'StationOffsetElevationToXYZ' is ambiguous because multiple kinds of members with this name exist in class 'Autodesk.Civil.DatabaseServices.BaseBaseline'
This issue seems to be specific to VB.NET project (if you are using C# .NET, it works fine).
We have noticed this in Civil 3D 2014 release and by the time we address this issue in Civil 3D .NET API, here is a workaround with Reflection and .NET Extensions which you can adopt to overcome this -
Public Sub TestCommand()
Dim db As Database = Application.DocumentManager.MdiActiveDocument.Database
Dim civilDoc As CivilDocument = CivilApplication.ActiveDocument
If (civilDoc.CorridorCollection.Count = 0) Then Exit Sub
Using trans As Transaction = db.TransactionManager.StartOpenCloseTransaction
Dim corr As Corridor = trans.GetObject(civilDoc.CorridorCollection.Item(0), OpenMode.ForRead)
Dim bl As Baseline = corr.Baselines.Item(0)
Dim soe As Point3d = New Point3d(bl.StartStation, 0, 0)
Dim pointAtSOE As Point3d = bl.StationOffsetElevationToXYZ(soe)
End Using
End Sub
<<<
And declare a VB.NET Module as below:
>>>
Public Module Utility
<System.Runtime.CompilerServices.Extension()> _
Public Function StationOffsetElevationToXYZ(bl As Baseline, soe As Point3d) As Point3d
Dim args As Object = {CType(soe, Object)}
Dim argsModifiers As New System.Reflection.ParameterModifier(1)
' dont pass by reference, which is the new override for this method
argsModifiers(0) = False
Dim mods() As System.Reflection.ParameterModifier = {argsModifiers}
' Invoke the method late bound.
Return bl.GetType().InvokeMember("StationOffsetElevationToXYZ", _
System.Reflection.BindingFlags.InvokeMethod, _
Nothing, bl, args, mods, Nothing, Nothing)
End Function
End Module
