Area Object area, storage type can vary 2D Grid,  Polyline Set, Point Set, Tri-mesh 1
ProjectionArea Area of the projection of a triangle onto a horizontal plane, storage type can vary. 2D Grid,  Polyline Set, Point Set, Tri-mesh  

Example 1 Area, storage type = per node

The Area variable returns area values for the selected object. Depending on the geometric representation of the selected object, the storage type can vary, e.g per node or per triangle. In the example below, the area of a tri-mesh is calculated, with storage type 'per node'. To calculate the area for that node, the following formula is used:

2 * (A * a/360 + B *b/360 + C * c/360 + D * d/360 + E * e/360)A,

Where A is the area of triangle A, B is the area of triangle B, etc. and a is the angle of triangle A at the location of the node, b is the angle of triangle B at the location of the node, etc.

Area. The area stored per node of a tri-mesh.    click to enlarge
