If you do a LIST command on a dynamic block... AutoCAD tells you the Block Name as well as the Anonymous Block name.
How can I use ssget to snag all Dynamic Blocks that use the 'Real 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?
I'm having an issue with using the SSGET to select a block so I can move it. I'm changing the UCS to be at the center of the top view in the program(user selects center) and the block is at 0,0,0 after changing the UCS. However when I use SSGET it doesn't select it. So I used:
(setq en(car (entsel "
Select a block :")))(setq enlist(entget en))
and it lists the DXF Code of 10 as
(10 15.0893 13.5165 0.0)
How can I then select it if I don't necessarily know where the block is going to be?

I've had a simple lisp I've been using for years that suddenly disappeared. It required that you identify a block name, tag name, and the value that you want the tag to be. All of this is performed via command line, so it is scriptable. Since I lost it, I've been experimenting with -attedit. This command comes frustratingly close to what I'm looking for, except it only appends an existing tag, or replaces a specific string within the tag; I can't get it to replace the entire tag, regardless of its value.
1> Any lisp routine that does what I describe?
or
2> How to make -attedit replace a tag value without regard to what the value currently is (like a * wildcard)?
I need to delete a specific block from current opened drawing by LISP command.
for example removing XREF attached is very easy:
(COMMAND "-XREF" "D" "FRAME")
I can remove "FRAME" XREF from drawing. Now, I want to delete a/all block with "TB12" name with same action!
(command "BlockDelete" "TB12")
so, how can I delete a/all block with specific name in current drawing?
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 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 have already searched the web and this newsgroup but have not found the solution.
I've been twigging around with a selectionset, but no luck. I need to build a ss with several named blocks and a few dynamic blocks which get selected as anonymous. Unfortunately not all dynamic blocks should be selected and I can find no way of either filtering out a list of dynamic blocks to exclude nor any way to campare to a list of dynamic blocks that I want selected. Below is the best idea that I had but if I wrap it into a foreach with an exclusion list, I get an empty selection set returned. (I'm guessing that I need to trim the pairs each iteration and only return the matches instead.)
(SETQ blklst (LIST "Cleaner" "DRAIN" "Return" "Therapy""PoolLight" "Paraleveler" "Waterleveler" "Skimmer" "UMSLEEVE") blst "Cleaner, DRAIN, Return, Therapy,PoolLight,Paraleveler,Waterleveler,Skimmer,UMSLEEVE")(IF (AND (SETQ ss (SSGET "x" (LIST '(0 . "INSERT") (CONS 2 (STRCAT "`*U*" blst)) '(410 . "Model")))) (FOREACH i blklst (MAPCAR '(LAMBDA (x)(IF (NOT (EQ i (VLA-GET-EFFECTIVENAME (VLAX-ENAME->VLA-OBJECT (CADR x)))))(SSDEL (CADR x) ss) ) ) (SSNAMEX ss)) ) ) (WHILE (SETQ Ent (SSNAME ss 0)) (SETQ BlkName (CDR (ASSOC 2 (ENTGET Ent)))) (IF(SETQ tempList (ASSOC BlkName EndList)) (SETQ EndList (SUBST (CONS BlkName (1+ (CDR tempList))) tempList EndList))(SETQ EndList (CONS (CONS BlkName 1) EndList)) ) (SSDEL Ent ss) ))
The other code is long and I'd rather not confuse things; if I do not try to filter out any Unames, then everything works great and fast. Once I add in the "foreach i blklst" the code breaks and I get:
; error: null interface pointer: #<VLA-OBJECT 0000000000000000>
returned.
I try to use the SSGET function, and it returnes a string.
How to access the data?
Which function to use?
I wonder if I have to check if the "ssget" is empty.
I have a lisp to zoom extents in visible objects on the screen.
My interest is to filter before applying:If I have selected objects, it zooms in these objects. If I'm not have selected objects, continue as it is today, applying a zoom in the visible scene.
The result would be similar to a zoom of "3dsmax" (press the Z key)
The atual code
(defun c:ZOBJECTS(/ selectprev)(SETQ selectprev (SSGET "_P"))(command "._UCS" "View")(command "._zoom" "extents")(command ".__zoom" "object" "cross" "-1e99,-1e99" "1e99,1e99" "")(command "._UCS" "previous")(command "._select" selectprev ""))
Basically I want a dynamic block that works like an MLeader. I have built the block and can manipulate parameters, but haven't found a way to select a specific dynamic block grip.
