Divide faces into triangles or quadrangles

You can subdivide a polygon face into triangles or quadrangles using the Add Divisions feature (Edit Mesh > Add Divisions).

Note

You can also use Add Divisions to divide polygon edges. For more information see Divide polygon edges.

To divide a face using the Add Divisions feature

Select the faces you want to divide and choose Edit Mesh > Add Divisions > .
Set the Add divisions to either Exponentially or Linearly.
The Exponential setting subdivides the face or edge recursively. The Linear setting subdivides the face into an absolute number of segments. In addition, when Linearly is the selected Add Divisions setting, you can specify subdivisions in U and V.
Set the Division Levels to specify the number of subdivisions that occur for the selected faces depending on the Add divisions setting.
The Exponentially controls let you specify the Mode to be either triangles or quadrangles.
Click Add Divisions.

You can select the polySubdFace node and modify the subdivision settings in the Channel Box or Attribute Editor.

Troubleshooting the Add Divisions feature

A face does not subdivide: You cannot use the Add Divisions feature on faces that contain holes. Also, you cannot subdivide concave faces unless the center point is inside the face.

To subdivide a concave face into convex parts, use Edit Mesh > Split Polygon Tool or Mesh > Triangulate. To remove holes use Triangulate.
