Network Pipe/Structure data fields

By Augusto Goncalves

Civil 3D has different ways to store custom data on different objects. On the specific case of Network Parts (Pipe or Structure), a user can store custom property values as described on this blog post. In this case, the information is stored under the Part.PartData property, that contains a list/array of PartDataField objects. An easy way to output this data is using the code below:

[CommandMethod("pipedatafield")]public static void CmdSelectPipe(){  Editor ed = Application.DocumentManager.MdiActiveDocument.Editor;  PromptEntityOptions peo = new PromptEntityOptions("nSelect network part: ");  peo.SetRejectMessage("nOnly network parts");  peo.AddAllowedClass(typeof(Part), false);  PromptEntityResult per = ed.GetEntity(peo);  if (per.Status != PromptStatus.OK) return;  ObjectId partId = per.ObjectId;   Database db = Application.DocumentManager.MdiActiveDocument.Database;  using (Transaction trans = db.TransactionManager.StartTransaction())  {    Part p = trans.GetObject(partId, OpenMode.ForRead) as Part;    PartDataField[] fields = p.PartData.GetAllDataFields();    foreach(PartDataField field in fields)    {      ed.WriteMessage("n{0}: {1}", field.Description, field.Value);    }  }}
