Select distant objects

Is there any way to select by lisp distant objects, without user intervention.

Maybe by the larger coordinates in all 4 quadrants?

Thanks

SELECTALL?

I have "negative" hatches in many DWG files, located far away from the drawing and I want to delete them (not manually).

I don't see how you would be able to do this without any user input.

At the very least I should think you would need to define the extents for all objects which you do not wish to delete.

A simple way is to select all with Ctrl+A. Then press Shift and deselect everything on the screen.

The distant object should remain selected and you can Erase them.

Let's try other approach.

A lisp for selecting all "negative" hatches.

negative = hatches which cannot be seen due to large scale

it can be a lisp for selecting all outside a defined zone.

Are you able to pinpoint this defined zone?

We can try, but if I write it, it would be exact the same approach as I described.

So if my suggestion works, then the lisp would work.

Did you try it?

That is exactly how I would do it too, Stefan.

What about prompting the user to input a range of hatch scale values to be avoided, so the fault won't be in your code:

_$ (<= 1 2 3)
T
_$ (<= 1 0 3)
nil
_$ (<= 1 4 3)
nil
