Now that sounds quite complex, but what it means is that this is optimized for CNC purposes. Now, it’s important to highlight here that Scan2CAD has done some calculations to represent the image as accurately as possible, whilst using as few vector nodes as possible. You can see that Scan2CAD has perfectly followed the original image, and we have vector profiles that represent the image. I can highlight the vectors by clicking the Highlight Vectors icon up here, just so you can see the accuracy. Again, we can compare that to the original raster image. So we’re now viewing the converted image. So what you can do here is play around with the settings until you’re happy with them, and when you are happy, we’ll click Okay to save the results of the canvas. We can compare that to the raster image just by switching. You see, we have the default here in vector lines and arcs. Bezier curves would be suitable for this image, and choose the type of vectors that you want to create. You can see we have a sharp and smooth slider here, just choosing the kind of definition that you want of the original image. And when we’re converting images for CNC purposes, we chose the Outline option in Scan2CAD. To do that, we’ll go to the convert raster image dialogue, which is this button. So we now have an image which is looking much more suitable for conversion, and we can go ahead and convert. So by using the smooth, we can smooth out the lines. As this is a JPEG image and that’s heavily compressed image format, it creates kind of image distortion. I also may choose to smooth the image by clicking this button that just smooths the lines out. Let’s just go with the default, it’s fine. So this is a multi-color image and we need to reduce the colors, so we’ll use the threshold tool. So we’ll jump first into the clean image window. First, to clean the image to make it suitable for conversion, and then to convert.
So the process in Scan2CAD is really two steps. But it could be a PNG, a BMP, just any raster image format supported in Scan2CAD, and we need to convert this automatically to vector and save out as DXF or G-code, or whatever your CNC machine supports. So we have as an example, this Ford logo, and this is a JPEG image. The CNC format may be DXF or G-code, and what we want is a nice, clean, cuttable vector profile of our images, which would be suitable for your CNC machine. So, with this video, I’ll be showing you how we can use Scan2CAD to convert your images to a CNC format.
