Does Object Reactor has an owner size limitation?
when the owner size is big (about 1000) trying to disable the reactor (vlr-remove ReactorObj) causes AutoCAD to crash right on spot.
i am trying to add a reactor to ddatte command, would like to know which object was being edited, the ename or object name (ssget "P") does not seem to be the one
View 5 Replies View RelatedI use the following code to assign a reactor to an object.
Now I noticed that if I close the dwg file after you successfully saved, when I open even if I load the lisp, the reactor does not work.
Another problem: when I use the command "erase" or "explode" the reactor is started twice, why? you can run it at once?
(setq marReactor (vlr-object-reactor (list (vlax-ename->vla-object oggmar)) "TEST" '( (:vlr-erased . reactor_upd) (:vlr-modified . reactor_upd) ) ))
how can I check whether an object has a reactor connected?
I wrote the following
(defun c:**** (/ ogg collegaReactor) (setq ogg (car (entsel))) (setq collegaReactor (vlr-object-reactor (list (vlax-ename->vla-object ogg)) "NOMEAPP" '( (:vlr-modified . testedit) (:vlr-objectClosed . endedit) ) ) ))(defun testedit (notifier-object reactor-object parameter-list / ogg collegaReactor) (alert "testedit"))(defun endedit (notifier-object reactor-object parameter-list / ogg collegaReactor) (alert "endedit"))
If I start two or three or more times the "c:****" and select the same object, when I changethe "alert" appear several times.
I open the drawing without loading the function, when I modify an object with the reactors appears the following error message:
function definition: NAMEFUNCTION
You can avoid this annoying message without removing the persistent reactors?
I am using (trying to anyway) a :VLR-xrefSubcommandReloadItem reactor. My only question is how to get the xref/block name from the 'reactor callback data' Object ID.
I am ultimately trying to pass it to (vla-get-xrefdatabase ....), but I cannot figure out how to turn the second parameter from the reactor callback data into something I can use - for example the second parameter returned may be "65" or some other number.

It is possible to cancel a command using visual lisp reactors. If this is not there another way I could do that. I tried to use UNDEFINE but it works only with own CAD commands and not with Visual Lisp command.

(setq marReactor (vlr-object-reactor (list (vlax-ename->vla-object oggmar)) "TEST" '( (:vlr-erased . reactor_upd) (:vlr-modified . reactor_upd) ) ))
"reactor_upd" is the name of the function that starts every change or delete the object.
I would like to exclude the command "MOVE", ie if I move the object, I do not want that part to the"reactor_upd" function.
I have the following code to redefine a block after a command has ended:
(vl-load-com);*********************************************************(defun Redefine() (command "_.INSERT" "reactortest=reactortest" nil)(princ "Block redefined."));****************************************(vlr-command-reactor nil '((:vlr-commandEnded . endCommand)));******************************************************(defun endCommand (calling-reactor endcommandInfo / thecommandend) ; Get the name of the command.(setq thecommandend (nth 0 endcommandInfo)); Check name of the command.(cond ((= thecommandend "PLINE") (Redefine)));cond(princ));defun(princ)
It doesn't work because INSERT is an interactive function and can't be called while a reactor is active. Is there another way to redefine a block that can be used in a reactor? The block is in one of the default search path's.
I have created a very basic reactor as a test. As you can see, it doesn't actually do anything other than set a variable so I know the error isn't caused by something I'm doing with the reactor.
(defun np:test (reactor callbackdata / ) (setq abc 123))(if (not np:reactor1) (setq np:reactor1 (vlr-command-reactor nil '((:vlr-commandwillstart . np:test))) ))
OK, so the problem I have found is that if I load this reactor into a drawing and then use the MVSETUP command but escape out without completing the command, AutoCAD throws an error and becomes unusable. When I then close AutoCAD down I am met with multiple unhandled exception errors before the app finally closes.
I then altered the reactor from a vlr-command-reactor to a vlr-editor-reactor and found that with this, I am no longer met with the same error while escaping out of MVSETUP. However, when I close CAD down I am eventually left with an 'AutoCAD Application has stopped working' error dialog on screen which reports that acad.exe as crashed.
I am working on AutoCAD Architecture 2012 (although I have tried it on 2013 to with the same results) on Windows 7 64bit. I have also tried this on ACA2012 x32 and found the same error exists.
I am doing something fundamentally wrong in the way I am handling reactors?
I need to find a way to find a good replacement for "SAVE" command to use it within Reactor. I want to save A COPY of my current ("active") DWG document to another place *without making it current* (just like command "SAVE" does and did it always). I know I could use (vla-saveAs ...) to save it first to another Folder and then use (vla-save ...) to save it back to its current Folder, but there must be a way to do it simply and fast.

I tried for long hours, but without success. I tried to create a list of entities while the reactor is applied, but doing so need another reactor to change these entities after the first Reactor works.The codes I used are below:

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.

I need to get VLA-Object from block name.
here there is a code to get block name from VLA-Object:
(vlax-get-property obj (if (vlax-property-available-p obj 'EffectiveName) 'EffectiveName 'Name) )
but I need the inverse of this code exactly:
blockname(as a string)==>VLA-object
(defun GetVLA_BName (BName).......
so, how can I do it?
I am trying to write a simple (or at least I thought it was) code to flatten a 3d object into a 2d shape. For some reason after ACAD runs the lisp it recognizes the flatten command but it will not select all. this is what I have:
(defun c:fl () (command "flatten" "all") )
I have even tried the pick first command, to select all then run the flatten command but that still doesn't work.
I there any way to set the dimension break size in autolisp ?

View 2 Replies View RelatedI am looking for a lisp routine which will allow me to mirror an object that I pick automatically. I don't want to have to pick the two points to set the mirror line. I just want the point I pick on of the object I select to be the point of the mirror. If that can't happen, I was wondering if the object could mirror at its insertion point (like if it were a block or a text.
View 7 Replies View RelatedWe use multi-leader objects in our drawings. When the multi-leader and its value are to be replicated throughout the drawing, we create mleaders with fields that show the contents of the first mleader. That way we can update only the value in the first mleader and all of its children will update as well. It works nicely for us.
Here comes one snag. If one of us opens a drawing with which we are not intimately familiar, we don't know which mleader is the parent of which children. There might be fifty parents and four hundred children in a drawing so going through them by hand is a big productivity drain.
What I need to do is write a routine that will let the user select the mleader that includes the field and have the routine highlight and/or zoom to the parent object.
I thought I should be able to find that info in the dxf codes for the mleader, but I am either missing it or it's not there.
I am creating a line using entmake, but I need the start and end point to be variable that was already defined ex.

(29.2813 20.5 0.0)
Command: !line_end

What do I do to make it recognize this variable?
I have this lisp which will display the height of a 3D object to 2 dps. What I need is for 3dps to be displayed but I have no real understanding of LISP coidng so I can't work out where this is specified in the routine.
Why this LISP does not work when I try to use it in a drawing which has a Pointools POD file working (or previously had one) within it?
I want to change the arrow size in AutoCAD mechanical using Visual Lisp. (No other language is allowed by the company).
I have the code in VBA but I have not been able to generate equivalent Vlisp code.

Importing the library does not make any difference (but I think it is not necessary).

View 2 Replies View RelatedI had a drawing of 64 MB size.Eliminating the single element and no element groups and optimising the block design we could reduce the drawing to 48 MB size.The drawing does not have layer filters, states and is purged completely.

What else could be done to reduce the drawing size. The drawing response time is too slow as of now.

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...

(setq blks (vla-get-blocks odoc))

I've gotten these two routines from different threads on here. One works with *text and blocks. The second works with multileaders.
