  1. Hello, I have two reactor and two problems in callback functions. I have inserted same princ to be evident where is the error. Outside (from CallBack func reactors) they works properly. It seems that some LISP function are not compatibile to work in callback func (vlax-ename->vla-object, vla-update). My callback func.: - AppendBkAreaLst - when I copy an object included in _AreaBkLst, must add the new one to reactors : execution broke on line :(setq obL(vlax-ename->vla-object(entlast))) : message> 1 <Entity name: 1edac8b6420>2 ;
  2. Hello! I'm performing a count in order to create a report from a dwg file. Counting functioncan be called at any time, but necessarily runs on close - when I also count the edit time. For that I'm using a reactor. That works fine. Prior to start the counting I'd like to overkill the whole drawing. That way it will not generate fake data due to duplicated objects. My code: (defun finalize ( / total_vector t_time) (setq doc (vla-get-activedocument (vlax-get-acad-object))) (vla-sendCommand doc "_.-overkill\r_all\r\r_done\r") (arxload "EDITTIME") (load
  3. Hi, I need use (command ".save" pth) in my reactor for automatic back up after 30 minutes. But I can not figure out how to write this in Visual LISP. I want save current unsaved dwg to new file, but current dwg has to remain unchanged and still be active. Method (vla-saveAs doc) makes new file but makes active just this new file and close the old one. (vla-save doc) saves only without creating new file. Following code is a part of commandEnded callback reactor: (defun GM:createBackUp (cmd / doc pth) (setq doc (vla-get-activedocument (vlax-get-acad-object))) (setq pth (s
  4. Hello, I have problem with command reactor. I want to dress up (add some blok, put viewport in specific layer) all new layouts created by command „layout“ with option „New“ or the „plus“ icon in layout list panel. How can I find out the event (new layout) is occured? And how can I get reference to this new layout? Any ideas? Command ended reactor to command "LAYOUT" fires everytime even the new layout is not created. Thanks for help and I'am sorry for my english Marek
  5. Hi All, I have just hit a wall with some code I am working on and wondered if anyone had seen a similar situation (and found a solution). I have written a .NET routine that I use to control which Ribbon Menu Tabs and Panels are visible based on arguments passed to the routine. This runs correctly in AutoCAD 2016 when I call it from the command line or from inside a lisp function or command. However when I call the .NET routine from a reactor it fails: Command: System.ArgumentNullException: Value cannot be null. Parameter name: key at System.Collections.Generic.Dictionary`2.Fi
  6. So I want to be able to set things inside functions when the command is called up in the command line. I tried using a command reactor. It works fine when it is outside of the function that I wanted for it to be activated but when I put it inside the function, it doesnt seem to be getting the values of the variables before the command is called up. so I have a simple function used for texting. (defun c:trec() (reactoron) (command "rectang") ) This is not the actual function I want to use in autocad but using this as my test. So this is my reactor which lives in reactoron.
  7. Hello, I am trying to get a LISP reactor to work whist a function is running. So my scenario is, is that I have I have a function that draws certain things in AutoCAD. While this function is running, I want to have my reactor activated, so it sets things and when the function is cancelled, the reactor will revert everything back to the way it was before I used the function in the command line. Right now, I have the function that draws stuff and a command Reactor. Can someone point me to the right direction on how to get the reactor to activate inside the function?

    Lisp Command Reactor

    I want a command reactor to be able to activate inside a function however I am not sure if command reactors work with a user defined command or function. For an example, I want to be able to get the reactor to work on some (defun c:drawsomething () ....) and I want it to look for when the command drawsomething is called up? Can someone please point me in the right direction.
  9. I wrote a sub-routine to update drawing borders. There is a command in CADWorx called IGO which creates isometric drawings. I wanted have this command call my function which updates the borders. But my code doesn't work. (defun c:igo ( / ) (setvar "cmdecho" 0) (command "igo") (setvar "cmdecho" 1) (runisoborderupdate) (princ) )
  10. Hi everyone! I just want to start by thanking you all, as most of the times I have an issue this forum is a great resource in which I find many answers without having to create a thread Since we use Acad 2014, some of my coworkers have started using viewbase style views. Since we have standards regarding lineweights, I've tried to find in vain a way to set the lineweight default values for the viewbase layers (MD_Annotation, MD_Hatching...) when CAD create them. Since i couldn't find any way to give them default values upon creation, my only option was to pre created on our templates a
  11. Hi CAD lovers, Is it possible to distinguish between drawn objects (created by commands like: LINE, CIRCLE, ARC, ...) and constructed objects (created by commands like: OFFSET, FILLET (with radius), Chamfer (with distance), COPY, MIRROR (retaining source objects), ...)? Any help greatly appreciated.
  12. Hi CADmates, as most of you know, CommandWillStart and CommandEnded are two reactors triggered just when a command called and a command ended. I am looking for a way to control OPEN command after selecting a drawing and before actually OPENing it. Is this mission possible? Any suggestions and help greatly appreciated.
  13. Hi, I recieve a number of drawings from outside the company. Not too suprissing they don't use that same printers, not to mention IT has a habit of changing print servers every couple of years. We have switched to using PC3 files which has helped some, but I'm still lef with a large set of legacy drawings that called for a physical printer. When AutoCAD start the print command for one of these drawings I get a message box that basicly says that the printer defined in the layout cannot be found and it is substituting the "None" printer. I don't know about you, but I would assume that
  14. Hi all, who knows a way to cancell a command via reactors Here is my code of traping event of starting commands. I want to prevent AutoCAD of continuing some commands, with no success: (VLR-Command-Reactor nil (list (cons :VLR-commandWillStart 'Reactor:commandWillStart ) ) ) (defun Reactor:commandWillStart (-calling-reactor- -info- / *cmdname*) (setq *cmdname* (read (car -info-))) (cond ((member *cmdname* '(STYLE DIMSTYLE DDIM )) [color=red][b](command); it doesn't work [/b][/color] ) (T (mapcar 'princ (list *cmdname* " will start."))) ) ) Any suggestio
  15. Hello every body, is it possibleto retain reactors attached to objects in dwg file, without running a program in subsequent sessions:unsure:?

    VLR-SysVar-Reactor Help

    All, I am looking for a way to create a reactor that changes a system variable back to specific variable when it is changed by a User or AutoCAD. Specifically i am talking about MLEADERSCALE, you might have noticed that if you have several styles and you switch between them your Mleaderscale resets to 1 or the specific scale set in the style. I set dimscale and mleaderscale the same and when that change happens mleaderscale ends up changing forcing me to reset the mleaderscale after each time the style is changed. I want to see the feasibility of using VLR-SysVar-Reactor and :VLR-s

    Clock.lsp

    Let me state from the outset that I realise that there isn't too much practicality in this application, and hence I consider it more of a novelty app for your amusement and enjoyment. I have seen a few similar programs that will create a clock interface and proceed to animate the interface using a while loop or similar coupled with a small increment. These programs are cool in themselves, but take priority over all other user actions and also tend to lock up the average PC with all the entity regeneration. However, the engine that powers my application utilises a reactor to upd
