AutoCAD Visual LISP / AutoLISP :: Create Blocks And Name Them In Sequence?
Jul 13, 2012
i have created an Autolisp routine that creates a drawing made up of structural members, x-refs & surfaces based on a few different user inputs. I now want the program to insert the drawing as a block rather than individual elements. My Idea was simply to use the block command in the lisp routine to create a block and then have the drawing create itself in block editor, and close once it has done. however I am having difficulty thinking of a way that I can get AutoCAD to automatically name this block depending on other blocks in the drawing, i.e. in sequence. The name is irrelevent really, but it would make sence for it to be logical, so... if the last block inserted was "b7" then the next one should be "b8" and so on.
Is there a better way of doing it all together? I have read a bit into "entmake" but i'm not sure on how to use that function.

Any routine that will allow to draw a polyline through existing blocks, in the order the blocks should be numbered? Therefore when the sequence has been specified by the polyline then user to define the number system required, and the blocks are automatically numbered in the sequence of the polyine start to finish.

who can share with me a lisp which can create layer by xrefs and blocks ( if this can be an optional , would be nice ) ?
even maybe lisp can create layer group filter with "XREF" group name and move layers to inside.

i am trying to restrict users from modifying certain attributes in a block,i can create the blocks with some of the attributes on locked layers, but then autocad pops up an annoying alert box, is there a way to disable this? the other option i can think of is to redefine the commands *ddedit, *attedit, *ddatte,*attipedit,

I am looking for a way to create a master list of construction notes then use blocks attributes with fields to link to that master list. That way if the master list changed the note bubbles would change as well.
Sheet sets are being used with this project but I can't think of a way to make it work with the existing sheet set technology.

how to write a LISP that enable me to direct automatic rename multiple block name?
Example is i have 3 block names as " A123 " , " A728 " , " A003 "
When i activate the LISP, it will automatic rename the block name to be " CAD1" , "CAD2" & "CAD3", whereby
the word "CAD" i can change whenever i start to use it change multipld block name.

I have a project in 3D that I would like to export to Stadd. This requires lines rather than blocks. Is is possible to convert the blocks in the attached dwg file to to lines that are centered on those blocks?

I have an opportunity to make a good impression at a new job, but ive never had the initiative to learn how to write a lisp routine. at my work we make walk-in coolers and freezers. these coolers are modular with a standard wall piece measuring a certain length. these wall sections have to be numbered sequentially. is there any way to automate this? sometimes we get change order from the client and it means going back and manually changing multiple texts (sometimes in the hundreds), but i thought if there was a way these wall sections could be scheduled somehow that when a new wall panel is inserted in the beginning of the sequence it would update everything after it automatically.

I was on an older cad and am now moving to 2014.. my previous cad was heavily customized the old school way, I have decided to learn the CUI (and dynamic blocks)
My old cad has blocks on a drop down menu.. click BATH menu than WC icon, a macro sets the correct layer than inserts the WC.. took time to setup but pretty simple and straight forward (see attached for menu syntax). I also made a toolbar BATH and on that toolbar I made a WC icon.. that’s what I use the most
couple of questions
1) do I have to make a new command in CUI for each block to do the same thing?
2) I looked into the design center, but seems like its too many steps but it seems a toolbar with an icon on it, clicking the icon and a macro sets layer and insert block is still pretty quick..??
3) if a toolbar with an icon is still a fast and less step method, can I open the block and somehow make an icon of it? if so where do I put it?

I have this code w/ which I can open up Block Library Blocks for editing. We have R2012 installed w/out VBA.Our MIS department is impossible to deal with. We have this new fangled permission hysteria so I cannot install VBA myself.Is there any other way to open up my blocks? What I can I do instead?
(defun CpL () (prompt "...Open Library Block or Xref...")(terpri)
(setq a (entsel)) (setq b (car a )) (setq c (entget b)) (setq d (assoc 2 c))
(setq e (cdr d)) (setq ff (strcat e ".dwg")) (setq PP (findfile FF))
(setq opath (strcat "acadapplication.documents.open ""PP"""))
(command "vbastmt" opath))

My drawing constitutes of many blocks and other objects , and i need to find specific blocks (with same block name) in my drawing which i cannot find them one by one and i though that i can find them all with lisp routine ..
so , i wanna specify point out of my drawing area and lisp routine will draw to line from basepoint of those blocks to specify point when i select one reference block.

We've recently converted all our microstation drawings to autocad now that the company has decided to go with one cad program company wide.
One of the issues we are having after getting the drawings back from the this co. converting them is the cells to blocks convertion inside the drawing. when we open a drawing and see a "Fuse" block for instance and if it a has multiple inserts, it named them:
Fuse
Fuse_1
Fuse_2 etc....
is there a lisp routine or some command that would replace the "Fuse_*" blocks with "Fuse"..I've been searching the forums and know about the express tool Replace Block but need to be able to automate somehow.
I thought about trying to rename each of the "Fuse_*" but of course it won't let you rename to a block name that already exists..

would like to set a base point during insertion of one block.When not insert by AutoLISP, just type "b" to be able to change the base point.
But when I'm using an AutoLISP that inserts a block, it does not work, it interrupts the sequence of routine.
Lisp:
(defun c:carrobox()(setq #clayer (getvar "clayer")) (if (= unidades nil)(setq unidades "cm")).....

