Calculates the mass properties of selected 2D regions.
The following table shows the mass properties that are displayed for all regions.
| Mass properties for all regions | |
|---|---|
| Mass property | Description |
| Area | The surface area enclosed by the region. |
| Perimeter | The total length of the inside and outside loops of a region. |
| Bounding box | The coordinates of the two points that define the bounding box. For regions that are coplanar with the XY plane of the current user coordinate system, the bounding box is defined by the diagonally opposite corners of a rectangle that encloses the region. For regions that are not coplanar with the XY plane of the current UCS, the bounding box is defined by the diagonally opposite corners of an enclosing 3D box. |
| Centroid | The coordinate values of a point located at the geometric center. For regions that are coplanar with the XY plane of the current UCS, this is a 2D point. For regions that are not coplanar with the XY plane of the current UCS, this is a 3D point. |
If the regions are coplanar with the XY plane of the current UCS, the additional properties shown in the following table are displayed.
Enter massprop at the Command prompt.
The following prompts are displayed.

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.
