- To enable point-locking, click the
Point lock
button on the status bar. The button changes to a shut lock
.
- To disable point-locking, click the
Point lock
button again. The button changes to an open lock
.
To enter a position that is not on the principal plane, you can:

- Type the coordinates.
If you snap to a key point that does not lie on the principal plane (as shown below):
then the new position is projected onto the principal plane:
When you move the intelligent cursor over such a key point, it changes to show that clicking the key point will project new positions onto the principal plane.
