|
|
|
|
The *Face Area* node outputs the surface area of a mesh's faces.
|
|
The units are in Blender units no matter the unit system,
|
|
equivalent to meters-squared at the default unit scale.
|
|
|
|
.. note::
|
|
|
|
For :term:`quads <Quad>` and :term:`N-gons <N-gon>`, when the face's vertices are not planar,
|
|
the output is not necessarily the same as the sum of every one of the face's triangles visible
|
|
in the viewport. In this case it should only be used an approximation. In some cases,
|
|
the :doc:`/modeling/geometry_nodes/mesh/operations/triangulate` can be used to get an exact value.

Combined with the :doc:`/modeling/geometry_nodes/attribute/attribute_statistic`,
|
|
this node can be used to calculate the total surface area of a mesh.
