If you tick those without needing them, then it might turn out some false positives in the final image, so don’t tick them if you don’t need to tick them. In this case, there aren’t any vertical and angular text, so I’m gonna leave those unticked. Now, if you have any vertical or horizontal text, you would also want to click on these two. I think it might be the room labels, so let’s zoom into any one of those, and then click and drag across its height to set the maximum character size automatically. For the character size, let’s set the maximum character size by clicking on select from image, looking for the largest text here. So click on that, set some of the settings right. Technical vectorizing OCR, when you click on vectorizing OCR, a new OCR tab is going to pop up here. You can try to exploit the other ones if that’s more appropriate for your own image. There are a couple of presets that you can also choose, but usually when you’re working with LibreCAD, it’s either Architectural or Electrical or Mechanical house. As for vectorization presets, let’s stick with the default architectural.

The OCR function just converts those text images into editable text. And since we do have some text objects in the original raster image, I’m going to click on vectorize and OCR. In this case, I think we might want to stick to the Technical Vectorization method. Okay, so say that we’re okay with the edit here and we’ve cleaned up the image as much as we can, we just have to click on convert raster image here on the upper left right next to the clean image button. If you want, you can also add text here if that’s something that you might want to do before vectorizing the image. You can even draw rectangles and circles and other polygons here. The main things you might want to consider are the erase duo for any speckles or holes or anything you might want to erase in the image that you don’t want to include in the vectorization.Īnd we also have some other drawing tools such as draw line, draw arc, and draw Bézier. There are a couple of other editing options here. Now, we can click on okay to execute the changes into the raster file. See, it does kind of make it… It’s a little bit more neat. Let’s see what happens if we click on this image. Thicken lines just makes thinner lines more visible, and it kind of tries to smooth out these jagged edges like this one. In this case, this is a pretty clean image so there’s no need for us to use that. Remove speckles and holes to remove any visible graphic noise or holes that we can find in the image.

Now, we have a couple of clean image options here. But if it is possible, always go for the option of clicking on threshold. You’ll see that if the image is already black and white, it’s going to be grayed out like this one, and it won’t be possible to click on it. In this case, the option isn’t available because the original image is already black and white. Now normally, you would want the click on threshold to turn the image black and white. So let’s clean up the image by clicking on clean image here in the upper left. In this case, you want to first clean this up, convert into a vector file and then save it as a DXF file.

Let’s open up a sample floor plan raster file here.

Today, I’m gonna be showing you how to use Scan2CAD to convert either raster or vector images into a DXF file format that you can open up on LibreCAD. With the raster files, you’ll have to trace over them to vectorize them, and when it comes to vector files, it can only really handle its native DXF vector file.

LibreCAD is a nice piece of software but it gets kind of tricky when you try to import different image files into it.
