Trim objects outside or inside of polyline object/s

Anybody can help make a lisp routine that automatically trim the xlines, lines, or polylines passing the closed polyline (or circle, ellipse, polygon).

I'm designing a scheme for subdivision having a numbers of Xlines, lines or polyline passing on a Block (closed polyline/polygon). I want it on once, all the said objects trim whether outside or inside the object.

There must be an option of Outer or Inner. If I select Outer, all the objects passed outside the closed polyline/polygon (as cutting edge) will be trim and all the objects inside this closed polyline remained.

Else, If I select Inner, all the objects passed inside will be trimmed/delete and all object passed outside will be remained.

Thank you for help!!

Express tools EXTRIM?

You must be not familiar with the command call extrim

:)Hehehe!! Yap!

Thank you Tharwat and pBe.

Using EXTRIM you can only select one object at a time. If there is anybody who can make as what I ask above, I really appreciate it.

Thanx!

can EXTRIM could be used to remove any object(eg:text, block,...)?

Try "Cookie cutter".lsp it does a real chomp of objects search here or goggle for a new version. It trims blocks etc
