| Since it is possible to accidentally drag points, selected vertices can be "locked" to prevent them from being dragged or edited (using the [[WMS:Properties Window|Edit Window]]) by selecting the '''Vertices | Lock/Unlock''' command from the '''TIN''' menu. Any number of combinations of vertices can be locked or unlocked.

| Locking and unlocking vertices provides a differentiation between points that are hard (measured data) and points that may be soft (interpolated or estimated data).

| | |
| Selected vertices can be unlocked by selecting the '''Vertices | Lock/Unlock''' command from the '''TIN''' menu. The status of each vertex, locked or unlocked, is preserved in the TIN file when TINs are saved to disk. Display options can be changed so that a distinction between unlocked and locked vertices is easily visible.
