Add Text In AutoCAD Using Excel VBA


The previous week I published a VBA code for drawing circles in AutoCAD using data from an Excel workbook. Since I received several email requests from various blog readers, I decided to continue the subject of AutoCAD automation from Excel. So, below you will find a VBA code that will help you “send” text strings from Excel to a specific location in an AutoCAD drawing. The code might be extremely useful for filling the information in a drawing legend (watch the demonstration video for example).

The code is based on the AddText method. According to AutoCAD VBA help, the structure of this method is the following:

RetVal = object.AddText(TextString, InsertionPoint, Height)

RetVal: Text object. The newly created Text object.
Object: ModelSpace Collection, PaperSpace Collection, Block – the objects this method applies to.
TextString: String; input-only. The actual text to be displayed.
InsertionPoint: Variant (three-element array of doubles); input-only. The 3D WCS coordinates on the drawing where the text is placed.
Height: Double; input-only. The height of the text. It must be a positive number.

The sample workbook that you will find in the Downloads section below requires three main user inputs (as the AddText method), as well as four optional: the coordinates of the insertion point (in X, Y, Z) – in other words, where you want the newly created text to be inserted, the text height (like font size) and the text message that should be displayed in the drawing. Then, by clicking the “Add Text” button the text is inserted either in the active drawing (if AutoCAD is already lunched), or in a newly created drawing. The optional parameters give additional functionality, so you can adjust the alignment, the rotation angle, the width factor and the color of the text to be inserted.


VBA code to add text in AutoCAD from Excel

Similar to the circle case, almost half of the code is used to initialize the AutoCAD object, as well as the active/new drawing object.

Option Explicit
Sub AddText()
    'This macro adds text in AutoCAD using data - insertion point, text height and text message - from Excel.
    'Moreover, it provides some optional parameters, so that the user can adjust the alignment, the rotation angle,
    'the width factor and the color of the text to be inserted (using the Red, Green and Blue parameters).
    'The code uses late binding, so no reference to external AutoCAD (type) library is required.
    'It goes without saying that AutoCAD must be installed at your computer before running this code.

    Set acadDoc = Nothing
    Set acadApp = Nothing
    'Inform the user about the process.
    MsgBox "The text was successfully added in AutoCAD!", vbInformation, "Finished"
End Sub 

Note that if you have AutoCAD 2010 or a newer version, you will have to download and install the VBA module, otherwise the code will probably fail.

Demonstration video

The short video below demonstrates the result of the above VBA code. Seven lines of text are inserted in the legend of this sample drawing. Each line has a different color, scale factor, and alignment, while the rotation angle for all lines was set to zero.




The file can be opened with Excel 2007 or newer. Please enable macros before using it.

Hi, I am Christos, a Mechanical Engineer by profession (Ph.D.) and a Software Developer by obsession (10+ years of experience)! I founded this site back in 2011 intending to provide solutions to various engineering and programming problems.

  • Hi, Jayagurunathan,

    The functionality to edit attributes is something that I have postponed for quite a while (I am working on it).
    I will release it at some point but as a commercial workbook/add-in).
    It’s not as straightforward as this code.

    Best Regards,

  • Hello Christos, I m jayaguru from india. Thanks for sharing the XLS and your site also looks good … Its great learning for me… Can u help me to improve my idea ? The idea is to insert blocks with attributes in autocad by using excel VBA

  • Hi, CH,

    If you put the alignment left or leave it empty it should add the text with the correct z point.
    I hope it helps!

    Best Regards,

  • Sorry my friend, but I cannot understand what you are trying to do.
    I suppose that on columns you have coordinates, but still I don’t know what you want to achieve…

  • Hello.

    Can you help me?
