Invalid Boundaries
When a boundary cannot be determined, it might be because the specified
internal point is not within a fully enclosed area. With the BOUNDARY
command, red circles are displayed around unconnected endpoints of the
boundary to identify gaps in the boundary.
The red circles remain displayed even after you exit the command. They are
removed when you specify a closed boundary, or by using REDRAW, REGEN,
or REGENALL.
Create Revision Clouds
Revision clouds are polylines that consist of sequential arcs. They are used to
call attention to parts of a drawing during the review stage.
