Define hatch sub-patterns
Sub-patterns are the basic elements that comprise the total hatch pattern. They are simple patterns of individually defined lines, which together form the whole pattern. The appearance of each line is determined by a number of settings, such as color and line type.
The sub-patterns of existing hatching can be changed. The procedure for defining sub-patterns is similar for both new and existing hatch patterns. In the Sub Pattern dialog box, you specify the following attributes:
 Color Sets the color of the simple pattern. Line Type Sets the line type of the simple pattern. Distance Determines the repetition width of the simple pattern within the whole pattern. The repetition width is calculated as: repetition width = distance x distance of the hatch. You can enter any positive value for the distance. Offset Determines the starting point of the simple pattern within the whole pattern. The starting point is calculated as: starting point = offset x distance of the hatch. You can enter any value between 0 and less than 1 for the offset. Angle Determines the drawing angle of the simple pattern. The drawing angle is calculated as: drawing angle = angle + angle of the hatch.
To create a new sub-pattern,
1. Click Annotation and then, in the Annotate group, click the arrow next to Properties.
2. Click Hatch. The Modify Hatch dialog box opens.
3. Click the Subpattern button in the general section. The Edit Subpattern dialog box opens.
4. Click Insert in the Edit Subpattern dialog box. The dialog box displays a new sub-pattern with default attributes (a solid white line with distance 1 and offset and angle values of 0).
5. Enter the desired changes.
6. Click to complete the operation.
Note that the new sub-pattern is inserted after the current one. To delete the current sub-pattern, click Delete in the Edit Subpattern dialog box.
The number of the current sub-pattern and the total number of existing sub-patterns is shown as a fraction in the menu. Click the right or left arrows, when applicable, to move forward or backward among the sub-patterns.
