Mimic Line Number > New feature on Plant 3D

<?xml encoding=”UTF-8″>By Augusto Goncalves

This post is actually inspired on create a new line group previous post, but with some changes. This will actually mimic the Line Number >> New >> Assign Tag feature on Plant 3D.

First, remove previous group related to the pipe, in order to avoid belong to more than one line group, which can be a modeling error. Second, just make the code simpler to include on your code. Note this will run for individual pipe making each pipe into a different line group (therefore different ISO production from each of them), you may adjust to a group of pipes.

<span>private</span> <span>static</span> <span>void</span> CreateNewTag(<span>ObjectId</span> partId, <span>string</span> newTagValue)<br>{<br>  <span>PlantProject</span> currentProj = <span>PlantApplication</span>.CurrentProject;<br>  <span>PipingProject</span> pipeProj = (<span>PipingProject</span>)currentProj.ProjectParts[<span>"Piping"</span>];<br>  <span>DataLinksManager</span> dlm = pipeProj.DataLinksManager;<br>  <span>PnPDatabase</span> db = dlm.GetPnPDatabase();<br> <br>  <span>PnPTable</span> p3dLineGroupTable = db.Tables[<span>"P3dLineGroup"</span>];<br>  <span>PnPRow</span> lgRow = p3dLineGroupTable.NewRow();<br>  lgRow[<span>"Tag"</span>] = newTagValue;<br>  p3dLineGroupTable.Rows.Add(lgRow);<br> <br>  <span>int</span> prRowId = dlm.FindAcPpRowId(partId);<br>  <span>PnPRow</span> prRow = db.GetRow(prRowId); <span>// not used yet</span><br> <br>  <span>// remove all line groups already related </span><br>  <span>// to this pipe, if any, to avoid this pipe</span><br>  <span>// belong to multiple line groups</span><br>  <span>PnPRowIdArray</span> priorGroupIds = dlm.GetRelatedRowIds(<br>    <span>"P3dLineGroupPartRelationship"</span>, <span>"Part"</span>,<br>    prRowId, <span>"LineGroup"</span>);<br>  <span>if</span> (priorGroupIds.Count != 1)<br>  {<br>    <span>foreach</span> (<span>int</span> id <span>in</span> priorGroupIds)<br>    {<br>      dlm.Unrelate(<span>"P3dLineGroupPartRelationship"</span>,<br>        <span>"LineGroup"</span>, id, <span>"Part"</span>, prRowId);<br>    }<br>  }<br> <br>  <span>// make the relation</span><br>  <span>if</span> (lgRow.RowId != -1 && prRowId != -1)<br>  {<br>    dlm.Relate(<span>"P3dLineGroupPartRelationship"</span>,<br>      <span>"LineGroup"</span>, lgRow.RowId, <span>"Part"</span>, prRowId);<br>  }<br><br>}

And here is a simple command to invoke this routine
