AutoCAD 2022: A lisp file that can “erase” ALL what’s inside or outside a particular boundary in one go,

I’m wondering if there is a lisp file that can “erase” ALL what’s inside or outside a particular boundary in one go.

Do a search in this forum for ssget_inside (or I'll post it again if you can't find it).

One decision you will have to make is whether you want to use a "Window Polygon" or "Crossing Polygon" method because you have to remember that while a circle, or block, or text can have its insertion point inside the boundary, there may be parts that extend outside, and vice versa.

See attached ... no need for code.

Thank you john.uhden. I would appreciate if you could provide me with the lisp file

Thanks ronjonp but I want this command so that I can use it for other drwaings

You can also try SMARTSEL.

Unfortunately, I’m not a developer and have no background how to write lisp files

Try CookieCutter2  (type CC in system console)

No time for a coffee as cookie cutter is very fast used it for years.

I have added the lisp file but appears not to be detected by the AutoCAD as per the screenshots below

What could be the issue here?

@JamaL9722060 

At the bottom of the code it says
(defun c:CC () (CookieCutter2))

To run lisp command in console this function name has to start with c:

TYPE CC to system console to run CookieCutter

It works like a charm. Amazing. Thank you for the help

CookieCutter is very impressive! 👋 Thanks for sharing.

One modification I would suggest: instead of exploding the blocks that cross the selected trimming object, use the XCLIP command instead and simply clip the block. There are a few benefits of this:

• The block is still "trimmed" even if it's a non-explodable block. 
• it retains the attribute value
• The attribute's text value is "trimmed" as well!
• The XCLIP option can also be applied to xrefs that cross the trimming object

Alternately, perhaps use BURST instead of EXPLODE on the block if it contains any attributes.

@hak_vz ,

If you've got Civil 3D there is a MAPTRIM command.  It figures out the boundary from the objectS you select and you have the choice of trimming/erasing what's inside or out.  It's amazing.
