Remove object in locating outside boundary

Anonymous — Thu, 16 Feb 2017 12:17:01 GMT

Hello.

I want to delete all of the things that is located outside some boundary.

I attach an example image to you to understand it.

The image is that I want to remove circle in locating outside the rectangle.

Because my project has a lot of circles that I can not delete individually.

In time that it took you to type your question you could have erased the circles outside the boundary individually. In a more complicated drawing there are several ways to accomplish what you want but not in the way you think it should work.

In you example, I would select all the circles and then deselect using shift and a window or crossing window.

Alternatively, you could make a block of what you want to keep, erase everything and then insert the block.

There is no built-in inverse selection for AutoCAD.

Rob's method of selecting all and shift-select for item to deselect from the set is the simplest way.

Using LISP at the command line (ssget"X") selects the ENTIRE database of objects in the file, including off/frozen layers. Then enter an R for remove and select those objects you wish to keep (via window, crossing, fence etc.). Objects on locked layers, or in "other" space will not be altered.

Hi @Anonymous,

As others have suggested, there is no inverse selection available in plain AutoCAD. So the easiest way is to ERASE all and then remove the items you want to retain before completing the command.
