Feature Request : Rhino Document Guid / ID

Rhino Developer

Hi Dale,

Many thanks for the plug-in sample you posted above. It works well when copy-pasting the document, as the newly created one keeps the same GUID as the original one. Is there anyway to fix this in the script?

Below, I tried to overwrite the “DocumentId” key when e.Merge is True as I understood from this post that a Paste operation is the same as Import. But that attempt was unsuccessful. Ideally, Pasting would overwrite the DocumentId but importing or insterting a Rhino file into an existing one that already has a “DocumentId” would leave it as it is.

I hope this makes sense…

    private void OnEndOpenDocument(object sender, DocumentOpenEventArgs e)
    {
      if (!e.Merge && !e.Reference)
        SetDocumentId(e.Document);
      if (e.Merge)
        SetDocumentIdCOPY(e.Document);
    }

    /// <summary>
    /// Sets the document id, if needed.
    /// </summary>
    /// <param name="doc">The document.</param>
    private void SetDocumentId(RhinoDoc doc)
    {
      if (null != doc)
      {
        var doc_id = doc.Strings.GetValue(KEY);
        if (string.IsNullOrEmpty(doc_id))
          doc.Strings.SetString(KEY, Guid.NewGuid().ToString());
      }
    }

    private void SetDocumentIdCOPY(RhinoDoc doc)
    {
        if (null != doc)
        {
            //var doc_id = doc.Strings.GetValue(KEY);
            //if (string.IsNullOrEmpty(doc_id))
            doc.Strings.SetString(KEY, Guid.NewGuid().ToString());
        }
    }
