Area#
Functionality#
Area node is one of the analyzer type. It is used to get the area of any polygon or groups of polygons, no matter the number of its vertices or its world position.
Inputs#
Vertices and Polygons are needed. Both inputs need to be of the kind Vertices and Strings, respectively
Group by - indexes per faces. Used to group faces by numbers.
Parameters#
All parameters need to proceed from an external node.
Param |
Type |
Default |
Description |
|---|---|---|---|
Vertices |
Vertices |
None |
vertices of the polygons |
Polygons |
Strings |
None |
polygons referenced to vertices |
Summ Faces |
Boolean |
True |
output individual faces or the sum of all |
Outputs#
Area will be calculated only if both Vertices and Polygons inputs are linked. Group by - what group number for results areas if “Group by” used.

In the example we have the inputs from a plane with 16 faces. You can use Area node to get the sum of all of them or the area of every face individually.
Get Areas of Suzanne’s eyes#
Here you can calculate the area of objects individually
Get Areas with mesh join#
Summarize areas by materials over all objects
The “Mesh Join” and “Post” properties allow you to objectify not only materials that are polygonal Mesh, but also Metaball, Beveled/Extruded Bezier, NURBS surfaces.
Get Areas of Beveled Bezier and Nurbs#
You can use None material. In this case material will be None in the list.
