Answer:
In this case, there is an error in EXCEL VBA that cannot be fixed from our side. For this reason, a new object, RFEM.RfLine (instead of RFEM.Line) has been created, which you can use to continue your work. Here is a brief example:
Sub test_RfLine() Dim iModel As RFEM5.IModel2 Set iModel = GetObject(, "RFEM5.Model") iModel.GetApplication.LockLicense
On Error GoTo e Dim iModelData As RFEM5.IModelData2 Set iModelData = iModel.GetModelData Dim lines() As RFEM5.RfLine lines = iModelData.GetLines e: If Err.Number <> 0 Then MsgBox Err.Description, , Err.Source Set iModelData = Nothing iModel.GetApplication.UnlockLicense Set iModel = Nothing End Sub
