Is there a way to determine what version of AutoCAD a DWG file was created in?

not as i know of - but when you open the drawing - go to drawing properties - there you can find out the creation date...

Hi

Does the following thread offer anything helpful / useful...

Have a good one, Mike

Not sure about "created", but to find the version in which it was "last saved"...
Open the file in Notepad (or some other ASCII or HEX editor) and read the first 6 bytes

AC1021 = 2007
AC1018 = 2004, 2005, 2006
AC1015 = 2002, 2000i, 2000
AC1014 = 14
AC1012 = 13
AC1009 = 12, 11
AC1006 = 10
AC1004 = 9
AC1002 = 2

If you want to do this from within AutoCAD using lisp, see http://groups.google.com/group/autod...25e7729?hl=en&

Here is a nice little program that will tell you the current version while looking in explorer.

That's pretty slick. Have you installed it?

I just tried it and it slows down browsing a bit when in a directory full of drawings, but not as much as I thought it might.

I think it might be a keeper...

I've been using it for about as long as 1.6 has been around. Love it! Never an issue. No explorer crashes, etc.
Start poking in an older folder and it's amazing to see all the different CAD versions that will pop up as you browse.
