What Version was a dwg drawn in?

[Darren Allen]

Can someone tell me how to check a drawing to see what version it was drawn in and saved as? Please advise. Thanks

When you first open a drawing it says "Opening an AutoCAD xxxx format file." Where xxxx is the year. I'm not sure of any other way.

Ok, that's one way but I have to use F2 to read it. Is there any other way without opening it?

Open it in Notepad and read the header. You will have to open it somehow in order for a program to read the info.

Thank you both for your answers. I will choose to use the F2 as Note pad is a bit harder to decipher.

Notepad is much simpler and faster-- the value that identifies the file version is the very beginning of the file. fer example, opening a 2011 c3d in notepad shows the character string AC1021 as the initial characters of the file.

yes, this true that the first thing is AC1018 but deciphering the 1018 requires a cross reference unless you know what the 1018 means in laymans terms. F2 tells you right away; "Opening an AutoCAD 2004/LT 2004 format file." Thanks

Tom, I believe he wanted the version of the file that was opened, not the current product.

Yes, what version the file was created in and last saved as.
