Controls the settings for the 3D object snaps.
| Type: | Integer |
| Saved in: | Registry |
| Initial value: | 11 |
Controls which 3D object snaps are enabled. The setting is stored as a bitcode using the sum of the following values:
| Value | Description | Shortcut Keys |
| 1 | Disables all 3D object snaps | ZNON |
| 2 | Snaps to a vertex or a control vertex | ZVER |
| 4 | Snaps to the midpoint on a face edge | ZMID |
| 8 | Snaps to the center of a face | ZCEN |
| 16 | Snaps to a spline or surface knot | ZKNO |
| 32 | Snaps to a perpendicular face (planar faces only) | ZPER |
| 64 | Snaps to an object nearest to a face | ZNEA |
| 128 | Snaps to closest point in point cloud, without segmentation data. | PNOD |
| 256 | Snaps to nearest point on planar segment of point cloud. | PNEA |
| 512 | Snaps perpendicular to a planar segment on point cloud. | PPER |
To specify more than one object snap, enter the sum or their values. For example, entering 6 specifies the vertex (2) and midpoint (4) object snaps.
