Now change the pattern to<br />

*SKEWED<br />

0, 0,0, .5,.5, .5,-.5<br />

It is the same, except that you have set delta-x to 0.5. This offsets each<br />

successive family member by 0.5 in the direction of the line (in this case,<br />

parallel to the X axis). Because the lines are infinite, the dash pattern slides<br />

down the specified amount. The hatched area would look like this:<br />

To create a hatch pattern with dashed lines<br />

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

format (for example, Notepad).<br />

2 Create a header line that includes an asterisk and a pattern name. The<br />

name of the hatch pattern is limited to 31 characters.<br />

3 (Optional) To include a description in the header line, follow the pattern<br />

name with a comma and description text.<br />

4 Create a descriptor line that includes<br />

■ An angle at which the line is drawn<br />

■ An X,Y origin point<br />

■ A delta-x of any value if you want to offset alternating lines in the<br />

line family<br />

■ A delta-y of any value<br />

■ A value for a dash length<br />

■ A value for a dot length<br />

■ An optional second value for a different dash length<br />

■ An optional second value for a different dot length<br />
