我正在尝试使用 VBA 脚本连接 Autodesk Inventor 中的两个实体模型配置文件。我已经绘制了 3D 线条，这些线条应该在以后充当轮廓。脚本完成绘制后，我可以选择两个循环并通过 GUI 使用 loft 操作将它们连接起来。我认为这也应该可以从脚本中获得，我只是无法弄清楚如何。到目前为止，这是我的脚本：

Sub loft()

  Set oDoc = ThisApplication.Documents.Add(kPartDocumentObject, , True)
  Set oPartDef = oDoc.ComponentDefinition

  Dim osketch3D As Sketch3D
  Set osketch3D = oPartDef.Sketches3D.Add()

  Set oTG = ThisApplication.TransientGeometry
  Dim wire(198) As SketchLine3D

  Set wire(0) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(0, 0, 0), oTG.CreatePoint(10, 0, 0))
  Set wire(1) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(10, 0, 0), oTG.CreatePoint(10, 10, 1))
  Set wire(2) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(10, 10, 1), oTG.CreatePoint(0, 10, 0))
  Set wire(3) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(0, 10, 0), oTG.CreatePoint(0, 0, 0))

  Set wire(4) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(0, 0, 5), oTG.CreatePoint(10, 0, 5))
  Set wire(5) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(10, 0, 5), oTG.CreatePoint(10, 10, 5))
  Set wire(6) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(10, 10, 5), oTG.CreatePoint(0, 10, 5))
  Set wire(7) = osketch3D.SketchLines3D().AddByTwoPoints(oTG.CreatePoint(0, 10, 5), oTG.CreatePoint(0, 0, 5))

' .....    
' Select wires 0-3 and 4-7 as profiles, put them in an object collection and call the loft op.

End Sub
