Some artists work with both types of tracing, e.g. However, you need to be working with high-quality images with few colors for it to work well. This process is much faster than manual tracing. The software will detect the lines and edges present in your logo, and redraw them as vector lines, curves, arcs and other vector entities. Automatic TracingĪutomatic tracing typically involves a conversion program-such as Scan2CAD-which can instantly convert your raster image to a vector. Tracing manually can, however, be a time-consuming process which is why many opt for the more time-efficient process of automatic tracing. A computer, meanwhile, can only work off of the lines it can detect. This is particularly useful if you’re using an image that is faded or of low quality. You can look at your logo, for example, and know exactly where each line is and how the image is supposed to look. Manual tracing can be advantageous, as you’re far more likely to understand the image than a computer. You could either use a mouse to trace over every line, or make use of a tablet and graphics pen to draw over it. You would have to create a vector layer on top of your raster and then trace over it with vector lines. Originally, manual tracing was the only way you could create a vector from a raster image. This can be done manually or automatically. This process typically involves tracing over a raster image with vector lines. Vectorization is the process of converting a raster to a vector. Why not try something more innovative? You could create laptop decals of your logo or even mill it onto acrylic sheets with an LED light to illuminate the card. These ideas are just the tip of the iceberg-check out 11 CNC project ideas for more. This control software will then run your CNC machine.ĭon’t just be tempted to go for simply milling your logo. You can then convert the vector to G-code which will be read and turned into motion by control software. The process starts with converting your logo to a vector file format, which will dictate how your image is rendered. You need your logo in a vector format to take your design to fabrication. It also controls the rate at which your tool moves, the speed it rotates at and the type of motion required. The most common programming language is G-code, which controls how your machine’s tool moves-controlling its position and depth on the X, Y and Z axes. Examples of CNC machines include:ĬNC machines work by executing a series of pre-programmed commands. This means that they remove material from your initial piece. CNC machines work by using subtractive manufacturing techniques. For CNCĬNC stands for Computer Numerical Control. Take a look at our article covering raster versus vector for more information. The most popular vector types are AutoCAD’s proprietary format DWG, and the exchange file format DXF. on a business card, on your website or on a billboard. This is useful if you need different sizes of your logo, e.g. This means that no matter how many times you change the scale of the vector, it won’t lose quality. Vectors are made up of paths and rely on mathematical coordinates. They’re popular in graphic design and engineering because they don’t suffer from loss of quality. Vectors by comparison, are mathematically ‘perfect’ formats. They’re also resolution dependent, so your logo would need to be at the right scale to appear correctly. They’re made up of pixels, so when you alter the image, it can become blurry and undefined. Unfortunately, rasters come with a range of disadvantages. You’ll no doubt recognize formats like JPG, BMP and GIF. Rasters are commonly used for photographs-most of the images you see on your computer are stored in a raster graphics format. Why Convert A Raster To A Vector? For General Purposes Plus, we’ll show you examples of vectorized logos and how you can get Scan2CAD free for 14 days-letting you convert as many logos (and files) as you want. This guide will show you how you can use Scan2CAD to vectorize your logo for CNC-and we’ve even included tips to help you optimize your logo before you take it to your CNC machine. All you need to do is convert your raster design to a vector, and off you go! And the best part? Taking your design to fabrication doesn’t have to be a complex process. By using tools like CNC mills, laser cutters and routers, you could produce anything from laptop decals to wooden signs. CNC brings about a realm of possibilities in the maker movement.
