This year I decided to wait until the release of the British English language version of Civil 3D this year before published my help documentation to the country kit. So I have posted it online.
To download it click this link
Also new this year I have put together a couple of videos to explain what the country kits are and how to install them and some of the detail of what the UK and Ireland kit entails.
You can find it by clicking this link
Or by selecting the links from the tool palette if you are using the UKIE icon to start AutoCAD Civil 3D 2013.
