This function helps you label a coordinate position in your drawing.
Keyboard Command: DrwLabCrd
Simply choose the point you wish to identify (using osnaps if necessary), then pick a second point to form a leader. If the second point chosen was to the right of the first, the label will be left justified at the end of the leader. If the second point was to the left of the first, the label will be right justified. The coordinates are labeled with a N/E prefix at the current LUPREC precision.
There are two modes of labeling in this tool. The primary is Cartesian coordinates, which will be used almost all of the time. However, if the current drawing coordinate system is decimal latitude/longitude, you can label the coordinates in degrees/minutes/seconds. To access this option press M for Mode, then enter LL for the lat/long mode.
