Export to DWG and automaticaly bind images

[1161314]

Hi,

Is it possible to make revit export to dwg and binding any images that are placed in the sheets? Something like e-transmit in autocad. 

Thanks

If you can achieve what you wish manually in the user interface, then it can probably be driven programmatically by the API as well.

I didn't understand your answer. I was asking if is possible to write na addin for revit that manipulates dwg files. In concrete, to bind images in files exported from revit.

Can you achieve what you need manually in the user interface?

[1161314]

In the Revit interface no.

In autocad, is the etransmit command. Can i cal that command in na addin runnig in Revit?

[jeremytammik]

The Revit API does not support this. It only supports activities that can also be run manually through the Revit user interface.

However, you can in fact make use of the AutoCAD.NET API as well as the Revit API inside your Revit add-in.

So that should be possible.

So far i've done this:

        public static void Etrans(string desenho,string destination)
        {

            try
            {
                TransmittalFile tf;
                TransmittalOperation to = new TransmittalOperation();
                TransmittalInfo ti = to.getTransmittalInfoInterface();

                System.Windows.MessageBox.Show(desenho);
                to.addDrawingFile(desenho, out tf);

            ti.destinationRoot = destination;

            ti.preserveSubdirs = 0;


            ti.organizedFolder = 0;

            ti.dataLinkRelativePath = 1;
            ti.DGNUnderlayRelativePath = 1;
            ti.DWFUnderlayRelativePath = 1;
            ti.imageRelativePath = 1;
            ti.PDFUnderlayRelativePath = 1;
            ti.xrefRelativePath = 1;

            ti.saveVersion = SaveDwgFormat.eAutoCADR21;

            ti.visualFidelity = 1;

            ti.includeXrefDwg = 1;
            ti.includeUnloadedReferences = 1;
            ti.includeUnloadedXrefDwg = 1;
            ti.includeNestedOverlayXrefDwg = 1;

            ti.BindType = BindType.eBind;

            ti.depathXrefs = 1;

            ti.includeImageFile = 1;
            ti.includeDGNUnderlay = 1;
            ti.includeDWFUnderlay = 1;
            ti.includePDFUnderlay = 1;
            ti.includeDataLinkFile = 1;

            ti.includeFontFile = 1;

            // Reset plotters for layouts in the drawings to None, 
            // and include plot style (CTB/STB) files (0 - False, 1 - True)
            ti.resetPlotter = 0;
            ti.includePlotFile = 0;

            ti.includePhotometricWebFile = 1;
            ti.includeMaterialTextureFile = 1;

            ti.purgeDatabase = 0;

            }
            catch (Exception ex)
            {
                System.Windows.MessageBox.Show(ex.ToString());
            }
            
            try
            {
                //to.createTransmittalPackage();
            }
            catch
            {
                System.Windows.MessageBox.Show("ERRO");
            }
        }

And call it here:

foreach (var f in files)
                    {
                        MessageBox.Show(pathArquivo);
                        if(f.FullName.Contains(".dwg"))
                        {

                            ZiTools.Etrans(f.FullName, pathArquivo);
                        }

But i get this error:

I've created the interop "TRANSMITTALLib.dll" as indicated here:

To simplify matters, it ill probably be safest for you to develop your AutoCAD.NET add-in as a stand-alone app first, before trying to run it within a Revit add-in. That way, you eliminate one potential cause for problems. If you have any problems in that scenario, I would suggest raising them in the AutoCAD.NET discussion forum.

I've managed to get the dwg database, but i get na error in transation:

Just for the record, i've made it. But i had to use cad core manager.
