AutoCAD Visual LISP / AutoLISP :: Redefine Existing Block
Jan 29, 2012
I am using the following function to create a block:
(defun crea-blocco (ip blockname gruppoogg / blkobj sArray c r vla-objects doc) (setq c -1) (repeat (sslength gruppoogg) (setq r (cons (ssname gruppoogg (setq c (1+ c))) r)) ) (setq r (reverse r)) (setq vla-objects (mapcar 'vlax-ename->vla-object r)) (setq doc (vla-get-activedocument (vlax-get-acad-object))) (setq blkobj (vla-add (vla-get-blocks doc) (vlax-3d-point ip) blockname)) (setq sArray (vlax-safearray-fill (vlax-make-safearray vlax-vbObject (cons 0 (1- (length vla-objects)))) vla-objects)) (vla-copyobjects doc sArray blkobj) blkobj)
But if I start this function two times with the same block name, I get a block with the selected objects added to the existing block.
How can I redefine an existing block with vlisp?

I am trying to redefine Block A to Block B, Block C & Block D based off the value of an Attribute in Block A.
If the Attribute in Block A is "1" then redefine to Block B
If the Attribute in Block A is "2" then redefine to Block C
If the Attribute in Block A is "3" then redefine to Block D
I know it should be able to be done using If and Cond functions within a lisp routine, but I am in a hurry with it and don't have the time to research it anymore.

I have the following code to redefine a block after a command has ended:
(vl-load-com);*********************************************************(defun Redefine() (command "_.INSERT" "reactortest=reactortest" nil)(princ "Block redefined."));****************************************(vlr-command-reactor nil '((:vlr-commandEnded . endCommand)));******************************************************(defun endCommand (calling-reactor endcommandInfo / thecommandend) ; Get the name of the command.(setq thecommandend (nth 0 endcommandInfo)); Check name of the command.(cond ((= thecommandend "PLINE") (Redefine)));cond(princ));defun(princ)
It doesn't work because INSERT is an interactive function and can't be called while a reactor is active. Is there another way to redefine a block that can be used in a reactor? The block is in one of the default search path's.

Is there a way to attached an already exisiting placed block to a leader. If so, is there a way to do it to all the existing blocks, that are of the same block definintion, at once?

I've written a script that improves the default "ID" command, but it's not working.
I was able to redefine the "DI" command.

I have this routine for using a selected arcs rad value as a new fillet rad. If you like, a "match fillet" routine:
;Fillet Copy
;Copies the Radius of an Existing Fillet or Arc;
(defun C:filletcopy ()
(setvar "cmdecho" 0)
(setq c1 (entsel "
Select Fillet to Copy:"))
(setq c1 (entget (car c1)))
(setq rad (cdr(assoc 40 c1)))
(setvar "filletrad" rad)
(princ "
Select Lines:")
(command ".fillet" pause pause)
)
I use the routine loads but could modify so it would pick up the value of a filleted polyline? As it stands it can only select an individual arc. I would like the routine to be able to pick individual arcs and/or filleted polylines, without exploding first, if possible....

Any way to override existing AutoCAD commands.
Lets try this. When a user types "line" at the command prompt, or hits the "line" button on the toolbar, or chooses "line" from the draw pulldown menu, is there any way I can re-write what line means and draw a circle? (Extreme example)
There are just some commands that I'd like to have a variable set in the background, depending on what the command is. So I'm thinking if I could re-write the "line" command, instead of trying to convince everyone to use and remember a custom command, it would be much more efficient. There are lisp files already loaded in their start-up suite. Not sure if that works.

I need the same funcionality as in code below, but without using "command".
The main idea is alowed user to modify Existing Selection Set.
(defun gt:ss->lst (a:ss / i lst ) ;_ / (setq i 0) (if a:ss (progn (repeat (sslength a:ss) (setq lst (cons (ssname a:ss i) lst) i (1+ i) ) ;_ setq ) ;_ repeat (reverse lst) ) ;_ progn ) ;_ if) ;_ defun gt:ss->lst(defun gt:ss_modify (a:en-lst / ) ;_ / ;;create Selection set (setq ss2 (ssadd)) (foreach f:en a:en-lst (ssadd f:en ss2) ) ;_ foreach ;;Run command and fill with initial content (command "_select" ss2) ;;Alow the user to modify the contents (while (/= (getvar "cmdnames") "") (command pause) ) ;_ while ;;get back the list of enames from modified selection set (setq ss3 (ssget "_P")) (setq ss3-lst (gt:ss->lst ss3))) ;_ defun gt:ss_modify(defun tst:gt:ss_modify ( / ) ;_ / (gt:ss_modify (gt:ss->lst (ssget)))) ;_ defum tst:gt:ss_modify

I get an AutoCAD drawing from my conveyor manufacturer who have buried a block (tagname) in all of their conveyor blocks.
The only way to remove them is to manually use BEDIT and erase the tagname block.
Is there a way through Autolisp to search all blocks in a drawings and if the tagname block is part of the definition of the conveyor block, erase the tagname block or redefine the conveyor block without the tagname block.

When dynamic blocks are inserted they're assigned an anonymous block name. I'd like to be able to retrieve the name of the parent block after selecting the block on screen using AutoLisp.
Need a bit of code that handles this?

Create a routine that looks for a block based on a portion of that block name, using a specified path or search path.
For example, block to search for is BLOCKABC123, so if someone inputs ABC or 123 as a block name, it will locate that block within that folder and inserts it into the drawing at a user specified location.
Ideally, if there is a check in that if it finds more than one match, then perhaps it flags or prompts you to choose 1, 2, or 3 option which block to use. But I can live without this special function if it requires too much time to code.

