Islands in AutoCAD are the objects inside the outer boundary of an area to
be hatched.
Click
Island detection
off if you do not want AutoCAD to recognize
the inner objects.
Click
Island detection
on if you want AutoCAD to select the inner
objects as boundaries and do not want to hatch them.
Select one of three styles:
Normal
: If three or more objects are nested inside each other, AutoCAD
will hatch the outer, leave the second, hatch the third, etc.
Outer
: If three or more objects are nested inside each other, AutoCAD
will only hatch the outer, leaving the inner objects intact.
Ignore
: If three or more objects are nested inside each other, AutoCAD
will ignore all the inner objects and only hatch the outer area.

Boundary Retention
By default, AutoCAD creates a polyline around the detected area. Once the
Hatch
command is fi nished, AutoCAD will delete this polyline.
The
Boundary retention
option allows you to keep this temporary
polyline.
°
Click the
Retain boundaries
checkbox and specify the
Object type
as
either
Polyline
or
Region
.
Boundary Set
When using the
Add: Pick points
option to defi ne the boundary to be
hatched, AutoCAD will analyze all of the objects in the
Current viewport
by default.
This could take a long time depending on the complexity of the drawing. To
minimize the time, you can provide a selection set for AutoCAD to analyze
the boundary.
