What is a VLX file?
A VLX file is a compiled application used by Autodesk AutoCAD, a computer-aided design (CAD) application, to extend its functionality using the AutoLISP and Visual LISP programming languages. It contains compiled AutoLISP routines and can package multiple source files and other resources into a single application that AutoCAD can load and run.
More Information
VLX files are similar to .FAS files, which also contain compiled AutoLISP code, but a VLX file can package multiple components together as a single Visual LISP application. Developers can create VLX files by compiling AutoLISP or Visual LISP source code with the Visual LISP development tools included with AutoCAD. Packaging code as a VLX file can make it easier to distribute and load an application containing multiple routines.
VLX files are primarily used by AutoCAD developers and CAD professionals who create or use custom tools to automate repetitive drafting and design tasks or add features to AutoCAD. Since the files contain compiled code rather than the original source code, users generally cannot edit the routines directly as they would an .LSP source file. Developers who need to modify a VLX application typically work from its original source code and compile it again.
How to open a VLX file
You can open VLX files with Autodesk AutoCAD, which is the primary program for working with these files. To use the file, load it in AutoCAD with the APPLOAD command, which compiles the program in your AutoCAD environment.
