Myself and Fred901 are endeavouring to make accurate airfields. One of the most vital things to do is correct the E pens, and replace what was sheer fiction with accurate Belfast Truss Hangers seen at airfields such as Kenley, Duxford, Fowlmere etc etc.

I am able to draw these in CAD, how do we go about adding them in ?

WE are also finding that some structures are needing removal, but cannot see a way of doing so, what help is there on this ?
Perhaps they can be coded to be well away from the airfield !
