What Is Microsoft VBA Module for AutoCAD?

Microsoft VBA Module for AutoCAD is a powerful tool that allows users to automate and customize their AutoCAD drawings using the Visual Basic for Applications (VBA) programming language. With this module, you can create macros, add functionality to your drawings, and streamline your workflow.

What is VBA?

VBA stands for Visual Basic for Applications. It is a programming language developed by Microsoft that is embedded within various Microsoft applications, including AutoCAD. VBA allows users to write scripts and macros to automate tasks and add custom functionality to their software.

Why use VBA with AutoCAD?

AutoCAD is a versatile software used by architects, engineers, and designers for creating precise 2D and 3D drawings. While it has a wide range of built-in features, using VBA with AutoCAD opens up endless possibilities for customization and automation.

Benefits of using VBA with AutoCAD:

  • Automation: With VBA, you can automate repetitive tasks in AutoCAD, saving you time and effort. You can create scripts or macros to perform actions such as drawing objects, modifying properties, or generating reports.
  • Customization: VBA allows you to customize the AutoCAD interface by adding new commands or modifying existing ones. You can create your own toolbar buttons or menus to access frequently used functions.
  • Data manipulation: With VBA, you can extract data from your drawings or external sources and manipulate it to generate custom reports or perform complex calculations.

Getting started with VBA in AutoCAD

To start using VBA with AutoCAD, you need to have the Microsoft Office suite installed on your computer since it includes the necessary components for running VBA. Once you have the prerequisites, follow these steps:

Step 1: Enable VBA in AutoCAD

To enable VBA in AutoCAD, open the Options dialog by typing “OPTIONS” in the command line. In the Options dialog, go to the “System” tab and check the box that says “Enable VBA integration”. Click OK to save the changes.

Step 2: Accessing the VBA Editor

To access the VBA Editor in AutoCAD, type “VBAIDE” in the command line. This will open up the Visual Basic Editor window where you can write and edit your VBA code.

Step 3: Writing your first VBA program

Once you have opened the VBA Editor, you can start writing your first program. The basic structure of a VBA program consists of a Sub procedure, which is a block of code that performs a specific task.

Here’s an example of a simple VBA program that draws a rectangle:

Sub DrawRectangle()
    Dim acadApp As Object
    Dim acadDoc As Object
    Dim acadModelSpace As Object
    Dim rect As Object
    Set acadApp = GetObject(, "AutoCAD.Application")
    Set acadDoc = acadApp.ActiveDocument
    Set acadModelSpace = acadDoc.ModelSpace
    Set rect = acadModelSpace.AddRectangle(acadApp.Point(0, 0), 10, 5)
    acadDoc.Regen acAllViewports
End Sub

This program creates a rectangle with a width of 10 units and height of 5 units at coordinates (0,0) on the current drawing’s model space.

Select and run the program to see the rectangle being drawn in AutoCAD.


Microsoft VBA Module for AutoCAD is a powerful tool that allows users to extend the functionality of AutoCAD by automating tasks and customizing the software to suit their specific needs. With VBA, you can save time, increase productivity, and unlock the full potential of AutoCAD.
