This command locks points in the coordinate file so that their
names, coordinates and descriptions cannot be modified. There are
several types of coordinate files. Lock points only works with the
CRDB format because this format in an SQLite database which has a
point attribute for lock status. To check on the format of the
current coordinate file, run Coordinate File Utilities (CFU) which
shows the format type at the top of the dialog. To change the
current coordinate file format to CRDB, run CFU and choose the
Convert CRD File Format function.
The only way to modify locked points is to first run the Unlock
Points command and then run one of the point edit
functions.
The points to lock can be selected by point number range, point group, inclusion/exclusion perimeter polyline areas, or screen selection. There is a dialog to choose the method and specify a description match filter.
