DWG to Caddy++/SEE electrical conversion

We have a client that wants electrical diagrams in Caddy++/SEE electrical format. We use a different CAD program that can export in DXF. This file can be imported into Caddy++/SEE electrical and then hopefully edited/adjusted so we can generate a file for the client. For this to work you have to have the SEE/electrical CAD software. Please advise which version you have so I know what you are working with.
