Copy polylines between dwg files using script

[Andrzej_K.]

Hi,

I was looking for some script to copy objects (not blocks) from multiple .dwg file to another. 

Ideally I wanted to open the destination file. Run the script and the rest will be done for me.

I have found this code:

; by alanh copy a window from another dwg
; Nov 2019
(defun openblk (blkname / adocs)
(setq acDocs (vla-get-documents (vlax-get-acad-object)))
(vla-open acDocs blkname)
(command "copyclip" "w" "13,30" "402,276" "")
(vla-close (vla-item acdocs 1) :vlax-false)
(command "pasteclip" "0,0")
)
(openblk "d:\\acadtemp\\2circs.dwg")

 But when I was running it I got some errors: 

"1; error: Automation Error. Drawing is busy."

I did some small editing (apart from changing the file address and selection range) - in the function definition it looks like there was a spelling error and "adocs" should be "acdocs" but it did not solve the issue.  

Can you please assist?

That is an old one I think we just used it to open a dwg.

Try this as a script should work, you can write a script just use (command "script" filename)

(command "open" "d:\\acadtemp\\timber-edge.dwg")
(setvar 'ctab "MODEL")
(command "copyclip" "w" "13,30" "402,276" "")
close N
pasteclip "0,0"

Seems simple enough but when I use "open" I have a popup window from our database software which stops the process so in this case it will not work.

Try this sounds like Open has been redefined. This should work.

(command "._open" "d:\\acadtemp\\timber-edge.dwg")

Some time ago I wrote this program that copies objects between sessions.

Maybe you will find it interresting. It works with two opened sessions but I you need it to work with more than 3 sessions you can adjust it in code yourself.

Hi guys, thanks for the answers.

@Sea-Haven - I still need to figure out the .dwg issue in your code (AutoCAD struggles with it "Unknown command "DWG".")

@andkal - I would need to take a deeper look. This would require me to open each document manually and run the command separately for each which is something I'd like to avoid. 

In the end I have found some code here that does more less what I need.

I am using the code I have mentioned and I run into the problem. 

It works fine for dwg files (dwg to dwg). 

When I want to use it on dxf (dxf to dwg) (I am switching the file extension), CAD allows me to select the source file but then error shows. 

However, if I manually open the source dxf, and run the command in the dwg the program will work. 

My guess there must be an issue with LISP not being able to open dxf.

Can you help?
