InsertHatchByBoundary Method (ISketchManager)

Inserts a Hatch with the specified pattern, scale, angle, and boundary loop.

.NET Syntax

Visual Basic (Declaration) 
Function InsertHatchByBoundary( _
   const dsLongArray& BoundaryPointCountLongArray As System.Object, _
   const dsDoubleArray& BoundaryPointDblArray As System.Object, _
   const dsString& PatternName As System.String, _
   double PatternScale As System.Double, _
   double PatternAngle As System.Double _
) As Hatch
Hatch InsertHatchByBoundary( 
   System.object BoundaryPointCountLongArray,
   System.object BoundaryPointDblArray,
   System.string PatternName,
   System.double PatternScale,
   System.double PatternAngle
   BoundaryPointCountLongArray : Array,
   BoundaryPointDblArray : Array,
   PatternName : String,
   PatternScale : Number,
   PatternAngle : Number
) : dsHatch
COM native C++ 
HRESULT InsertHatchByBoundary( 
   VARIANT BoundaryPointCountLongArray,
   VARIANT BoundaryPointDblArray,
   BSTR PatternName,
   DOUBLE PatternScale,
   DOUBLE PatternAngle,
   IHatch** Hatch
DSRESULT InsertHatchByBoundary( 
   const dsLongArray& BoundaryPointCountLongArray,
   const dsDoubleArray& BoundaryPointDblArray,
   const dsString& PatternName,
   double PatternScale,
   double PatternAngle,
   dsHatch** Hatch



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


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


Name of the Hatch pattern


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


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



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.
