There was some discussion last year re. Cad projects that people were
working on. I use Autocad 2000 all the time now for project design and
drawing. Now I've more or less worked out how to do things I find it a
godsend.

I've uploaded a couple of .dwg files (in the files section) for an 0
gauge live steam Royal Scot I am designing which may be of interest.
Not sure how compatable these are to other versions or other packages.

The great thing I find is that you can alter the scale of the drawings
when you print them out. For example, for the 0 gauge model I can
print them full size to use as templates for making parts (saves
marking out!). I could also print them twice full size for a 2.5"
gauge version or 4 times full size for a 5" gauge version.
