catia二次开发 VBA语言

有朋友能帮忙解答一下倒数第三行出现了什么问题吗,一直报错😭

Dim reference1 As Reference
Dim iSelection
Set iSelection = CATIA.ActiveDocument.Selection

Dim iStatus, iType(0)

'选择Geometrical set部件集

iType(0) = "HybridBody"

iStatus = iSelection.SelectElement2(iType, "Please select the Geometrical Set", False)

If iStatus = "Redo" Or iStatus = "Undo" Or iStatus = "Cancel" Then

Exit Sub

End If

Rem Set reference1 = originElements1.PlaneYZ

Set reference1 = iSelection.Item(0).Value

Dim sketch1 As Sketch
Set sketch1 = sketches1.Add(reference1

根据你提供的代码,倒数第三行出现了问题。具体地说,代码中的 sketches1 变量没有被定义,因此代码无法执行该行。

你需要确保在使用该变量之前,已经定义了 sketches1 变量,或者你需要根据你的代码来判断是否有任何其他问题导致 sketches1 变量未被正确定义。

参考代码:

vbnet
Copy code
Dim reference1 As Reference
Dim iSelection As Selection
Set iSelection = CATIA.ActiveDocument.Selection

Dim iStatus As Integer, iType(0) As String

' 选择Geometrical set部件集
iType(0) = "HybridBody"
iStatus = iSelection.SelectElement2(iType, "Please select the Geometrical Set", False)

If iStatus = "Redo" Or iStatus = "Undo" Or iStatus = "Cancel" Then
    Exit Sub
End If

Set reference1 = iSelection.Item(1).Value
Dim sketches1 As Sketches
Set sketches1 = reference1.Parent.Parent.Sketches

Dim sketch1 As Sketch
Set sketch1 = sketches1.Add(reference1)
代码中,主要做了以下更改:

将 iSelection 声明为 Selection 类型,以避免后面的类型错误。
将 iType 的定义从 Dim iType() As String 改为 Dim iType(0) As String,以避免后面的类型错误。
将 iSelection.Item(0).Value 改为 iSelection.Item(1).Value,因为 Item 的索引从 1 开始,而不是 0。
添加了对 sketches1 的定义和初始化。
将 sketches1.Add(originElements1.PlaneYZ) 改为 sketches1.Add(reference1),以便将 reference1 作为草图的参考平面。