I need to match few attribute values from one block to different block. I download a lisp file called; ca.lsp which can match the single attribute value. I modified it for more than one attribute value matching. It is ok but still wish to overcome two issues for batch prcess
1. picking up the blocks by selection
2. click the alternative block numbers of times to match the numbers of attribute values I needed.
How to modify this lisp I can run it by block name selections instead of picking selection which enable me to run batch process for numbers of drawing? That will be good...
Lisp & Demo file attached (Match attribute value, A, B & C to Attribute 1, 2 & 3).

I am learning autolips and i found a problem that i can´t solved.
(vl-load-com)(defun c:pmb ( / ss ent pt )(prompt "
selec block : ")(setq ss (ssget '((0 . "INSERT")))) (setq ent (ssname ss 0)), (setq pt (cdr (assoc 10 (entget ent)))) (command "point" pt))
wich this code you select one block and insert one point at insert point´s block.
which this other code yo select all block and insert all point.... but in one block
(vl-load-com) (defun c:pmb11 ( / sele cod bloque nbloque lista pt ) (prompt "
block: ") (setq sele (ssget ( List'(0 . "INSERT"))) Cod 0 )cod (1+ cod) (repeat (sslength sele) (setq bloque (ssname sele cod)) (setq pt (cdr (assoc 10 ( entget bloque)))) (command "punto" pt) );repeat )

I'm working out a LISP for searching my entire drawing for a MLeader with a given value and then do something if it is found.
Currently, my code dies with

Lisp file to get serial letters and numbers from existing ones,
I got a lisp file (attached) from experts in the form which does generate serial letters and numbers from existing ones.
The issue with this lisp file is that it doesn’t give the opportunity to choose the direction of numbering (top to bottom/bottom to top/left to right/right to left) as shown in the screenshot below
How this lisp can be developed to give the user the chance to choose the direction of numbering?

I'd like to pass and existing set of selection to a command like laylck, which asks for selections after beginning the command.
It must be possible to do this. Some CUI setup, lisp routine?

I have attached 2 lisp files. datblkx5 makes a block of selection, inserts the block with a 5x distortion, explodes it, and corrects the text for width factor and text height. This one works fine.
I wanted to add the feature of scaling my selection with a user input value. This is the lisp datblkxxx. This one doesn't work. (that is it doesn't correct the text for width factor). I can't figure it out.

I have a block that i want to insert several times and revised each one to be different to do this i would have to insert it and rename the blocks that come in and then reinsert i would like to insert and have a lisp explode the main block and rename the other 2 blocks with a suffix at the end depending on how many times its in the drawing... can this even be done? My original block name that will be first inserted is "BENT PULLEY NOTES" it needs to explode after i drop it in and then there are 2 blocks within that called "Bent Pulley" and "Bent Pulley DYN" that i was hoping to keep the names but add a number at the end depending on how many are in the drawing already...
here is a lisp that i have found... it would work if i didn't have nested blocks and only wanted the one block to be insert and not explode...
(defun c:Test (/ e i name Bname )
(setq e nil)
(command "_.-insert" "Drawing1.dwg" pause "" "" "")
(if (setq e (entlast))
[Code] .......

I have a dwg with 40 blocks that have a non-annotative property. I can go through 1 by 1 and change the property to annotative and redefine the block. Is it possible to automate this? I have done some google searches but have not found anything I am able to cut and paste or put together to get it to work.

The crux of the matter is that the CANNOSCALE value needs to match an existing named scale. This lisp is part of a bigger lisp and I need to pass a variable into it. Here's what I have:
(setvar "CANNOSCALE" (strcat "1" = " (rtos variable 2 0) "'"))
But I get this error when I try to run it.

I have a slightly unusual query that I can't seem to find a solution for elsewhere. I have an existing OS plan that is 'off grid', and would like to adjust the vertices at the ends of all the existing lines and polylines so that they all sit on a grid point, ie round all vertices to the nearest whole number. Is there a quick command or script that does this?

I am trying to select all blocks of a certian name. I am using the following:
(setq ss1bk (ssget "_X" (list (cons 2 blkname))))
My issue is that this will not select any dynamic or attribute blocks that are not at the default insert state.
how to select all of a block by name including reguardless of current state?

I have a routine that counts dynamic blocks by visibility state and stores that information then prompts for scale and color and stores that information. Then a legend begins to build from the data and a collection of blocks to reflect the dynamic blocks and their visibility state. Everything works great on all of the machines around the office except on one. When the legend begins building, the one user is getting the DDATTE dialog instead of allowing the values to populate as expected. So, I had him change ATTREQ to 0 an run again. No deal, the same thing happens again and again. And; it only occurs on the one machine.

I need to get VLA-Object from block name.
here there is a code to get block name from VLA-Object:
(vlax-get-property obj (if (vlax-property-available-p obj 'EffectiveName) 'EffectiveName 'Name) )
but I need the inverse of this code exactly:
blockname(as a string)==>VLA-object
(defun GetVLA_BName (BName).......
so, how can I do it?

We have a block contain 10 attibs to be seen with 8 differents scales making 80 attribs! (We use that before Annotative features). When we edit this block, we have a LISP that ask for the 10 avlues, and copy it for all the scale.
This lisp use the block ename in argument.
We start to use that block with MLEADER, but we can not edited with our lisp (can not find the ename of the block in the MLEADER definition ).
Is that a way to find this ename, and to be able to modify (our substitute) all the attributes value.
