It seems DXF files can be accessed with JavaScript. This sounds a bit peculiar to me, how big are these files?

Can be very big http://medw.co.uk/fisheye/view.php?gallery_id=36 will give you the idea. I'm dumping the images to jpg from Turbocad, so I have separate thumbnails to drawing files, but ideally if people are uploading drawing fiels we will need to automatically produce thumbnails for them. server end rather than client -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/lsces/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php
