.5,.5 for the first instance of the pattern, so its origin is at this point. The third
line of the pattern could be the following:

90, .5,0,0,1,.5,-.5

or

270,.5,1,0,1,-.5,.5

The dashed pattern starts at the origin points and continues in the vector
direction given by the angle specification. Therefore, two dashed-line families
that are opposed 180 degrees are not alike. Two solid-line families are alike.

The following pattern creates six-pointed stars.

This example can help you refine your skills at pattern definition. (Hint: 0.866
is the sine of 60 degrees.)

The following is the AutoCAD LT definition of this pattern:

*STARS,Starof David

0, 0,0,0,.866,.5,-.5

60, 0,0,0,.866,.5,-.5

120,.25,.433,0,.866,.5,-.5

To create a hatch pattern with multiple lines

1 Open the acadlt.pat or acadltiso.pat file in a text editor that saves in ASCII

format (for example, Notepad).

2 Create a header line that includes an asterisk and a pattern name. The

name of the hatch pattern is limited to 31 characters.

3 (Optional) To include a description in the header line, follow the pattern

name with a comma and description text.

4 Create a descriptor line that includes

■ An angle at which the line is drawn

■ An X,Y origin point

■ A delta-x of any value if you want to offset alternating lines in the line

family
