Ok, that's easily do-able Birdy. Although, isn't this what the wonderful folks at Autodesk gave us the Sheet Set Manager for?
J/k.
The entity manipulation is also a very good one. VBA gives us almost total control over all the aspects of a drawing object's properties, but very few of the modifications are available directly. (ex. trim, break, move, copy) You can still do all of those, but you have to know your way around to be able to pull it off.
For file I/O, are you talking about text files, or dwg files?
heh, "blocks" will be fun. Since "blocks" and "blockreferences" are two terms that don't come into AutoLisp very often.
As a given, any tutorials will seem easier for those versed in V-Lisp vs. those who only know AutoLisp. V-Lisp uses many of the same terms as VBA, and the way of manipulating objects is also somewhat similar.
I think that we can also work in the topics that Mark mentioned (private and public subs and functions) at the same time.
