How to Flip Drawings in AutoCAD
By Laura Gittins
In AutoCAD, you can flip part or all of what's on your canvas by using the "MIRROR" command, which takes a selection and inverts it. By default, AutoCAD simply creates an inverted duplicate of your selection, except for any text objects within the selection -- that remains the same. You can choose to delete the original selection. Alternatively, by changing the "MIRRTEXT" system variable when using the MIRROR command, you can also flip any selected text as well.
Click the "Home" tab followed by "Modify panel" and "Mirror" to select the Mirror command. Alternatively, type "MIRROR" into the command search bar and click on "MIRROR Command" when it appears. To make any text you select mirror as well, instead type "MIRRTEXT" into the command search bar and type "1" at the end of the line to set the variable's value.
Click and drag your mouse over an area on the canvas that you want to mirror, which selects the area.
Click a point on your frame to specify one end of the mirror line. Move your mouse to another point on the screen and click again to specify the other end of the mirror line.
Press "Enter." The objects you selected will appear mirrored on the other side of the line you drew, including text if you set the "MIRRTEXT" variable to "1." Alternatively, press the "Y" key to create the mirrored objects and delete the originals at the same time.
You can mirror objects on a 3D plane by selecting the "3D Mirror" command instead of "Mirror" from the "Modify panel" options. Next, select three points for your mirror instead of two.
