Use this dialog box to select the point and block objects to use as centroids
for the polygons.
To create a polygon topology (page 836)
Click Create tab ➤ Topology panel ➤ New.
Each polygon in a polygon topology has a centroid, which is a point or block
element within the polygon, and contains information about the area it
encloses. Centroid information is stored as object data and saved with the
map. Each centroid is given a unique ID number, which is automatically
processed whenever you use a topology command.
You can select all point or block elements in the map or select them manually.
You can also filter (restrict) object selection to a subset of objects, in which
you include only the objects that are on specified layers, are of specified block
types, or in specified object classes.
Select All
Use all point or block objects that meet the filter criteria as centroids.
Select Manually
Include only the point or block objects that you manually select in the map.
Click Select Objects to select the objects. Only objects that meet the filter
criteria will be selected.
Layers
Specify the layers to use to filter (restrict) object selection to a subset of
objects, in which you include only the objects that are on the specified
layers. This filter is used for both automatic and manual selection of objects.
To select from a list of layers in the map, click Select Layers. To use all layers,
enter an asterisk (*) or leave the box blank.
Block Names
Specify the point or block objects to use to filter object selection. To use all
points and blocks, enter an asterisk (*) or leave the box blank. To select
from a list of block definitions in the drawing set, click Select Blocks. To
select point objects, select ACAD_POINT.
