{
    Alignment alignment = tr.GetObject(alignmentId, OpenMode.ForRead) as Alignment;
    ObjectIdCollection profileIds = alignment.GetProfileIds();
    
    if (profileIds.Count > 0)
    {
        Profile profile = tr.GetObject(profileIds[0], OpenMode.ForRead) as Profile;
        
        double station = 100.0;
