Detailed Description

Combined OCCT mass-property value computed for a graph node.

linear_length is the total curve length of edges in the shape, surface_area is the total face area, and volume is the signed solid volume. mass uses unit density and follows the highest non-zero dimensional property: volume, then area, then length. The inertia matrix is row-major, about centre_of_mass, in the global XYZ frame.
