Note: ActiveX support in AutoLISP is limited to Windows only. For example, if an entity is moved that your application has attached a reactor to, your application will receive notification that the entity has moved. If you design it to do so, your application can react to this notification with appropriate actions, such as moving other entities associated with the one moved, or perhaps updating a text tag that records revision information on the altered drawing feature. A reactor communicates with your application by calling a function you have associated with the reactor. Such a function is referred to as a callback function. There is nothing particularly unusual about reactor callback functions—they are like other AutoLISP functions. Before you can use reactor, you must load the AutoLISP extension functions that allow you to create them.

Issue the following function call to load reactor support: vl-load-com All applications that use reactors—including all callback functions—should begin by calling vl-load-com. Topics in this section. There are many types of AutoCAD reactors; each reactor type responds to one or more AutoCAD events. Before you can add reactor functionality to your application, you first need to write a callback function that performs the tasks needed at the time of the reactor event. You create a reactor that links a callback function to an event.

AutoLISP does provide limited support for reactor callback functions executing in a document that is not active. You can list of all the reactors in a drawing with vlr-reactors and determine all the possible callback conditions for a specific reactor type using vlr-reaction-name.

There are two types of reactors that you can create: transient or persistent. When using reactors, you need to make sure your reactors follow a set of guidelines to make sure they do not produce unpredictable results for your application if the internal implementation of reactors changes.

AutoCAD Visual LISP / AutoLISP:: Renaming Xref Using Code Jun 18, 2013 This lsp was passed on to me from a colleague but he doesn't know where he got it. It does a useful procedure of placing each xref, residing in the drawing, to a unique layer. The layer name is derived from the xref name.

I would like to edit this to take only part of the xref name. This system I work with requires all files to have the job number as a prefix eg LE1399901Contours.dwg, so the xref name would be LE1299901Contours by default. I want to remove the first 10 characters to be left with 'XXref-Contours' layer name using this code. (defun dxf (i a) (cdr (assoc i a))) (defun c:lxr ( / ss cnt xrs en ed bn xp xbn ) (setq ss (ssget 'x' '((0.

'INSERT')))) (setq cnt 0) code. Similar Messages:. ADVERTISEMENT Jul 31, 2009 Is it possible to run a lisp which can extract all the xref names, make a layer with that name and then change the xref on the layer?

I have got a similar routine from earlier posts but it doesn't work if any xrefs inserted in paper space (works fine on model space). Could change this routine allowing to change the layer of xref in paper space too. (defun dxf (i a) (cdr (assoc i a))) (defun c:lxr ( ) (setq ss (ssget 'x' '((0. 'INSERT')))) Code. Oct 2, 2012 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.

Civil 3D 2011 Windows 7 x64 Oct 12, 2011 I have set up a master set of dwg. Files we use to create our construction documents. The files consist of a master file that xrefs base files. All of our files are named using the project # first. I have set up the master set using x's to replace the numbers. Here is how it works: XXXXXXXc.dwg (master file) relative path xref's the following files. XXXXXXXlw.dwg XXXXXXXvlw.dwg XXXXXXXeg XXXXXXXfg XXXXXXXtitleblock note: all of these files are saved in the same folder.

I am trying to find a way to keep the xref paths working when I copy the files to a project folder and rename the files using the actual job # insead of the x's as place holders. As it is now, when I change the drawing name the reference is lost and I have to manually change all of the xref paths in the xref manager. Is there a command, program, or lisp routine than can change the file names and update the paths automatically. Mar 20, 2013 I have a specific problem with renaming layouts. I found some similar lisps, but I just could not make them work.

In every layout I have following attributes. PROJECT: 306 PHASE: RD OBJECT: A0101 PART: EL DRAWING: 611 ZOOM: X REVISION: 01 I need to rename every each of layout using those attributes. Layout's name should look like that: '306rdA0101el611x01'. 'rd', 'el' and 'x' must be written using lowercase.

Aug 20, 2013 Modify the attached lisp I found in this forum to work using a different hatch pattern, scale and angle.

Jan 27, 2012 I am looking for some mleader customization.Basically looking for a mleader that will add an objects name(in my case an xref or block) in the text.

Attached is a picture of our current process. Nothing special.

Basically instead of typing in text we use the insert field. In the field dialog that opens we select 'object' under Field names, then under object the type button is pressed to select object(in my case and xref or block) then under property the 'Name' option is chosen.

This will insert the xref name in the multileader. This is not terribly hard but am curious if I can automate and save some steps. May 10, 2012 I can't seem to find the SYSVAR that controls insert to 0,0,0 instead of pick on screen.

I've been trying to figure out if I can write a lisp that will do one of the following: Give an alert if an xref is moved.Not allow an xref to be moved.Tell the user when they open a drawing that an xref is not at 0,0,0 insertion point. Nov 25, 2012 what i would like to do is rename (externally) and repath about 4-8 xrefs in a drawing set of about 100 drawings. You may ask why? It is because we are trying to establish a template set of drawings for a civil design office. And when we start a new project, copy over the drawings to the relevant project folder, change the project number, run the script across the drawings and go from there.
