Point Markers and Labels
When you create points, you have the option to display point markers or
point labels, or both. Point markers can include point number, elevation,
and either raw or full description, and are controlled by settings on the Text
and Marker tabs in the Point Settings dialog box. If you want to label points
with additional data and insert description key symbols, you must use
point labels.
Point markers can stay the same size relative to the AutoCAD graphics
window, or they can be a fixed size in the drawing. The following illustration
shows point markers that are sized relative to the graphics window zoom
level.
Point markers include a point marker node and point marker text for point
number, description, and elevation. Although you must use labels to achieve
full description key substitution, you can substitute full descriptions for raw
descriptions using point markers.
In contrast, point labels can label any number of items. You can customize
point labels to display any type of information about points. You can label
points with data from external databases by using External Data References
(XDRefs). You can also set up point label styles that perform description key
substitution.

and Point Text Settings” on page 40. For more information about description
keys and point labels, see “Working with Description Keys” on page 53.
