所以我想知道我能不能在这里得到一些帮助。所以基本上我试图找出如何编写一个能够将样条线导入Catia的dat文件。这些样条曲线在导入时应该像结构上的网格一样，即画出一个网格结构，但是它不是网格，而是在它上面使用样条曲线。所以现在我想学习一个宏，它将我在结构上创建的一些样条线导出到文本（.dat）文件中。但我一直遇到麻烦我有它，因为它要求我选择一个样条曲线，但不允许我点击spec树中的样条曲线。事情是，我有很多样条曲线，我希望宏只是自动选择样条线而不要求并导出它们..... PLS帮助我。非常感谢。
所以这是代码：

StartKrit = 1
End If
If StartKrit = 0 Then
box = MsgBox(" The active document is neither a CATPart still CATDrawing! " + Chr(10) + _
" The macro can not continue and will now exit " + Chr(10) + _

您的selectelement2过滤器是否为spline2D设置，您选择了草图样条线还是三维样条线？
如果您正在使用类似听起来的三维样条线，则需要使用此代码：
mysel.Clear
otype3D(0) = "HybridShapeSpline"
mysel.Clear
box = MsgBox("Please select now the spline", vbInformation + vbOKCancel, "spline Select")
If box = vbCancel Then
box = MsgBox("you have canceled the selection" + Chr(10) + _
"The macro is now finished!", vbCritical, "abort by user")
If fs.FileExists(StorePath & StoreName & ".txt") = True Then
A.Close
fs.DeleteFile (StorePath & StoreName & ".txt ")
End If
Exit Sub
End If
Selection = mysel.SelectElement2(otype3D, " Please select the spline ", False)
