VBA填充多段线
您好，您能帮我在VBA上编写代码来填充多段线吗。例如：我有一条多段线，如下代码。如何对该多段线进行图案填充。谢谢
作为AcadLWPolyline的尺寸线
将点L1（0到9）设置为双精度
点L1（0）=0：点L1（1）=0
点L1（2）=0：点L1（3）=500
点L1（4）=75：点L1（5）=500
点L1（6）=75：点L1（7）=0
点L1（=0：点L1（9）=0
设置直线=此图形。模型空间。AddLightWeightPolyline（点L1）：直线。颜色=acRed 看来我找不到正确的方法
这是我最后一次尝试
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.18")
Set col2 = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.18")
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
ThisDrawing.Regen True
End Sub
当然，您必须使其适应多段线情况。这应该是最省力的，而为了获得图案/颜色等，可能需要更多的试验和测试工作。。你需要
