Parameters

BoundaryPointCountLongArray

Array containing a long that is the number of points in the Hatch boundary loop

BoundaryPointDblArray

Array of x-y coordinates of the points in the Hatch boundary loop

PatternName

Name of the Hatch pattern

PatternScale

Value by which to scale the Hatch pattern; values are between .25 and 2 in .25 unit increments; default is 1 (see Remarks)

PatternAngle

Angle of the Hatch pattern lines; values are between 0 and 2*pi radians in .26 radian increments; a positive angle rotates the pattern counter-clockwise

Hatch[out] or Return Value

Hatch

If PatternScale is equal to:

• 2.00, then the distance between pattern lines doubles. 
• 0.25, then the distance between pattern lines is 1/4 the original distance.

PatternScale is valid only when the HatchPatternType parameter of IHatchPattern::GetHatchOrSolidData is not dsHatchPatternType_e.dsHatchPatternType_UserDefined.

To scale user-defined Hatch patterns, call IHatchPattern::SetHatchOrSolidData to change the line spacing of the Hatch pattern.