I wanted to flatten arcs, circles and lines inside a block using the following lisp (which I found in this forum). I found that sometimes this lisp is unable to flatten the ARCs inside the blocks. I do not understand why it is not working for all the blocks. I have attached a drawing in which this lisp is not working.
(defun c:FlattenRaj ( / blocks stpt enpt inspt )
(vl-load-com)
(setq blocks
(vla-get-blocks
(vla-get-activedocument

I'm using the attached lisp to change the parameters of a dynamic block. In particular, I use the function chgdynprop
(defun c: test () (setq oggfreccia (car (entsel))) (chgdynprop (Vlax-ename-> vla-object oggfreccia) "Distanze1"300.0))
The lisp function works properly, because if I select the block from the bar I can see that property Distanze1 = 300.0

I am looking for a routine that will replace all blocks named "DgnMisc_nodepoleind" with a block named "DgnMisc_nodepoleind2" keeping the insertion point. I could use (command "-insert" "DgnMisc_nodepoleind=Y:/ACAD2007/DA settings/Library_new_scale1/DgnMisc_nodepoleind2.dwg" NIL ) but my problem is that the block I want to replace is used on two different layers and I only want to replace the ones on layer "TPSYM01".

I want to find a Lisp routine for building rooms (bedroom, bath, kitchen etc). example: I want to build a bedroom and every bedroom has the following blocks: smoke detector, door, window, bed, night stand, closet. Is there a way to run a lisp routine that would just ask me for basepoints and rotation angles of all those blocks? Basically it would automate building a bedroom by inserting all the blocks for me and just prompting me for basepoints + rotation angles.
Would a macro be better suited for this? I want to do one for every room - kitchen, bath, bedroom, living, dinning etc. I already have a nice collection of blocks.

I'd like to use AutoLisp to modify and in some cases replace existing dynamic blocks in a drawing. How can I retrieve existing values and then modify values for the following:
1. Visibility states
2. Distances
3. Rotation angles
4. Flip states

I have an XREF that contain block inserts sometimes nested 2 or 3 levels deep. Given the block names, is it possible to find and translate the insertion point of the nested inserts to the current World UCS?
Ideally I would give a routine the block name and it would scan the current drawing and return a list of the translated insertionpoints>

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.

I want to explode all anonymous blocks, but how do I create a selection set of them.?(ssget "x" '((2 . "*U*"))) doesn't work, and is dangerous if you have any blocks with the letter 'u' in them.

I need a function that will allow me to do a "divide" with blocks but I need the single attribute to remain intact.
I need the blocks to align with object and keep the attribute. I did get it to work with constants but the function that I need to run next failed because of the constant. My variable is preset and locked.

I have 30 blocks per drawing about 60 drawings. Each block starts with the jobname has other block info and then the block type. For example
Bldg31-MechEquip_ABC
Bldg33-MechText_DEF
Bldg45-ElecEquip_GHI
I want the output to be just ABC, DEF, and GHI.
I have a rename script but I dont know where to go from here. How can I tell it to remove everything up and including the "_" symbol?

I want to code this lisp. The problem which I face is, In some drawings which come from the client, there are a lot of blocks.
I want to detect the blocks which has no sub-entities (but attribute) and add a rectangle inside this block, If it is an attribute add a line from 0,0, to insertpoint of attribute.

I wonder if it is possible to have a routine that captures the visibility name of a dynamic block and place it in a text in the drawing?
For example, I have a block with 10 visibilities. I copied this block 10 times in the project and I put each one with a different visibility. Now I would like to make a label with the name of each visible state next to each block.

1) I want to search the drawing for the pre-define block names given in the program.
2) If the are there, I want to replace them with the new version.
3) Program replaces the first block it finds, then tries to insert that block.

I would like to batch rename all blocks in a drawing to NEWJOB01, NEWJOB02 ,etc. I can't use wildcards with RENAME command because the old names don't always have a common name. I prefer to use a lisp routine.

The code below collects empty blocks with the intent to delete them.However, it appears that if an Xref is currently 'unloaded' it apparrently collects that too. I could probably just test to see if the block is an Xref and avoid it... but how could I modify this to check if it is loaded and still empty?
(defun NullBlocks (/ block *thisdwg* block nullblocks)
(setq *thisdwg* (vla-get-activedocument (vlax-get-acad-object)))
(vlax-for block (vla-get-blocks *thisdwg*) ;iterate block table
(vla-get-Name block)
(if (= 0 (vla-get-count block))
(setq nullblocks (cons (vla-get-name block) nullblocks))
)
)
nullblocks
)
