Associativity
Specifies that the new hatch pattern is updated when its boundaries are
modified.
A new hatch pattern's associativity is set by the HPASSOC system variable.
Changing the associativity setting here also changes the setting in the
HPASSOC system variable.
Do you want associativity? [Yes/No] <current>: Enter y or n , or press ENTER
Gap Tolerance
Sets the maximum size of gaps that can be ignored when objects are used as
a hatch boundary. The default value, 0, specifies that the objects must enclose
the area with no gaps.
Specify a boundary gap tolerance value <0>: Enter a value, in drawing units, from
0 to 5000
Any gaps equal to or smaller than the value you specify in the gap tolerance
are ignored, and the boundary is treated as closed.
Separate Hatches
Controls whether the command creates a single hatch object or multiple hatch
objects when several separate closed boundaries are specified.
Create separate hatches? [Yes/No] <current>: Enter y or n , or press ENTER
Draw Order
Assigns the draw order to a hatch or fill. You can place a hatch or fill behind
all other objects, in front of all other objects, behind the hatch boundary, or
in front of the hatch boundary. (HPDRAWORDER system variable)
Enter draw order [do Not assign/send to Back/bring to Front/send beHind
boundary/bring in front of bounDary] <send beHind boundary>: Enter an option,
or press ENTER to accept the default and return to the previous prompt
Origin
Controls the starting location of hatch pattern generation. Some hatches,
such as brick patterns, need to be aligned with a point on the hatch boundary.
By default, all hatch origins correspond to the current UCS origin.
[Use current origin/Set new origin/Default to boundary extents] <current>: Enter
an option, or press ENTER to accept the default and return to the previous prompt
Use current origin
Sets the value of the HPORIGINMODE system variable. The last 5 options
listed below correspond to the values 1-5.
