AutoCAD Visual LISP / AutoLISP :: Get A Block Count Without Opening DWG Object DBX
Jan 29, 2013
I need to write some code to count blocks inserted on the drawing.... I want to count also dynamic blocks... most of the time dynamic blocks are anonymous... so I'd need to check the Effective Name.
This line gets the blocks in the block table...
... but how do I get the blocks actually inserted in the dwg?
(setq blks (vla-get-blocks odoc))
Will a regular lisp expressions (like below) work with ObjectDBX... (drawing file not open)?
(setq ss (ssget "X" (list (cons 0 "INSERT")(cons 2 "`*U*"))))
I am looking to modify a block count lisp, the lisp counts the blocks and displays them in the command line. I am looking to take that list and insert it in to a leader.
So it will prompt me to select blocks.
1st Point of leader 2nd point of leader
and would generate the block list in the leader annotation.
Lisp routine to count the number of dynamic blocks of a specific name ("FD") by windowing an area of the drawing. I have a routine that I've been using to accomplish this, but i don't understand why it doesn't count dynamic blocks.
Is this something that is possible? Basically I have an excel file with sample data that comes coded (red background for fail, Green for pass) Then we transfer that into halos on a DWG. got a routine to count the halos in a DWG. Now I was thinking it would be nice if it compared the number to the excel file to make sure no mistakes were made when placing the halos.
So as I mentioned I've seen rountines to read data in cells but none to count cells based on colour.
Is there a way to programatically set a visual style before a drawing actually opens?
We have some huge models and people seem to forget to change their visual styles back to 2D wireframe before saving and exiting drawings. Some models will crash on some workstations when trying to open in a rendered mode.
I found a lisp with a function that looked to set viewport visual styles. But it does not seem to be supported anymore. --> (vla-put-VisualStyle vport 1)
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.
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
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))
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.

I have a rather simple 3rd party custom object... I tried to get its bounding box but the coordinates that come back don't seem to relate at all to the object.
What I'd like are the coordinates of two nodes the object contains...
Is it possible to apply the autocad cursor in some why with the node object snap to get their coordinates?
Right now I'm working on a program that will go into a directory and it's subdirectories, collect a list of all the .dwg files in those directories, then apply certain changes to all of those .dwg files.
My problem is that none of these things works.
(command "open" (srtcat basedir (nth i file))) (command "open" (nth i fullfile)) (vl-cmdf "open" (strcat basedir (nth i file))) (vl-cmdf "open" (nth i fullfile))
Where "basedir" is the main directory (e.g. C:/...), file is the list of the dwg file names (e.g. mydrawing.dwg), fullfile is the list of the ull paths (e.g. C:/.../mydrawing.dwg)
I have tried using the filename with and without the .dwg extension with no luck.
I have this code set in (while ...) so that it will go through all the files in the list "file" or "fullfile" in sequence. The lisp will run without errors but will not open any of the files. When I look at the command line, I see that the lisp has put open on the command line like it has executed the command, but right below that, it says "Unkown command: C:/.../mydrawing.dwg" or "Unkown command: dwg" depending on which of the above code pieces I'm using.
how to open an dynamic block DWG using a script and not have the "This drawing contains authoring elements. Do you want to open in block editor" message?
I cannot seem to get rid of this message and everytime I have to manually say "No" and let the script run.
If I try the routine I get ; error: Automation Error. Error Decrypting Data.
If I open the drawing normally (that works) and save as a dxf, then open the dxf and save it again as a dwg the routine works. I use the routine for 5 seperate drawings that get updated every month and would rather have a routine that opens the drawings without the fiddle.
What i would like to do is have autocad do a zoom extents automatically when I open a dwg. Is there a lisp routine that I can run to do this? I use to have something that would do this but I started a new job and cant remember.
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 would like to select all instances of a block, and put a new block on top of them using the same properties (insertion, rotation) but am unsure how to do this
MyProblem: after I insert the block “NrPunct” in my drawing ,, I cannot modify "textHeight", when I edit the ATTDEF (or attribute) with the command “DDEDIT” . Why?
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.
