In order to create perfectly horizontal or vertical mirror lines use Ortho. They are usually the most commonly used and you need only right-click and select "Enter" from the menu or press on the keyboard to accept them. Many AutoCAD commands offer default options. AutoCAD always shows the default option within triangular brackets, in this case "". This is because "No" is the default option. Notice that in the command sequence above, pressing the key when asked whether to "Delete source objects?" resulted in a "No" response. Specify second point of mirror line: (pick P3)ĭelete source objects? : (for No to keep the original object) Specify first point of mirror line: (pick P2) Select objects: (pick object to mirror, P1) The Mirror command allows you to mirror selected objects in your drawing by picking them and then defining the position of an imaginary mirror line using two points. The two points are simply used to indicate the distance and direction of the copied object from the original object. Notice that the "Base point", P2 and the "Second point", P3 do not have to be picked on or near the object. To end a multiple copy, just hit the key. The multiple option allows you to create additional copies of the selected object(s) by picking as many new points as you like. Specify second point of displacement or : (pick P3) Specify base point or displacement, or : (pick P2 Select objects: (pick object to copy, P1) Copy is a very useful and time-saving command because you can create very complex drawing elements and then simply copy them as many times as you like. The Copy command can be used to create one or more duplicates of any drawing object or objects which you have previously created. See the " Object Selection" tutorial for more information on selecting objects. The last object will be highlighted and you can then select more objects or to end the command. If you simply want to erase the last object you created you can type L at the "Select objects" prompt. Select objects: (to end the selection and erase the object) Select objects: (pick an object to erase) Remember you can always get deleted objects back by typing U to undo, from the Standard toolbar or by using the OOPS command. The command erases (deletes) any selected object(s) from the drawing. The Erase command is one of the simplest AutoCAD commands and is one of the most used. Many AutoCAD users work with the Modify toolbar permanently docked on their screen because it gives one-click access to all of the commands, making the drawing process much more efficient. When the Toolbar dialogue box (shown above) appears, simply check the box next to "Modify" in the toolbars list. The Modify toolbar is usually displayed by default but if it is not already displayed, you can display it using the TOOLBAR command, View Toolbars… from the pull-down menu. That said, it should be pointed out that the use of toolbars in AutoCAD is almost always quicker than any other method. AutoCAD allows great flexibility and there aren't any right or wrong ways of working. Ultimately you will use the method that you feel most comfortable with or the one you find most efficient. The method you choose is entirely up to you. In each section below, the toolbar, pull-down and keyboard options are given. All of the Modify tools are available from the Modify pull-down and the Modify toolbar. If you just need information quickly, use the QuickFind toolbar below to go straight to the information you need or select a topic from the contents list above.Īs is usual with AutoCAD, the Modify tools can be accessed in one of three ways, from the keyboard, from the pull-down menu and from the toolbar. This tutorial is designed to show you how all of the Modify commands work. However, the way these commands work is not always obvious. As you can see, the command names are easily understandable. AutoCAD provides a whole range of modify tools such as Move, Copy, Rotate and Mirror. Most likely you will need to Modify these basic drawing objects in some way in order to create the image you need. AutoCAD drawings are rarely completed simply by drawing lines, circles etc.
