so you forgot to save the dwg to a new name...

Assuming that you open a file, then do a fair amount of work, QSave a few times.Then realize that you should have saved the file to a new name.

If you have not closed the drawing there is a way to save the work and restore the drawing back to the Original state.

Method 1:
Step 1) TYPE in "Save". and input the new file name.

(Note: Do not pick "Save" off a pull down or a toolbar as that will "QSave" to the current file name. It's interesting to note the difference between QSAVE, SAVE, & SAVEAS when typed at the command prompt. IF a drawing has been named, SAVE will make a copy of the drawing in what ever path you choose. IF you use the same path & name as the current drawing it will prompt for "overwrite". Otherwise it will make an exact copy but with a new name.)

Step 2) Use "Undo" "B" "Y" to get back to the original state.

Step 3) Qsave the drawing.

Method 2:
Replace Step 1 in the previous example with this
Step 1) use the "Wblock" command and select "Entire Drawing" and assign the new name in the path.

then follow steps 2 & 3 in the previous example.

Method 3:
Step 1) in windows explorer find the file and copy it, paste it in the new location (if needed) then rename it.

Then in AutoCAD follow Steps 2 & 3 as mentioned in the previous example.

I did a writeup on SAVE vs QSAVE vs SAVEAS a while back if anyone is interested.

Also, sometimes you cannot do step 2, especially if UNDO is turned off.

R.K.,
Good write up!

Also that's a good point about the UNDO command.
