Thanks . I've uploaded a lxf-file (LDD) of the bridge on mocpages several months ago, but I somehow forgot to post this in the first post (I added the download link at the end of the entry post now).
Uploading the whole L.M.S. Explorer is possible, but in my opinion only the file for MLCAD is usable (a.k.a. it loads fast, but the controls of this program aren't that easy), because the ship contains ~57000 bricks and is almost 8 metres long.
