If more than one person is working on the project and adding
points to the point database, then the points in your drawing may
not match the project points. You can update the drawing with the
project points by using the Modify Drawing command from the
Points
➤
Check Points menu. The following illustration shows the
options available when you use this command:

If you have points in a drawing that do not exist in the project, or
if you have used the ERASE command to erase points in a drawing,
then you can update the point database by using the Modify
Project command from the Points
➤
Check Points menu.
Locking and Unlocking Points
If you have control points such as benchmarks in a project, then
you may want to use the Lock Points command from the
Points
➤
Lock/Unlock Points menu to lock those points to
prevent them from being changed. For example, you may want to
lock points that were collected with a GPS (Global Positioning
System) receiver.
At a later time, if you discover that the datum elevation of the
survey was miscalculated, then you can unlock the points using the
Unlock Points command, edit the datum elevation, and then lock
the points again.
