2024-5-18 19:08| 发布者: admin| 查看: 173| 评论: 0|原作者: admin|来自: AutoCAD

指定填充线的类型，经典或渐变。

支持的平台：仅限 Windows

签名

VBA：

object.HatchObjectType

对象

类型：舱口

此属性应用于的对象。

属性值

只读：不

类型：枚举AcHatchObjectType

acHatchObject
acGradientObject

言论

此属性的默认值为 0，，这将创建一个经典的填充线。acHatchObject

如果此属性的值为 1，，则通过创建填充线的方法创建渐变。如果创建了渐变，则应且应包含梯度图案名称 LINEAR、CYLINDER、INVCYLINDER、SPHERICAL、HEMISPHERICAL、CURVED、INVSPHERICAL、INVHEMISPHERICAL 或 INVCURVED。acGradientObjectAddHatchPatternTypeAcGradientPatternTypePatternName

例子

VBA：

Sub Example_HatchObjectType()
    ' This example changes the value of the HatchObjectType property.
    ' The example requires that the active drawing contain an existing hatch.
    
    AppActivate ThisDrawing.Application.Caption
    
    Dim ent As AcadHatch
    Dim util As AcadUtility
    Set util = ThisDrawing.Utility
    Dim pt As Variant
    Call util.GetEntity(ent, pt, "Select hatch :")
    With ent
        MsgBox "Initial value of HatchObjectType = " & .HatchObjectType
        .HatchObjectType = acGradientObject
        .GradientAngle = 3.1415 / 4
        .GradientCentered = False
        .GradientName = "SPHERICAL"
        Dim col1 As AcadAcCmColor, col2 As AcadAcCmColor
        Set col1 = .GradientColor1
        Set col2 = .GradientColor2
        col1.SetRGB 255, 0, 0
        col2.SetRGB 0, 255, 0
        .GradientColor1 = col1
        .GradientColor2 = col2
        MsgBox "New value of HatchObjectType = " & .HatchObjectType
    End With
End Sub
