Using Additional Hatch Features

Using Additional Hatch Features
AutoCAD’s Boundary Hatch command has a fair amount of “intelligence.” As you saw in an earlier
exercise, it was able to detect not only the outline of the floor area, but also the outline of the toilet
seat that represents an island in the pattern area. If you prefer, you can control how AutoCAD treats
these island conditions and other situations by selecting options available when you click the More
Options button in the lower-right corner of the Hatch And Gradient dialog box.



This button expands the dialog box to show additional hatch options.


Islands
The Islands group at the top of the dialog box controls how nested boundaries affect the hatch pattern.
The graphics in this group show examples of the effect of the selected option. The Islands
options include the following:
Island Detection Turns on the Island Detection feature. This check box excludes closed objects
within the boundary from being hatched. For example, when you were hatching the bathroom in
an earlier exercise, the toilet seat wasn’t hatched, because it was an island within the boundary.
Normal Causes the hatch pattern to alternate between nested boundaries. The outer boundary
is hatched; if there is a closed object within the boundary, it isn’t hatched. If another closed object is
inside the first closed object, that object is hatched. This is the default setting.
Outer Applies the hatch pattern to an area defined by the outermost boundary and a closed
object within that boundary. Any boundaries nested in that closed object are ignored.
Ignore Supplies the hatch pattern to the entire area within the outermost boundary, ignoring
any nested boundaries.
