Hatch Pattern Definitions


Specification


Explanation


Angle


Defines the angle of the lines in the hatch pattern. If you also specify an angle in the Boundary Hatch dialog box, the two angles are added. For example, if ahatch pattern defines lines at 105 degrees and you specify a hatch angle of 30 degrees, you end up with lines running at 135 degrees.


X-origin


Specifies the X coordinate of the base point of the hatch pattern. Although your hatch probably won’t go through 0,0, AutoCAD uses this point to line up sets of lines in hatch patterns as well as to align hatch patterns in different areas. Because all hatch patterns are calculated from the base point, they are always aligned, no matter where they actually appear in the drawing.


Y-origin


Specifies the Y coordinate of the base point of the hatch pattern.


Delta-x


Specifies the offset of successive lines. This only applies to dashed lines and is measured along the direction of the lines. Specifying a delta-x staggers each successive line by the amount you specify so that the dashes do not line up.


Delta-y


Specifies the distance between lines, measured perpendicular to the direction of the lines. This applies to both continuous and dashed lines.


Dash


Defines a noncontinuous line using the same system as linetype definitions: positive for a dash, negative for a space, and zero for a dot.

The hatch pattern shown in Figure 31-6 is the simplest form of hatch pattern.
