AutoCAD Visual LISP / AutoLISP :: Get Exploded Block Into A Selection Set
Feb 8, 2012
How to get the individual components of a block that has just been exploded within a lisp routine into a selection set. I want to alter the layer of each element to the insert layer of the block. I may also make one or two other changes according to what I find in the block.
I found a lisp to get block attribute data to a other block. See attachment. I can only apply it to one block. I like to apply it to selected blocks or blocks in a group. Is this possible?
I've created a lisp that draws the boltholes of a pipe flanges, using the correct number of holes, at the correct diameter at the correct bolt-hole diameter and then rotates. Everything works seamlessly, when i do just one flange. But I've discovered that fewuently there will be mulitple times when a user will have to perform the command.
So the idea I had was to do the following:
Select all circles with (setq CirclesFirst (ssget "X" (list (cons 0 "CIRCLE"))))
Go through the code to create the new circles.
Select all circles with (setq Circles (ssget "X" (list (cons 0 "CIRCLE"))))
Remove selection set "CirclesFirst" from "Circles".
But what for some reason (command "_.select" Circles "R" CirclesFirst "") does not work.
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'm trying to fix an issue with entlast where if the user hits escape during the process, the wrong entity gets erased, etc. Here's the problem code...
From a function that would have just inserted a dynamic block at 0,0 then modified it - here's where we pick up..
I'm putting together some quick function that I can send 2 arguments and get from it the total area of a given hatch on the given layer. I think everything is in order but I'm having trouble with the selection set filter:
(DEFUN GET-HATCH-AREA (HATCH LAYR / area sset) (COND((AND(ssget "X" '((0 . "HATCH") (2 . HATCH) (8 . LAYR))) (SETQ area 0) (VLAX-FOR H (SETQ sset (VLA-GET-ACTIVESELECTIONSET (VLA-GET-ACTIVEDOCUMENT (VLAX-GET-ACAD-OBJECT)))) (SETQ area (+ (VLA-GET-AREA h) area))) (ALERT(STRCAT "Total area = " (IF (OR (= (GETVAR "lunits") 3) (= (GETVAR "lunits") 4) ) (STRCAT (RTOS area 2) " sq. in. (" (RTOS (/ area 144) 2) " sq. ft.)") (RTOS area) ) ) ) (VLA-DELETE sset) ) ) ))
I can create an empty selection set (setq EMss (ssadd)). As I loop through a list I can use the counter to create selection sets on the fly by using:
(set (read (strcat "ss" (itoa cnt))) EMss) and even keep a list of the ssets created with (setq sslst (cons (strcat "ss" (itoa cnt)) sslst)). But when I try to add an ename to the ss with (ssadd ename (read (strcat "ss" (itoa cnt))), I get a error: bad argument type (SSADD NEXTE (READ (STRCAT "ss" (ITOA CNT)))).
why I can create the sets but not add to them this way? I can add to them from the command line.
I wrote a lisp program which creates a selection set using ssget. Then I use the bounding box commands to get the lowest point of that selection set. Now I want to move that selection set as a whole using the vla-move command. Can we vla-move a selection set?
To get the 'File Selection dialog box' in AutoCAD via LISP, which command should I use other than 'GETFILED' ?
I have a program which using GETFILED to select the drawing file , but I think this dialog box size is too small to browse folder/file , as you cant see the favorites list and you cant resize the dialog box.
I'm working on a lisp that goes through a whole list of files and does different things to those files. I've been racking my brain for a way to select just a folder via a dialogue box, but haven't found a way. I'm sure it can be done with dcl, but I don't know where to start.
This would not be the standard "file" selection box, but would only list the folders and let me select one even if there are others "under" them. This is what I'd like it to look like.
I'm not sure if there is a standard AutoCAD box that I could call for this or not
I have a lisp routine that creates a "frame wall" and I want to be able to automatically dimension said wall within the same routine. I have created two sets of points, each set being on its own new layer. I have made selection sets of each set of points, and want to cycle through each set dimensioning as required. This what I have so far for this part of the routine:
When I run the program I get the error: bad point argument. So what I think is happening is that the ssname command is not returning the actual value but just the name? I am new to AutoLisp and even newer to selection sets so be easy... Along with this, I am also curious as to how a selection set is ordered when it is chosen ie how does it determine what would be in (ssname sel1 0). Also, how would one go about deleting the points in these selection sets after the dimensioning has been completed.
Looking to make a selection set of points that are on a specific layer, and then create a dimension between, in this case, two points. I feel like it should be very simple, but I can't get it to work for the life of me. Here is the test code I've been playing around with:
when it comes to setting paperspace as the 410 ssget list value as the name can be modified and I need it to work in all drawings. I tried setting a variable to the paperspace layout name and using a print function at the (410 . "model") point but without sucess.
I wrote a lisp program which creates a selection set using ssget. Then I use the bounding box commands to get the lowest point of that selection set. Now I want to move that selection set as a whole using the vla-move command. I am having trouble doing this. Is this possible? Can we vla-move a selection set? Is there a workaround?
I downloaded a lisp routine that will align block attributes. The problem is I can only select the attributes one at a time. I'd like to be able select multiple attributes using the selection window or a crossing window, but I haven't had much luck. If you use the AEATTSHOW command, it give you a prompt to "select using window" by pressing W. I'd like to have the same functionality for my Align attributes routine.
Below is the portion of code I currently have to select attributes one at a time:
;* Select all attributes to align with the parent selected above and add the attribute entname and the block ;* entname to a list in format ( (AttrEntName BlkEntName) (AttrEntName BlkEntName) (AttrEntName BlkEntName) ) ;* while (/= TempAttr nil) (setq TempAttr (nentsel " Select Attributes to align: ")
What about creating an AutoLisp selection set from .NET - is it possible, if so I would prefer to do that instead?
The goal is to create some objects in .NET (using activeX or managed code) and then have some way to access these objects via the command line I'm assuming they only way is using an AutoLISP selection set.
and so on, but the example above caters for situations the users enter the values of 1, 2, or 3. If the user enters anything else I get a nil response from AutoCAD. So I devised the following
(if nil (alert "Wrong selection"))
but no response from AutoCAD qua an alert
also tried to be more in uniform with the rest of the lisp and wrote
I have some strings like the ones below. They are always in the same format. The first line is Cold Water, the second is Hot Water and the third is Hot Water Return.
I want to build a selection set based on whether it is CW, HWS or HWR. Right now I have a routine to retrieve the string by using ENTSEL. In other words if I want to use the line of text for Cold Water I have to select it.
I'd like to be able to window them all and filter the SS for only the string containing CW and conversly HWS and HWR. SSGET function filter.
