Analyze Mass Properties > Area Moments |
The AreaMoments command reports the area moments of inertia and corresponding axes of surfaces, polysurfaces, meshes, or closed planar curves with respect to the world coordinate system.

- The area moments of inertia compute on the entire collection of objects. For example, if you select a box polysurface, the area moments will compute using all six sides of the box.
- To analyze the area moments of a surface that is part of the polysurface, either extract the surface from the polysurface using the ExtractSrf command or use the sub-object selection when selecting the surface.
- For mass properties analysis, it is frequently convenient to model a real-world solid, like a boat hull made from thin steel plate with a surface or open polysurface. The AreaMoments command can estimate the volume moments of this shell without having to actually create the boat hull as a complete thin-walled solid.
-
Cumulative area moments are calculated from all objects in a group unless using Command+Shift+click to select group members separately.
- Group members that are hidden or on hidden layers will not be calculated.
