创建图案填充对象。 支持的平台:仅窗口 签名工 务 局: RetVal = object.AddHatch(PatternType, PatternName, Associativity [, HatchObjectType])
言论创建对象后,必须使用方法添加外部循环。必须关闭外部循环,并且必须先创建外部循环,然后才能创建任何内部循环。内部循环是使用该方法一次创建一个的。HatchAppendOuterLoopAppendInnerLoop 注意:创建对象后,必须将外部循环追加到对象,才能使其成为有效的 AutoCAD 对象。如果尝试调用方法以外的任何操作,AutoCAD 将进入不可预知的状态。HatchHatchAppendOuterLoop
例子工 务 局: Sub Example_AddHatch()
' This example creates an associative gradient hatch in model space.
Dim hatchObj As AcadHatch
Dim patternName As String
Dim PatternType As Long
Dim bAssociativity As Boolean
' Define the hatch
patternName = "CYLINDER"
PatternType = acPreDefinedGradient '0
bAssociativity = True
' Create the associative Hatch object in model space
Set hatchObj = ThisDrawing.ModelSpace.AddHatch(PatternType, patternName, bAssociativity, acGradientObject)
Dim col1 As AcadAcCmColor, col2 As AcadAcCmColor
Set col1 = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor." & Left(AcadApplication.Version, 2))
Set col2 = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor." & Left(AcadApplication.Version, 2))
Call col1.SetRGB(255, 0, 0)
Call col2.SetRGB(0, 255, 0)
hatchObj.GradientColor1 = col1
hatchObj.GradientColor2 = col2
' Create the outer boundary for the hatch (a circle)
Dim outerLoop(0 To 0) As AcadEntity
Dim center(0 To 2) As Double
Dim radius As Double
center(0) = 3: center(1) = 3: center(2) = 0
radius = 1
Set outerLoop(0) = ThisDrawing.ModelSpace.AddCircle(center, radius)
' Append the outerboundary to the hatch object, and display the hatch
hatchObj.AppendOuterLoop outerLoop
hatchObj.Evaluate
