Creating a new “Point Description Key sets” using Civil 3D .Net API

By Partha Sarkar

In this post, I will show you how to create a new "Point Description Key sets" and add Point code using wildcards "*".

//start a transaction 
using (Transaction trans = db.TransactionManager.StartTransaction())
{
 
  // Access the collection of all  Description key sets in a document          
  PointDescriptionKeySetCollection pointDescKeySetColl = PointDescriptionKeySetCollection.GetPointDescriptionKeySets(db);
 
  // Add a new Descp. Key Sets
  ObjectId PointDescKeySetsId = pointDescKeySetColl.Add("ADN_Point_Desc_Key");
  PointDescriptionKeySet pointDescKeySet = trans.GetObject(PointDescKeySetsId, OpenMode.ForWrite) as PointDescriptionKeySet;
 
  // Create a new key in the set with code = "TR*" 
  // The wildcards “?” and “*” are allowed in the code. 
 
  ObjectId pointDescKeyId = pointDescKeySet.Add("TR*");
  PointDescriptionKey pointDescKey = trans.GetObject(pointDescKeyId, OpenMode.ForWrite) as PointDescriptionKey;
 
  // set a specific Style and Label style
  // in the following line we are presuming a Point Style named "Tree" exists in the DWG file            
  pointDescKey.StyleId = civilDoc.Styles.PointStyles["Tree"];
  pointDescKey.ApplyStyleId = true;
 
  // in the following line we are presuming a Point Label Style 
  // named "Point#-Elevation-Description" exists in the DWG file
  pointDescKey.LabelStyleId = civilDoc.Styles.LabelStyles.PointLabelStyles.LabelStyles["Point#-Elevation-Description"];
  pointDescKey.ApplyLabelStyleId = true;
 
  trans.Commit();
}

Once you build your application using the above code snippet and run the custom command in Civil 3D 2013, you should see a new Point Description Key sets added to the collection like the screenshot shown below –

Hope this helps!
