Question

我必须在两个部件之间移动一个像球体一样的探头，使探头与两个部件接触。我必须找到零件的接触点，测量它们的距离，并根据这个距离在零件上做一个圆角。我已经实现了在部件之间移动球体，但球体正在穿过部件。所以试图在约束条件下移动

我正在尝试自动化Catia产品中的操作工具。是否有任何命令或方法可以使用vba在Catia中移动关于约束的部分？

或

有没有办法用vba找到两个部分之间的冲突？

期待解决方案。

谢谢!!!

Here是一个链接，您可以在其中找到冲突的解决方案。

好的，我明白了，你想在这里看到代码： - ）

计算CATScript中的碰撞：

    Sub CATMain()

    ' get root product of document
    Dim RootProd As Product
    Set RootProd = CATIA.ActiveDocument.Product

    ' retrieve selection object of active document
    Dim objSelection As Selection
    Set objSelection = CATIA.ActiveDocument.Selection

    ' get two selected objects
    If (objSelection.Count2 <> 2) Then
    MsgBox "Before running the script you must select two products to compute clash for", vbOKOnly, "No products selected"
    Exit Sub
    End If

    Dim FirstProd As Product
    Dim SecondProd As Product

    Set FirstProd = objSelection.Item2(1).Value
    Set SecondProd = objSelection.Item2(2).Value

    ' create groups for clash computation
    Dim objGroups As Groups
    Set objGroups = RootProd.GetTechnologicalObject("Groups")

    Dim grpFirst As Group
    Dim grpSecond As Group

    Set grpFirst = objGroups.Add()
    Set grpSecond = objGroups.Add()

    ' add selected products to groups
    grpFirst.AddExplicit FirstProd
    grpSecond.AddExplicit SecondProd


    ' get access to Clashes collection
    Dim objClashes As Clashes
    Set objClashes = RootProd.GetTechnologicalObject("Clashes")

    ' create new clash
    Dim newClash As Clash
    Set newClash = objClashes.Add()

    ' set new clash to be computed between two groups (two selected products)
    newClash.FirstGroup = grpFirst
    newClash.SecondGroup = grpSecond

    newClash.ComputationType = catClashComputationTypeBetweenTwo

    ' compute clash
    newClash.Compute

    End Sub

是否有可能使用Catia vba移动一个部件而不是产品中的约束？
