This tip works begining with AutoCAD 2006:
At the command line, type the first letter of the command you wish to start. Do not press
(ENTER); instead, press the TAB key repeatedly and watch as AutoCAD runs through an alphabetical list of all commands, beginning with the letter you first typed. When the right command appears in the command line, press
to start it.
This isn't a very efficient way to invoke a command but it's a great way of finding commands you never knew existed; try it yourself and you will discover that AutoCAD has a lot of commands…
Also, you can press SHIFT+TAB to walk back through the list.
By default, AutoCAD always displays the UCS icon at the drawing origin (0,0) unless the origin is off screen, in which case, the UCS icon sits quietly in the bottom left-hand corner of the drawing area.
If you find the UCS icon distracting when it's floating in the middle of the screen, you can force it to be displayed in the bottom left-hand corner using the ucsicon command.
Enter an option [ON/OFF/All/Noorigin/ORigin/Properties] <ON>:
Use the "Noorigin" option to force the icon into the bottom left corner and the "ORigin" option to set it back to the default.
See the UCS Icon tutorial for more details.
Most AutoCAD users know about the undo command, which allows you to step back through the command sequence. This is useful if you make a mistake and need to retrace your steps. But what if you deleted something a while back and in the meantime you did some useful stuff that you don't want to lose in order to recover your deleted stuff. Oops to the rescue!
The oops command recovers the last deleted selection set, without undoing everything in-between. It can also be used to recover objects removed after using block or wblock.
Have you ever wanted to see your name or your company's name displayed on the AutoCAD status bar? If so, you need to know about the modemacro variable. Whatever value you set this variable to will appear on the status bar, just to the left of the dynamic co-ordinate display. To do this, enter "modemacro" at the command prompt and then enter the text you'd like to display.
The assigned value of modemacro remains set only for the current drawing session. If you's like to see your text displayed every time you start AutoCAD, simply add the following line to acad.lsp:
(setvar "modemacro" "text to display")
When drawings get crowded with lots of detail, it can be difficult to select the required snap point with running object snaps. Invariably, the snap point AutoCAD finds is not the one you want. This is where object snap cycling comes to the rescue. With running object snap turned on, hover the cursor close to the snap point you want and hit the Tab key on the keyboard to move between the various possible snap points near the cursor. Keep hitting the Tab key until you find the snap point you want. When you've got it, left-click to select the point.
Are you an expert in AutoCAD? Well according to Autodesk you aren't, well not unless you tell the program otherwise. The EXPERT system variable (default 0) can be changed so that annoying "Are you sure?" commands will go away. Here is the list and what they do:
The Imprint command ( ) gives the first impression of nothing more than adding graffiti to solids. Upon closer investigation, however, we find that it actually modifies the face on which it is placed, effectively sub-dividing it. Sub-divided faces can then be extruded using the Extrude faces command ( ).
To generate this modified part with Boolean operations would not be difficult but, as we all know, speed and accuracy are the name of the game. The procedure describe above can be auto-executed with the command macro:
^C^C_line;\\;_solidedit;b;i;\last;y;;;f;E;\;\\;;
The UI could benefit from some advanced programming, but if one pays attention to the Command Prompts, it's not so bad.
Note: This tip relates to versions of AutoCAD before 2007. Although the technique works with 2007 and above, the same operation can be achieved more easily using the Presspull tool.
