Write Block Without User Input

I am stuck on the syntax to write a block without user input.

On executing the lisp, I want it to get a selection set from a variable and then write it to a new block without asking the user for input. The basepoint can be "0,0,0" and the file path is a pre-set path.

The general command I'm trying to use goes like this (I know it's wrong, but I don't know where to go from here)

(command "-wblock" "C:\\Users\\DefaultUser\\Desktop\\ScriptTest\\Blocktest1.dxf" "0,0,0")

I've searched LISP routines all over the place but can't find one that does this. I'm mostly looking for examples that contain a similar line of code.

1) I don't think that you can WBLOCK to a dxf format.

2) To export as a new block try :

(command "_.WBLOCK" file_name "" '(0 0 0) 'pickset "")

If you need to retain the entities

(command "_.OOPS")

I'm having trouble making that work. I tried testing it out in a new file in VLIDE. The console history is:

3 found

_.WBLOCK Enter name of output file:

C:\Users\DefaultUser\Desktop\ScriptTest\\Blocktest1.dwg

Enter name of existing block or

[= (block=output file)/* (whole drawing)] : Specify

insertion base point:

Select objects: ; error: bad argument value: AutoCAD command: PICKSET

here's what I have so far. Is there something I'm doing wrong?

(defun c:testingwb ()

(setq pickset (ssget))
(setq file_name "C:\\Users\\DefaultUser\\Desktop\\ScriptTest\\Blocktest1.dwg")
(command "_.WBLOCK" file_name "" '(0 0 0) 'pickset "")
(command "_.OOPS")
)

As a side note, I'm in love with the command:

(command "_.OOPS")

It's great fun.

Because you used (setq pickset (ssget)) you do not use the single ' with any references to the variable

(set 'picksert ...) vs (setq pickset ...) vs (set (quote pickset...)) vs (set (read "PICKSET") ....)

HTH -David

Oh WOW That was my BAD in post #2 Sorry ! That will teach me not to test snippets of code !

The following works for me in 2014.

The second function will let you export a selection set to DXF.

(defun c:testingwb ()
 (setq pickset (ssget))
 (setq file_name "C:\\temp\\Blocktest1.dwg")
 (command "_.WBLOCK" file_name "" (list 0.0 0.0 0.0) pickset "")
 (command "_.OOPS")
)

(defun c:dxfobj ( / pickset filename)
 (setq pickset (ssget))
 (setq file_name "C:\\temp\\Blocktest1.dxf")
 (vl-cmdf "_.dxfout" file_name "_O" pickset "" "16")
)

Greatness has been beheld on this day. Thank you very much, both of you! I am one step closer to sanity.
