I have a lisp that draws variety of entities such as lines, arcs, hatches, points, blocks, text etc. How can I make one single block containing all of them, i.e. one block that has all items drawn since the lisp was invoked.
View 8 RepliesI am modifying stuff in a dynamic block insert entity. There is no "endblk" entity at the end of these definitions and I need to cycle through every entity within the block definition. When it gets to the last entity, I get an error because you cannot entnext passed the last entity. There are 2 things:
1. How to retrieve the # of entities in a block without cycling through it.
Or
2. A quick lesson in the *error* function, I cannot figure out how to implement this. I basically want to to say:
(if (entnext myent)) returns a error, don't abort & continue on.
I have a series of blocks that I need to insert into a drawing, maybe 100-200 times and then change one of the 6 attributes by an increment of 1.
I've looked at some of the older posts and have not been able to do this. Is it possible to take the tag regerence, in this case OUTLET_REF and automatically add 1 to it when the symbol is inserted.
Can this be done using Diesel or with a bit of lisp?
Is there any way to make a block uniform scale using lisp? and also make a block drawing uniform scale?

View 2 Replies View RelatedI know through the block command you can write out a selection of entities to a single drawing.But what I am wondering is if it is possible to have two drawings open, and transfer data quickly between the two?
As an example as we are detailing an assembly we create a title block around a detail, put dimensions and notes on as needed and would then like that to be transfered into another drawing next to the previously transfered detail drawing.
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 am having nearly 1000 drawings where I need to change the title block in a new format.
I am stuck up in moving all the entities in cordinates 15,280 (upper point) and 205,55 (lower Point) to 275,294 (upper point and correspoing lower point.
I have 2 selection sets and I'm looking for a more elegant method of checking if both sets contain the exact same entities (note - the order of entities might be different).

I have redined AutoCAD's copy command alias to C, but to also do other things, like set a few important variables in the background. One of the lisps I've incororated are making new viewports, that also create layers that are visibly specific to the viewport being created.
We were tasked a while ago to do an easy job of copying entities (dimensions, text and what not) in a layout. The problem is, users are copying the viewports too, which is bit more ineffificent than using the create viewport command I developed.
Is there a way to see if a selection set includes (0 . "VIEWPORT") entities? If the check returns nil, well then all is good. If the check returns "true", then I can prompt the user that a "VIEWPORT" entity is selected. I can then exit the command, or ask the user if they are sure they want to copy the "VIEWPORT" entity.
I have code that will set and sae a current UCS to the front of an entity, of course, depending on the viewpoint. This is so, because we need all draft lines in front of 3D solids, such as dimensions, leaders for labels, text entities and so on (the reason for not putting these entities in paper space is another discussion ).
But I'll have on of two problems on numerous occasions:
1. The user forgets all together to run the command.
2. The user will pick the wrong entity that is in the foremost position in that view.
The code I have utilizes the following:
(setq ent (car (entsel)))
(vl-load-com)
(setq obj (vlax-ename->vla-object ent))
(vla-getboundingbox obj 'LowerCorner 'UpperCorner)
(setq LowerC (vlax-safearray->list LowerCorner))
(setq UpperC (vlax-safearray->list UpperCorner))
Then I'll analyze the X, Y and Z of both the lower and upper corners, and set my UCS to whatever is proper.
Is there a "LowerCorner" and an "UpperCorner" for all entities. I can't see "VSMIN" and VSMAX" working because the elevation of the returned coordinates is always "0,0"
I have a lisp routing that the user has to use, to create a ucs, that is exactly on the front of the entity the user selects, so that whne they are drafting, labeling, dimensioningn the 3D entity, none of the drating lines are hidden when plotted.
The code is as follows:
(setq obj (vlax-ename->vla-object ent))
(vla-getboundingbox obj 'LowerCorner 'UpperCorner)
(setq LowerC (vlax-safearray->list LowerCorner))
(setq UpperC (vlax-safearray->list UpperCorner))
[code]...
Then I do a condition to see which points are greater than others, and move the ucs depending on the view to the foremost point. The program works perfectly.... however, often, they forget to use it.
I was wondering if I could incorporate it in another lisp that everyone uses, but not having the user pick the entity they want to be in front of (sometimes they pick the wrong entity). Instead, take the group of entities (anywhere between 1 to 30 per drawing (these are piping spools, so the entity count is not that great in model space)) and set a front working plane in model space. Working in paperspace is not an option, we're just too deep into our templates and processes.
I know there is a vmin and vmax, but they are for the X and Y axis, a VMax along the Z-axis would be great.

