Visual Lisp Autocad 2. The vlax-reg-app function is more general and can be used to register any application. At the end of the file, you will find sample code that passes correct parameters to the register-VL-app function. This sample file provides an example of what can be accomplished with Visual LISP registry functions. The dump-registered-apps function prints out a registry database subtree for every application that is registered for demand loading in your AutoCAD Release 14 configuration.

One particular expression worth mentioning in the registry-tree-dump function called by dump-registered-apps is the second occurrence of the foreach function which contains a recursive call to registry-tree-dump. For each application that is registered for demand loading, there are three subkeys: Commands, Loader, and Name. This particular foreach expression applies the registry-tree-dump function to the string concatenation of each these three subkeys with the key for each of the registered applications to build and print out its subtree.

It is also important to notice that the vl-acad-defun expressions appear outside of the defined functions. If they were inside a non-command line function no "c:" , it would be impossible to call either of the two functions in sym-exp. Therefore, there are two rules to follow for explicitly exporting functions from an ARX routine without using a command line function to evaluate vl-acad-defun expressions :.

Code is included at the end of the sample file which can be used to test these functions from the AutoCAD command line. This program utilizes Editor Reactors to update a "time-stamp" text entity each time the user completes an instance of the PLOT command.

Between the user pressing OK to begin the plotting procedure and AutoCAD spooling to the plotter, the Editor Reactor fires off the callback function which adds or updates a time-stamp text entity at a base point of 0,0,0. The result is that until you run the Unregister-Timestamp function, the associated ARX application will automatically be launched the next time you start AutoCAD regardless of the drawing file that you open. Furthermore, if you open the drawing in which you registered the Time-Stamp routine without the associated ARX loaded, you will receive a notification dialog informing you that the required ARX application is missing.

To return to other commands for demand loading of vlide. There is a workaround contained in this sample file which solves an "Object Open for Read" error which you may receive in connection with associating a callback function with the PLOT command to modify a graphical entity.

The workaround is to add an additional graphical object to the drawing after creating the object which the callback function modifies. Upon loading this sample file, it uses ActiveX function calls to draw a line.

It then passes the line as a VLA Object along with a 4 x 4 transformation matrix to the vla-TransformBy function in order to rotate the line by 90 degrees. The file provides a total of five different matrices which can be used to rotate, move, or scale the line.

To switch to a different matrix, change the variable called in the vla-TransformBy expression. The use of matrices can be an excellent shortcut for manipulating graphical objects. Once created, the code for a matrix can easily be reapplied in other functions. The first three columns of the matrix specify scaling and rotation. The fourth column is a translation vector.

The functions that use a matrix of this type treat a point as a column vector of dimension 4. The point is expressed in homogeneous coordinates, where the fourth element of the point vector is a scale factor that is normally set to 1. The final row of the matrix, the vector [M30 M31 M32 M33], has the nominal value of [0 0 0 1]; it is currently ignored by the functions that use this matrix format. Its old Acad , but not that much has changed. Notice: updates available for Apache Log4j vulnerabilities.

You will learn how to create a drawingroutine that automates the generation of a complexshape—the kind of drafting operation you do not wantto draw over and over again, if it means starting fromscratch each time. It also assumes youunderstand basic Windows file management tasks such as creating directories, copying files, and navigating through the file system on your harddisk or network.

This environmentprovides you with editing, debugging, and other tools specific to the creation of AutoLISP applications. The tutorial has been thoroughly redesigned. Even if you are familiar withthe previous version, you will encounter entirely different source codeand a much more extensive tutorial. There are two possible execution contexts for the Garden Path tutorial. A VLX operates from a self-contained namespace that can interactwith the application-loading document.
