divides a single face into four smaller faces when Exponentially is the selected Division method. If the Division level is set to two, a single face is subdivided into sixteen smaller faces.
Linear Controls (for edges)
When turned on, the specified Division value is the distance between vertices in world space. When turned off, the Divisions value is the distance between vertices in local space. This option is available for edges only.