I found a means to access the unnamed group, however I am having trouble creating the list.
Command: (entget (cdr (assoc 350 (dictsearch (namedobjdict) "ACAD_GROUP"))))((-1 . <Entity name: 7efe6280>) (0 . "GROUP") (5 . "130") (102 . "{ACAD_REACTORS")(330 . <Entity name: 7efe5c68>) (102 . "}") (330 . <Entity name: 7efe5c68>) (100 . "AcDbGroup") (300 . "") (70 . 1) (71 . 1) (340 . <Entity name: 7efe6268>) (340 . <Entity name: 7efe6260>))
In the example above, there are 2 entities in the group.
What I want to do is to remove a certain entity from the GROUP, then delete the entity.
Repeat until all entities of that type are removed (I can figure this part out...).
How do I create a Selection Set (or LIST) of all entities inside a GROUP?
To access the first GROUP name in the dictionary:
(cdr (assoc 3 (dictsearch (namedobjdict) "ACAD_GROUP")))
I am working on a flood inundation, I would like to find a lisp or command(i'm not finding) to connect two points with a given elevation following the surface file or surface entities.
here is a small section as example right now it's just guesswork, some of these have taken a week to connect all the sections.
I have a drawing with various layouts that when I do a Zoom Extents the drawings is reduced to the size of a point.
I have done all the usual, ie: look for extra entities that are "out in space" so to speak and there are none.
I wonder if I have a block or image which may have an insertion point "out in space" and if this may be the issue.
Is there some way to Select all entities or Blocks (insertion point) that may exist outside a particular area ie: drawing limits.
I want to edit 1 attribute value in a block to number all my blocks (eg A001, A002, A003...) (example picture attached)
I know about the at tout and at tin but I need a lsp routine that only changes one attribute value without having to double click and go through that.
i attached a lsp routine, how to edit and remove everything except the value part.
I'm creating the following macro:- (defun C:BK () (command "_BREAK" PAUSE "_F" PAUSE "@" )(princ)) to add to a shortcut key lisp file and then I want it to repeat... How do I make it repeat?
I want it to do the same as this:- *^C^C_break \_f @ but as a shortcut key in a lisp format.
When we launch the list command, the Area system variable holds the area value of the selected shape.
How to get the length value into an Autolisp program to use it?
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...

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 )
We have this need to have all of the solids in a drawing to be placed in the "solid" layer.
Sometimes folks are drafting lines to develop these solids, and keeping the lines on the "solid" layer, rather than moving them to another layer, or deleting them altogether.
I could get folks to run this command before leaving the drawing.
I'm thinking something along the lines of:
Select all entities that are on the solids layer that are not solids.
If nil, great, do nothing.
If entities are selected, let me do something with them.
I'm hoping the following can be modified ever so slightly.
(setq non_solid (ssget "X" (list (cons 0 "3DSOLID")(cons 8 "solid"))))
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.

Is there a way to apply a single string value "Phase1", or "Phase2" to all layers in a drawing? I though about exporting a Layer State, modifying it in Excel, then re-importing the layer state, but, Layer States don't store a value for "Description."
I'm creating a consolidated map from several drawings, but I'd like to be able to separate the layers from each drawing. Description seems like a good value to populate and be able to sort by in the Layer Manager.
Trying to get the files I use which are single-layout tab files to name the layout tab to match the file name, minus the .DWG extension.
