Create a Pipe Network, unable to add parts

Jeff_M — Mon, 06 Sep 2021 15:02:58 GMT

I am attempting to get or create a pipe network and add some pipes to it. If the Network has already been created in C3D everything works as expected. However, if the Network does not exist and I create it in code, no parts can be added to it, in code or even manually in C3D. Comparing the code created Network with one created in C3D I see zero differences in the properties.

I have a few Extension methods I use to get the existing Networks and to create the Network if needed. It all works up until I try to add a part to a created Network. Any ideas on how to get this to function properly? I currently will be forcing the user to create a Network in C3D prior to running the tool.

///<summary> ///Returns Dictionary of ObjectIds & names of all pipe networks in the document. ///</summary> public static Dictionary<ObjectId, string> GetPipeNetworkNames(this CivilDocument civDoc) { Dictionary<ObjectId, string> dict = new Dictionary<ObjectId, string>(); using (Transaction tr = HostApplicationServices.WorkingDatabase.TransactionManager.StartTransaction()) { foreach (ObjectId objId in civDoc.GetPipeNetworkIds()) { Network net = (Network)objId.GetObject(OpenMode.ForRead); dict.Add(objId, net.Name); } tr.Commit(); } return dict; } public static ObjectId GetOrCreatePipeNetwork(this CivilDocument civDoc, string name) { ObjectId retval = ObjectId.Null; foreach (var pair in civDoc.GetPipeNetworkNames()) { if (pair.Value == name) { retval = pair.Key; return retval; } } retval = Network.Create(civDoc, ref name); return retval; } //and this is a snip where I get/create the Network var ntwrkId = civdoc.GetOrCreatePipeNetwork("Test"); var ntwrk = (Network)ntwrkId.GetObject(OpenMode.ForWrite); //make sure the Network has a PartsList assigned try { var tmp = ntwrk.PartsListId; } catch { ntwrk.PartsListId = civdoc.Styles.PartsListSet[0]; }

I should add that I have tried wrapping the creation in a separate Transaction to insure the Network is database resident prior to adding the parts.

I was unable to reproduce your problem. I took your code and used it to create a new network with 1 structure in it and it worked. I tried it in one of the built in templates, as well as my own template. The code worked in the following versions of Civil 3D:

2019.3.1

2020.6
2021.3
2022.0

Below is the code I used to create the network and structure. I copied your extension methods into an extension class so the code would be the same as yours (as much as possible).

using (Transaction tr = Self.Db.TransactionManager.StartTransaction()) { // Create the network var ntwrkId = Self.CivDoc.GetOrCreatePipeNetwork("Test"); // Self is just a static class I use to store convenient references to the Editor, CivilDocument, Database, etc. Self.CivDoc is the current CivilDocuement var ntwrk = (Network)ntwrkId.GetObject(OpenMode.ForWrite); // Make sure the Network has a PartsList assigned try { var tmp = ntwrk.PartsListId; } catch { ntwrk.PartsListId = Self.CivDoc.Styles.PartsListSet[0]; } // Create a structure at 0,0,0 var psc = PartSizeContainer.GetPartSizeContainers(ntwrk.PartsListName, DomainType.Structure)[0]; //GetPartSizeContainers is a helper function for getting a list of all the part sizes in a partslist ObjectId newStId = ObjectId.Null; ntwrk.AddStructure(psc.FamilyId, psc.PartSizeId, Point3d.Origin, 0, ref newStId, false); var st = (Structure)newStId.GetObject(OpenMode.ForWrite); tr.Commit(); }

Note that in the above code I made comments for 2 functions (GetPartSizeContainers and Self.CivDoc), which are just some helper classes/methods that I use and should not affect anything.

I do not know why it would not be working for you, I can only guess at a possible drawing corruption or maybe the parts list does not properly match the pipe catalog set.

@Kyle-L thanks for checking this. I had tested in 2 different drawings (using C3D 2020) before posting. I'm fairly certain that the same partslist I was using is the same as the one used to manually create a network, but I will have to go back and verify that. It's good to know that I should be able to get this to work.

@Kyle-L, thanks again! Sure enough, the PartList I used in both drawings I tested was the culprit.

@Jeff_M I am glad you found the cause!

Hi,

Good solution,
Having the same issue (c3d 2022) with my dynamo script/creation, and I want to use your solution.
How do you use this note into the dynamo script? or other?

thanks

Have you tried to use nodes toolkit

Care to elaborate more? I haven't face with this situation in the past, but I afraid I will. So it would be good if we can know more details about this..

A partslist refers to various parts in your pipe catalog, it basically tells C3D which parts to use from your catalog.

If you have a partslist in your drawing that refers to a pipe catalog other than the one that you have set then when you try to create a pipe the partslist fails to find the pipe in the set catalog thus the pipe is not created.
