why is the coordinate different in dxf which I export and in revit?

[27925916]

I use the codes to export dwg in revit to dxf file,but the coordinate is not the same between dxf and revit?

            string DXF_Folder = "G:\\";
            string DXF_File = "tmpdxf";
            List<ElementId> list = new List<ElementId>();
            list.Add(app.ActiveUIDocument.ActiveGraphicalView.Id);
            doc.Export(DXF_Folder, DXF_File, list, DXFoptions);

I try a test to pick a line in revit and find it's coordinate is different with the one in my exported dxf.  And I find the revit's own function of exporting dxf could make the coordinate same between in dxf and in revit.

is any suggestion to my code for exporting dxf? thanks much..

Hi @27925916,

Have you tried modifying the SharedCoords property of DxfExportOptions? http://www.revitapidocs.com/2017.1/1a291c40-65d6-cae1-a69c-e60ef026645a.htm

The TargetUnit property may have bearing also.
