How to mirror objects without selecting points to define the mirror axis in AutoCAD?
If you are an AutoCAD user, you know how powerful it is to work with the MIRROR command. The MIRROR command allows you to create a mirror copy of selected objects across a specified line. The MIRROR command can help you create symmetrical and balanced drawings, as well as save time and effort.
However, sometimes you may find it annoying or inconvenient to select two points to define the mirror line every time you use the MIRROR command. For example, you may want to mirror objects across a predefined axis, such as the X or Y axis, or across an existing object, such as a line or a polyline. In these cases, selecting two points can be redundant or inaccurate.
But what if I told you there is a way to mirror objects without selecting points to define the mirror axis in AutoCAD? Yes, you heard me right. No points. And you don’t need any special software or plugins to do it. All you need is a simple AutoCAD LISP routine that you can load and run in your AutoCAD session.
After you have uploaded the LISP file, you need to type 'QM' to activate it.
Then select the objects.
Finally, select the mirror object.
That’s it. You have successfully mirrored objects without selecting points to define the mirror axis in AutoCAD using a LISP routine. You can use this LISP routine as many times as you want, on any drawing that you want. You can also customize the LISP routine to suit your needs, such as changing the erase or copy mode of the original objects.
You can download the lisp from here.
