A
point group has the following characteristics:

·        
It has persistent properties you can easily review or change.

·        
A points list displays the points included in a point group. The
point list can be updated automatically. This might be necessary when you
change the point group’s properties, create new points that match the point
group’s properties, or erase or modify points that match the point group’s
properties.

·        
A point group can be locked to prevent changes within a drawing.

Reasons to Use Point Groups

Point
groups provide a flexible and convenient way to identify points that share
common characteristics or that are used to perform a task, such as creating a
surface. You can use point groups to create groupings of points using point
number, point name, point elevation, raw (field) or full description, and other
characteristics.

Point
groups also play a fundamental role in controlling how a point displays in a
drawing. If you have a set of points that share common display characteristics,
you can use a point group to identify the point style and point label style for
all the points in the point group, instead of assigning a point style and a
point label style to each individual point. Also, using a point group you can
quickly change the style or label style for all the points in a point group at
once, instead of changing each point individually.

The
point group display order, the point group default styles, and the point group
override styles can all affect how a point is drawn.

Point Group Properties

A
point group is defined by properties which describe the criteria that a point
must match to belong to a point group, such as its point number, its name, its
raw or full description, or its elevation. Points that match the specified
criteria are added to the point group’s point list.

You
can create a point group either before or after you create the points that
belong to it. The point list is maintained dynamically, which means you are
notified whenever a change occurs that could affect the point list.

Note: A point can
belong to more than one point group.

 

You
create a point group by defining its properties.

Point
groups organize and identify points that share common characteristics. Use
point groups to assign point styles and point label styles for all the points
in a point group instead of assigning styles individually.

Important: The
highest point number allowed in Civil 3D is 4,294,967,295. You can use point
names or User Defined Properties to reference numbers greater than
4,294,967,295.

Use
the tabs on the Point Group Properties dialog box to define the
properties of a point group. The tabs you use depend on which method you use to
define a point group:

·        
The Basic Method. Use this method to easily define the
properties for many point groups. Use the Point Groups, Raw Desc
Matching, Include, and the Exclude tabs of the Point Group
Properties dialog box. Also, use this method when you want to identify
points that belong to a point group by selecting points in a drawing.

·        
The Query Builder Method. Use this advanced method to create
point groups by combining expressions, which allows you to use a single tab,
the Query Builder tab, to build a point group based on combinations
of point properties or point groups. When you create a point group using the
query builder method, the Point Groups, Raw Desc
Matching, Include, and Exclude tabs are not available.

To Create a Point Group Using
the Basic Method

 

 

1.   
Click Home tabCreate Ground Data panelPoints menuCreate Point Group.

2.   
In the Point Group
Properties dialog box, on the Information tab, enter a name, description, default styles, and a layer
for the point group.

3.   
To include points from
other point groups, click the Point Groups tab and select the check box next to any point group you
want to include.

4.   
To include points using
raw descriptions, click the Raw Desc Matching tab and select the check box next to the
raw descriptions you want to match.

All points in the drawing are searched, and
points with a raw description that matches a raw description specified on the
tab are included in the point group.

5.   
To specify criteria that
explicitly includes points in the point group, click the Includetab and define the criteria that a
point must match to be included in the point group.

6.   
To specify criteria that
explicitly excludes points from the point group, click the Exclude tab and define the criteria that a point must match to be
excluded from the point group.

7.   
To specify overrides for
points in the point group, click the Overrides tab.

8.   
To view the points in
the point group’s point list, click the Point List tab.
