If you want to take a stab at VBA programming in AutoCAD, you’ll need to install the Visual Basic Extension. If you’e not interested in programming AutoCAD in VB or VBA but do use AutoLISP, I’d encourage you to keep reading, this article is still for you. Microsoft kept it around and still today, Autodesk supports VBA, a version of Visual Basic embedded within the Application over half a decade later. It was however still available as a separate download for a limited time but that time never arrived. Net based languages so Autodesk pulled support in the shipping versions of AutoCAD years ago. This was supposed to fade away as Microsoft moved to the. Most people may think of this as Visual Basic (pre. Pretty much the same hey? In Part 2 we'll have a look at how we can access these Objects programatically.ActiveX is a framework developed by Microsoft in 1996 which adapts earlier concepts of COM (Component Object Model) and OLE (Object Linking and Embedding).

Now double click on :Ĭompare this list with what you see when you open the Options-Files Dialog : This is all the Objects within the AutoCAD - Application - Preferences object. This is a list of all the Objects within the AutoCAD Application Object. Double click on the "ACODBJECT" in the "Watch window to open the "Inspect" window : We are now looking at the Acad Application object. Now, double click on the variable "acadObject" in the Console window to select it, and then add it to the "Watch" window. Type this at the Console prompt and then press enter : _$ (setq acadObject (vlax-get-acad-object)) To establish this connection, we use the (vlax-get-acad-object) function. We are going to open the AutoCAD drawer to have a look at what is inside. The cabinet itself is your computer and one of the filing cabinet drawers is AutoCAD. If (vl-load-com) is not loaded, the application will fail."Īfter loading the Visual Lisp functions, the next step is to establish communication with the AutoCAD Application object. "All applications that use Visual Lisp should begin by calling (vl-load-com). If theįunctions are not loaded, (vl-load-com) loads them. Support is already loaded if so, the function does nothing. The (vl-load-com) function first checks if the VLisp

Type this at the Console prompt and then press enter : _$ (vl-load-com)ĭid you notice that nothing happened? Before you can use the VLispįunctions with AutoLisp, you need to load the supporting code that enables Lisp Editor as we can, and will, use the "Watch" and theĬlose the Editor window, leaving the "Console" window open, and Notepad just like AutoLisp if you wish, but I prefer to use the Visual OK, are you ready to start? Right, fire up AutoCAD with a blankĭrawing and open the Visual Lisp Editor. Don't worry, we'll correct all that in future For example, some of my terminology may not be technicallyĬorrect as I've tended to convert some things to layman terms for clarityĪnd ease of understanding.
