Just open a DWG drawing with the required border in to a blank dft file suitable for your requirements. Its best to use a clean DWG with just the border. then tidy up any poorly translated text and save as a draft.
There is an options button (bottom left of open diologue) this works like a wizard and will lead through layers, line weights, fonts, colour matching etc.
Note any autocad links or auto-text will be lost so you will have to re-establih those with SE properties.
