There are times when you are using the EXTEND command to Extend objects to a boundary edge, you also have to TRIM objects to that same edge (or vice versa)

Instead of having to stop one command and then start another, you can simply hold shown the SHIFT key on your keyboard to toggle between the EXTEND and TRIM commands.

For example: If you are in then middle of the EXTEND command, and then you need to TRIM some objects, hold down the SHIFT key; select the object to trim; and when you are done trimming, let go of the Shift key, and you will be back in EXTEND mode.

If you need to EXTEND and TRIM a series of lines to the same edge, there is a quick way to accomplish this within one command.

• First, make sure your ORTHO is turn on.

• Then, enter the command CHANGE and select the endpoints of all the lines you need to Extend or Trim

• Finally, pick the point where you want these endpoints to Extend or Trim to.

The Save Command

One of the most misunderstood commands in AutoCAD is the SAVE command. Note that SAVE, QSAVE, and SAVEAS all do different things.

•SAVEAS saves the current drawing to a new file name. Example: If you are working in "A.DWG" and you run the SAVEAS command and specify "B.DWG", then "B.DWG" is created and is now the current drawing in the editor.

•QSAVE simply saves the current drawing. If the current drawing is unnamed (not yet saved) or it is read-only, then QSAVE behaves like the SAVEAS command and allows you to specify a file name and location.

•SAVE writes the contents of the editor to disk. It is like SAVEAS in that you get to specify the file name and location, but the currently loaded drawing remains unsaved and unchanged, even though DBMOD is reset to zero in the current drawing. Using the above example, if you are working in "A.DWG" and you run the SAVE command, and specify "B.DWG", then "B.DWG" is created from the contents of the editor, but "A.DWG" remains loaded, unchanged, and unsaved.

The exception to this rule is that when the SAVE command is executed in an unnamed drawing, it behaves like the SAVEAS command and names the current drawing.

To confuse things even more, the pull-down menu entry titled SAVE, actually executes the QSAVE command. The SAVE command is only available at the command prompt

This is useful to know you have done a fair amount of work, used QSave a few times. and realize that you should have saved the file to a new name. To recover from this you can do one of the following:

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.

Next follow steps 2 & 3 in the previous example.

Method 3:

Step 1) in windows explorer, locate 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.

You may have different versions of AutoCAD (2004, 2007, 2008) installed on your system as well as AutoCAD LT 2006 and AutoCAD Architecture 2009. All of these applications open .DWG files. If you want a specific program to open a file that you have selected in Windows Explorer simply edit the following regisry key:

"C:\Program Files\AutoCAD 2010\acad.exe"

The \AutoCAD 2010\acad.exe directory defines which application will be used as the default application.
