After a little break Project Basejump is back and running until August 2013 (that’s next year) for AutoCAD Map and Civil 3D 2013 users.
Its free and fast to use, just connect via the data connection (FDO) inside your ‘Planning and Analysis’ workspace, but ensure you have set the coordinate systems you are working in i.e. Great Britain, BritishNatGrid’
Then just choose the aerial or map that you want and connect, simple!
