2D barcode font for AutoCAD

[caddude1]

I am looking for a resource with a 2D barcode scanner font, which I can use with AutoCAD. My requirement is for repeatably sized and spaced images of a series of numbers for an optical scanner. I can create (in Adobe) the PDF file; however, the sizing and spacing of imported images (GIF files) become a challenge. The spacing is a critical point, as the product is positioning an AGV in a plant environment.

Thank you for the link @pendean. I am not looking for a barcode for a DWG file. I am looking for a barcode font to use within a drawing, which will create a 2D code for a numerical value. I have a series of codes that need to be read by a scanner to determine the position of an AGV and fed back for internal processing.

This one works for what I've used:

LibreBarcode39-Regular.ttf

Edit: Keep in mind you'll need a * as a prefix and suffix, as in:

*12345*

I think what we are looking for a data matrix code, not a 2d bar code.

Correct, Andrew. I misspoke on the original e-mail.

After creating the PDF from Adobe, just use AutoCAD's PDFAttach command to place the PDF into your drawing at a scale of 1.

@paullimapa I have done so, with success in generating the drawing. My challenge is that AutoCAD puts a complete border around the image. The scanner software fails when it sees the border around the open areas of a matrix. See the attached screen grab.

in AutoCAD enter PDFFRAME and set that to 0

@paullimapa That was the first option I tried. I am using AutoCAD Electrical, so that may have something to do with it also. I have tried setting the value to 2 as well with the same result in the plotted drawing. The value that I set the variable to does not affect the drawing. I have found this in multiple files I created to test it out. The attached image is a newly created file, with the value set to "0" as the command line shows.

My recommendation would be just to get the geometry into AutoCAD natively. 

We have a proprietary way of generating QR codes that output as SVG. That said, there are lots of online places that can generate QR codes and output them as svg. 

edit: you can use quickchart.io

URL > https://quickchart.io/qr?text=yourtexthere&format=svg

From there, I put it in a third-party application to convert it to dxf. (I use Inkscape, but anything that can convert svg to dxf should work)

Then once its in DXF, I just copy it into the drawing. 

It should be noted that our SVG only outputs line segments. So when it first comes in its polylines with no width, so i have to do one extra step of applying a line width to the imported dxf lines. 

before adding width

That’s odd. Could you share your pdf?

[caddude1]

Here is the PDF, SIr. thank you for your time and effort in helping me.

Regarding the border,  how about adding a polyline to cover the border?  Set its width to a small value (e.g., 0.1) and its RGB color to  255,255,255.

This prints as:

I'm using plain AutoCAD 2021 and the PDFFRAME setting is behaving as documented.

The only time the printed pdf shows a frame around the barcode is when PDFFRAME is set to 1
