Point Groups
Point groups
are another way of managing large amounts of point data. This
feature enables you to sort points based on a number of factors, such as descrip-
tion, elevation, point number, and manual selection. You can set up point groups
ahead of time so that points can be automatically sorted into groups as they are
imported into the drawing. You can also create new point groups on the fly to
sort points as you go.
Once points have been grouped, you can use them to study and manipulate
multiple points at once. The groups are listed in Prospector, and you can view the
points contained in each group simply by clicking the group name and viewing
the contents of the point group in the item view at the bottom (see Figure 3.5).
In addition, many point-editing commands allow you to select points by group,
enabling you to modify large numbers of points at once.

FiGuRE 3.5
The contents of a specific point
group shown in the item view of Prospector
Point groups also enable you to assign default point styles and label styles to
points within the group. With this capability, you can make points in a certain
group take on specific graphical characteristics by controlling the point style
and point label style.
