MASSPROP. Works good for both 2D and 3D Objects.
This will help you a lot if you want to know mass of any object for BOM Entry, Centroid of the object for Lifting, and other calculations, etc..
For both 2D and 3D, you can get Bounding Box, Centroid, Principal moments and X,Y,Z directions about centroid, Moment of Inertia, Products of Inertia, Radii of gyration.
And for 2D and 3D you can also get (area, Perimeter) & (Mass, Volume) respectively.
Just type MASSPROP and Select objects.
Use an object selection method to select either regions or 3D solids for analysis. If you select multiple regions, only those that are coplanar with the first selected region are accepted.
You can also save this data if you want to add these to a report, or keep them as a refence for future.
Specify whether you want to save the mass properties to a text file. By default, the text file uses a .mpr file extension.
