P3D line number list show and show selected linenumber pipeline only

I am a new user of P3D, when i design pipelines, sometimes there are so many pipes and fittings, thus ,I want to display and isotlate some pipelines,however,I have two problems need help：

1) I want to show the line numbers of all pipelines including supports contained in the ModelSpace, how can I get them ?

2) If I want to display only the objects of Specified line numbers ,others be hidden, which method can I use?

Thans very much for your reading.

There are several ways to approach this. One is to iterate all Plant 3D model items, retrieve their property values, check if they match your criteria, set them as the implied selection set, and then run a command on the set (such as ISOLATE, HIDEOBJECTS, etc.).

The method works well but wtih a deficiency that for project has lots of piping, the speed is slow, can the line number list show in the Piping UI be get by program code ,it it can, that will be very good.

I tried to useAutodesk.ProcessPower.P3dUI.UIsetting AllPipingLineNumbers Method ,

however i faiiled,is there any suggestion about it?

In your original post you asked for pipe groups in Model Space - the UI dropdown shows all line groups for the entire project. You can get all project line groups by iterating the P3dLineGroup table in the database - similar example here. If you want the linegroups for the current model only, the most reliable way is by the retrieving model space items' property. You can try to use the relationship method but I've found it to return inaccurate results:

Editor ed = AcadApp.DocumentManager.MdiActiveDocument.Editor; Database db = doc.Database; PlantProject currProj = PlantApp.CurrentProject; PipingProject pipeProj = (PipingProject)currProj.ProjectParts["Piping"]; DataLinksManager dlm = pipeProj.DataLinksManager; // get linegroups related to current drawing int dwgId = dlm.GetDrawingId(db); if (dwgId != -1) { PnPRowIdArray relatedLgIds = dlm.GetRelatedRowIds("P3dDrawingLineGroupRelationship", "Drawing", dwgId, "LineGroup"); foreach (var relatedLgId in relatedLgIds) { PnPRow lgRow = dlm.GetPnPDatabase().GetRow(relatedLgId); ed.WriteMessage($"\nrelated lineGroup: {lgRow["Tag"].ToString()}"); } }
