Code Examples

Example 1: Listing Structure Properties

using (Transaction tr = civilDoc.Database.TransactionManager.StartTransaction())
{
    Network network = tr.GetObject(networkId, OpenMode.ForRead) as Network;
    ObjectIdCollection structureIds = network.GetStructureIds();
    
    foreach (ObjectId structId in structureIds)
    {
        Structure structure = tr.GetObject(structId, OpenMode.ForRead) as Structure;
        
        ed.WriteMessage($"\nStructure: {structure.Name}");
        ed.WriteMessage($"\n  Location: ({structure.Location.X:F2}, {structure.Location.Y:F2})");
        ed.WriteMessage($"\n  Rim Elevation: {structure.RimElevation:F2}");
        ed.WriteMessage($"\n  Sump Elevation: {structure.SumpElevation:F2}");
        ed.WriteMessage($"\n  Connected Pipes: {structure.ConnectedPipesCount}");
    }
    
    tr.Commit();
