class ON_HatchLine /////////////////////////////////////////////////////////////// Represents one line of a hatch pattern Similar to AutoCAD's .pat file definition ON_HatchLine's are used by ON_HatchPattern to specify the dashes and offset patterns of the lines.
Each line has the following information: Angle is the direction of the line CCW from the x axis The first line origin is at base Each line repetition is offset by offset from the previous line offset.x is parallel to the line and offset.y is perpendicular to the line The base and offset values are rotated by the line's angle to produce a location in the hatch pattern's coordinate system There can be gaps and dashes specified for drawing the line
If there are no dashes, the line is solid Negative length dashes are gaps Positive length dashes are drawn as line segments
