Face Area Node

Face Area Node.

The Face Area node outputs the surface area of a meshs faces. The units are in Blender units no matter the unit system, equivalent to meters-squared at the default unit scale.

Note

For quads and N-gons, when the faces vertices are not planar, the output is not necessarily the same as the sum of every one of the faces triangles visible in the viewport. In this case it should only be used an approximation. In some cases, the Triangulate can be used to get an exact value.

Inputs

Properties

Outputs

Area

The surface area of each of the meshs faces.

Combined with the Attribute statistic, this node can be used to calculate the total surface area of a mesh.
