trim and erase outside polyline

[sodeepva]

Hi,

Is there a LISP routine available or a series of commands in ACAD 2006 that would trim and erase all elements outside a specified polyline (shape)? The command EXTRIM works fine as far as trimming everything at the polyline, but then I would like to erase any elements left outside the polyline. Thanks for any help with this.

...after using Extrim

I use ToolPac (http://www.dotsoft.com/toolpac.htm), Object, Erase, Outside Objects (or Inside Objects depending on situation).

Manually, you could do an Erase ALL, then do a remove using a Window Polygon, picking the points of the polyline.

Or create a lisp to do the above.

Thanks for your suggestions. I ended up creating a script file that does an erase all, then remove, etc. Is it possible to create a LISP routine with EXTRIM at the beginning followed by a command to activate the script file? Thanks again.

(defun c:foo ()
(c:extrim)
(command "._script" "test.scr")
)
