有没有办法通过宏在 Catia 中创建公式来链接参数？

  • 772

在此处输入图片描述主要目的是使用宏在 Catia 中通过公式链接两个参数。我尝试手动记录该过程，但代码没有给出完整的代码：

Sub CATMain()
Dim partDocument1 As partDocument
Set partDocument1 = CATIA.ActiveDocument
Dim part1 As part
Set part1 = partDocument1.part
Dim parameters1 As Parameters
Set parameters1 = part1.Parameters
Dim parameterSet1 As ParameterSet
Set parameterSet1 = parameters1.RootParameterSet
Dim parameterSets1 As ParameterSets
Set parameterSets1 = parameterSet1.ParameterSets
Dim parameterSet2 As ParameterSet
Set parameterSet2 = parameterSets1.GetItem("Construction_Position")
Dim parameterSets2 As ParameterSets
Set parameterSets2 = parameterSet2.ParameterSets
Dim parameterSet3 As ParameterSet
Set parameterSet3 = parameterSets2.GetItem("R_Point") ' Cannot print the method call put_Value for the object RealParam
Dim relations1 As Relations
Set relations1 = part1.Relations
Set parameterSet3 = parameterSets2.GetItem("R_Point")
Dim formula1 As Formula
Set formula1 = relations1.CreateFormula("Formula.2", "", ' Cannot print the method call CreateFormula for the object Relations
part1.Update
End Sub

我从这个过程“手动”得到的最终公式是

formula.2: Construction_Position\R_Point\R_Point_X=Construction_Position\H_Point\H_Point_X

有人能帮我吗？我试过 CHATGPT，但根本不起作用

  1. 我不是 Catia 专家，但我浏览过http://catiadoc.free.fr/online/interfaces/interface_Relations.htm#CreateFormula 并尝试了以下步骤：

    Sub CATMain()
    Dim partDocument1 As PartDocument
    Dim part1 As Part
    Dim relations1 As Relations
    Dim formula1 As Formula
    Dim parameters1 As Parameters
    Dim paramHPointX As Parameter
    Dim paramRPointX As Parameter

    Set partDocument1 = CATIA.ActiveDocument
    Set part1 = partDocument1.Part
    Set parameters1 = part1.Parameters
    Set relations1 = part1.Relations
    Set paramHPointX = parameters1.Item("Construction_Position\H_Point\H_Point_X")
    Set paramRPointX = parameters1.Item("Construction_Position\R_Point\R_Point_X")

    'formula linkin
    ' Formula syntax: "iName", "iComment", "Formula"
    Set formula1 = relations1.CreateFormula("Formula.4", "", paramRPointX.Name & " = " & paramHPointX.Name)
    part1.Update
End Sub

    CreateFormula需要将公式管理的参数作为第三个输入，将公式作为字符串作为第四个参数。获取公式中使用的参数的“名称”的最佳方法是使用函数GetNameToUseInRelation。此外，您的代码缺少访问一个参数集级别。下面是此类代码的示例

    Sub CATMain()

Dim oPart As Part
Dim oRelations As Relations
Dim oParameters As Parameters
Dim parameterSet_H As ParameterSet
Dim parameterSet_R As ParameterSet
Dim parameterSet_Construction As ParameterSet
Dim oParameter_H as Parameter
Dim oParameter_R as Parameter
Dim oFormula As Formula

Set oPart = CATIA.ActiveDocument.Part
Set oRelations = oPart.Relations
Set oParameters = oPart.Parameters

'get Parametersets
Set parameterSet_Construction = oParameters.RootParameterSet.ParameterSets.Item("Construction_Position")
Set parameterSet_H = parameterSet_Construction.ParameterSets.Item("H_Point")
Set parameterSet_R = parameterSet_Construction.ParameterSets.Item("R_Point")

'get Parameters
Set oParameter_H = parameterSet_H.DirectParameters.Item("H_Point_X")
Set oParameter_R = parameterSet_R.DirectParameters.Item("R_Point_X")

'create formula
Set oFormula = oRelations.CreateFormula("","", oParameter_R, oParameters.GetNameToUseInRelation(oParameter_H))

oPart.Update

End Sub
