[求助]怎样创建填充图形

xia_jxs

各位大侠 ：

  在ATUOLISP中用(command "solid" in_pk31 in_pk30 in_pk32 in_pk31 \)命令可以创建一个

三角填充图。

VBA中怎样实现此功能？

我用下面的命令，系统提示输入点无效

ThisDrawing.SendCommand "solid" & vbCr & "pick_point_first(0)" & vbCr & "point_arrow(0)" & vbCr & "point_arrow(1)" & vbCr & "pick_point_first(0)" & vbCr

谢谢各位大侠帮忙

CAD帮助文件中有这样的代码，稍做修改便可以满足要求：

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
   
  
    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.16")
    Set col2 = AcadApplication.GetInterfaceObject("AutoCAD.AcCmColor.16")
    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) 换成三角就可以了
    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