It has a base point but then after placing the block I want to activate the stretch grip.
Is it possible to create a dynamic block completely from scratch using Lisp?
I also want the ability to be able to create different dynamic block geometry depeding on the Visibility parameter.
I seem to be able to create the normal (non-dynamic) block geometry using Lisp but cannot seem to find out a way to enter the block editor and create stuff pertaining to dynamic blocks.
I have 1000's of dynamic blocs to create and looking to a way to automate this using Lisp.
I have successfully created accessible parking dynamic blocks. They work fine for new parking because they are set to always be a certain width. 5'-0" or 8'-0" for an access aisle, etc. What i would like to figure out is how to create an existing access aisle that can be stretched horizontally & vertically.
The problem is that when the striping is at an angle as is the case with the access aisle how do i go about doing this? Could i put some sort of geometric constraint to be able to stretch it horizontally & vertically & keep the striping at a given angle. Also the striping may need to array as it is stretched.
Attached is a lisp that reads an attribute block value and uses that value to set a named view. The attribute block is a diesel expression field which reads the drawing number, so it changes as the drawing is saved to a new number. I use it when I am preparing road alignment drawings. I prepare the first drawing in the set, saving views for all drawings and when I'm done I copy that drawing 001 as many time as I need, rename them drawing 002, drawing 003 etc. and use the attached lisp with scriptpro to set all my saved views.
I also have a dynamic block called "key" in the drawing with visibility states matching the named views.
either expand this lisp or create a new lisp to set the visibility using the "VN" variable.
i am trying to select a dynamic block by its name but it does not work
(setq WW (ssget "x" (list (cons 2 "WET WELL"))))
We currently have a bunch of Lisp programs to create drawings but I am interested in exploring how I can maybe use Lisp with either dynamic blocks or parametric drawings. I just don't know which would make more sense. Currently we have programs where we enter things like width, height, leg or radius, bars wide and high etc and it creates a drawing like the one I've attached. I know that if I can create this drawing as a dynamic block or a parametric drawing, then when there are revisions, I don't need to create the drawing again. I can just adjust the parameter or the dynamic block. What makes the most sense, a dynamic block or a parametric drawing? I should note that I'd still like to use autolisp to create the initial drawing (or insert the block) since that's what the users are used to.
View 9 Replies View RelatedI figured out how to entmake a Block with attributes based on user input for insert point, rotation, etc.
My block is a detail bubble that is a circle with a tail, that cuts the object and shows direction of cut. I will include that with this post.
My problem lies in this. I've used dynamic block features such as linear for the tail length, and the cut length, and angle for the direction of the tail.
My old routine was simple, it would ask for detail point and angle. From that it would insert a block that was just the bubble and draw the tail and cut with a polyline.
Since then I've been able to use entmake, which is a lot more powerful for creating entities in AutoCAD. But for the life of me I can't figure out how to add the dynamic properties of my "new" detail block that has the tail, cut and bubble in one.
what I need in the entmake statement to make this create programmatically instead of inserting the block, then modifying it, if possible.
Is there any way to isolate an item in a list for a filter? I'm setting a filter for SSGET and know that I can use the dotted pairs and I know I can use logical comparisions but what I really want to do is filter a single varialbe in the DXF group 10. For example, I'd like to only get entities with a specific Z value in DXF 10. Or even better to filter for a specified range of Y value or X value in DXF 10. If I could write something like (cons 10 (list * * 8.0)) where the asterisks were wild cards, that would do it but I'm not aware of such a wildcard. Is there any way to isolate a portion of DXF 10 in the filter?
View 4 Replies View RelatedI 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.

