AssociativeHatch 属性（ActiveX）

2024-5-18 18:44| 发布者: admin| 查看: 329| 评论: 0|原作者: admin|来自: AutoCAD

指定填充是否具有关联性。

支持的平台：仅限 Windows

签名

VBA：

object.AssociativeHatch

对象

类型：舱口

此属性应用于的对象。

属性值

只读：是的

类型：布尔

True：填充是关联的。
False：填充不关联。

言论

当关联填充的边界被修改时，将更新其边界。修改非关联填充线的边界时，不会更新其边界。

只有在创建填充时才能设置关联性。有关创建填充的详细信息，请参阅该方法。AddHatch

例子

VBA：

Sub Example_AssociativeHatch()
    ' This example creates a hatch in model space.
    ' It then reports whether the hatch is associative.
    
    Dim hatchObj As AcadHatch
    Dim patternName As String
    Dim PatternType As Long
    Dim bAssociativity As Boolean
    
    ' Define the hatch
    patternName = "ANSI31"
    PatternType = 0
    bAssociativity = True
    
    ' Create the associative Hatch object
    Set hatchObj = ThisDrawing.ModelSpace.AddHatch(PatternType, patternName, bAssociativity)
    
    ' Create the outer loop for the hatch.
    ' An arc and a line are used to create a closed loop.
    
    Dim outerLoop(0 To 1) As AcadEntity
    Dim center(0 To 2) As Double
    Dim radius As Double
    Dim startAngle As Double
    Dim endAngle As Double
    center(0) = 5: center(1) = 3: center(2) = 0
    radius = 3
    startAngle = 0
    endAngle = 3.141592
    Set outerLoop(0) = ThisDrawing.ModelSpace.AddArc(center, radius, startAngle, endAngle)
    Set outerLoop(1) = ThisDrawing.ModelSpace.AddLine(outerLoop(0).startPoint, outerLoop(0).endPoint)
        
    ' Append the outer loop to the hatch object
    hatchObj.AppendOuterLoop (outerLoop)
    
    ' Evaluate and display the hatch
    hatchObj.Evaluate
    ThisDrawing.Regen True
    
    ' Return whether the hatch is associative.
    Dim hatchAssoc As Boolean
    hatchAssoc = hatchObj.AssociativeHatch
    MsgBox "The HatchStyle is " & IIf(hatchObj.AssociativeHatch, "associative.", "not associative."), , "AssociativeHatch Example"
    
End Sub
