The Etransmit tool in AutoCAD is used by our teams when packing or sending information to the owner or client. Revit does not have a standard tool for etransmit however there is an add-on created by the Autodesk Lab.

With eTransmit for Revit, you can:

§  Copy and detach a Revit model and associated files to a single folder for internet transmission. This removes the typical error messages when you copy central files using the operating system.

§  Locate dependent files automatically and include them in the transmittal folder, helping to reduce the possibility of error. All dependent files are automatically converted to use relative paths so the dependent files can be located by the model.

§  Choose to include related dependent files such as linked Revit models, CAD files, DWF™ markups, decal images, and external keynote files. You can transmit any Revit (.rvt) model that has been upgraded to be compatible with a 2012 Revit software product.

§  Transmit models that are using file-based worksharing or server-based worksharing. eTransmit for Revit will also work with non-workshared Revit models.