I have this code that I wrote years ago that I want to update to select two types of civil3d objects and show them selected with grips on the screen. This function works fine
(defun CELFEATURE ()
(ssget "_X" '((0 . "AECC_FEATURE_LINE")))
(setq sset (ssget "P"))
(if sset
(progn
(sssetfirst sset sset)
;(command "_.PROPERTIES")
)
)
)
(defun cF () (CELFEATURE))
but if I add the extra object like this which I assume is the wrong syntax i only get the second type of objects. Need correct syntax I should be using for selecting more than one object in an ssget statement.
(defun CELFEATURE ()
(ssget "_X" '((0 . "AECC_FEATURE_LINE","AECC_AUTO_CORRIDOR_FEATURE_LINE")))
(setq sset (ssget "P"))

Distinctions between AutoLISP functions ssget and C# PromptSelectionOption method.AutoLISP ssget function is apply a function with no options and does not require an object selection.pre-selected target object should respond to the selection set.
However, and C# PromptSelectionOption, ignoring the pre-selected objects, select the new object is required.using the features of C# Prompt Selection Option expressed AutoLISP ssget do the same in,
I have a data structure called LayerList in the format [LIST "LayerName" "Linetype" Thickness Color]I then use the following piece of code to go through the structure selecting polylines and converting all polylines on a given layer to the correct thickness

(command "pedit" "m" ss "" "w" 0.15 "")

No polylines exist!")
)

However all i keep getting is Bad SSGET list value at the command line,
I have a new project coming up where I need to write some simple programs to access the dynamic action parameters in some existing dynamic blocks.I have viewed what I could find on AU, but I still ave not found anything relating in-depth to dynamic blocks.
Any good Tutorials, Articles, or White Papers, on working with dynamic blocks with autolisp/ vlisp? The main function is to access a parameter and change it by entering a numeric value, updating the block. say from a linear/polar stretch, or a linear/ polar move.
I've spent the last week and a half creating blocks that have between 2 and 10 visibility states in order to represent the separate iterations of common valves.
I would like to construct a lsp and dcl (we work off of a network drive that would enable a stable location for an accompanying dcl file along with the base lsp, though I believe that in order to do what I'm wanting done some on-the-fly dcl manipulation may be necessary) that would display the current drawings in our dynamic block folder and upon selection within the first List_box, would display the different options for visibility states for the block in the 2nd list_box. After a user selects one of the visibility iterations that are now displayed in the 2nd list, an image preview (or slide, I can handle creating the different slides for each block once if required) of how the block will be displayed in the selected visibility state would be shown in what would be the 3rd space, this time an image preview and not a list_box, though I would like proportionality between the list_boxs and the image preview. Some white space is allowable in the list_boxes.
I'm not even sure if this would be possible, but I'm assuming you can access the different visibility states in the same manner that you could access polyline verticies or block definition attributes.
When scanning the BTR (Block Table Records) and encounter a "*U" block definition
how can i know if it relate to dynamic block and have it's name?
acutally my current goal is:
when insert a dynamic block at default state (no change in it's dynamic properties/actions)
it's 'Name and 'EffectiveName is equal, when set some of it's properties it turns to dynamic anonymous
with Name = "*Unn"
Can i programaticlly set the block reference to be dynamic anonymous (with out setting any of it's properties)
cause i would like to modify it's BTR (with out effecting the original BTR dynamic block) but do not want to convert it to static anonymous block.
I 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 task where I need to automatically insert the drawing number (no path), plus two additional items, one an attribute, the other is within a dynamic block. I can achieve this using fields but now I havce to truncate some of the text.
It seems like I can't edit if I am using fields and attributes/blocks can't be used in Diesel (correct me if I'm wrong)
This is the information I have:
Filename: 123456-AS-WE.dwg
Attribute: Q2
Dynamic Block: X1 - Additional Information
This is what I require: 123456-AS-WE [Q2] [X1]
This is what I have so far: 123456-AS-WE [Q2] [X1 - Additional Information]
In other words, I need to restrict the dynamic block field to the first two characters.
I currently insert certain dynamic block into drawings with a short function that first inserts the specified dynamic block and then immediately changes the visibility state to one specified as an argument to the function.
I'm wondering if it is possible / better / faster to somehow insert the dynamic block with the decided visibility state simultaneously. I've been amazed by many capabilities of VL so I wouldn't at be surprised if this can be done. (the dynamic blocks I'm inserting could have many multiples in the drawing but I need this method to only affect the one being inserted at the time the function is called. I currently use entlast to decide which one is being inserted.)
I have a dynamic block that I would like to insert via a lisp routine. When the routine is run from my menu I would like to select two points on the drawing area. Then I would like my dynamic block to be inserted at one of the points I selected and then I would like a specific "point" of my block to be stretched to the other point that I selected. I was wondering if this is possible with LISP? I have my old LISP program I wrote that draws a leader and then inserts my block but that was before I started working with dynamic blocks.
Here is my current
(defun c:wldsym()
(setq osnapold (getvar "osmode"))
(setq orthold (getvar "orthomode"))
(setq dimsc (getvar "dimscale"))

wld1r.dwg is my current block. It has some dynamic properties already. But I'm trying to add new properties that can be seen in my working test drawing wld1r-new.dwg
When using my code with "wld1r.dwg" you can see how everything behaves right now. Then open "wld1r-new.dwg" and note that the insertion point and a stretch point my default are in the same spot. Work with the two stretch points and look at how the block reacts.
lisp to count dynamic block including total length.
