If you’re working with digital illustrations, splines usually create smoother edges than arcs. Carefully follow the outline of the image with the various drafting tools available.If the option is available, turn down the opacity of the image so that any lines drawn over it will be easier to see.Import your raster image into the program and scale it accordingly.Open up your preferred CAD software and ready up the plane or view where you want to place and trace your raster image.It’s a simple and straight-forward process that needs little instruction from those familiar with CAD programs. The idea is – if you need to produce a vector outline of a raster image, import the image file onto a CAD program and “trace” over the image with your CAD tools. With the advent of CAD and vectorization, the process of manual drafting has gone surprisingly unchanged – just with digital tools instead of physical ones. Manually creating vector outlines Manually tracing using paper Sourceīack in the day, drafters, illustrators, and machinists would have to set up a drafting desk with tracing paper and drawing implements just to produce a traced outline of their reference image. We’ll go through the three methods and by the end, hopefully, this would help you decide what proverbial route to take. What’s best suited to each user will depend on their priorities and considerations. Now, all these three methods have their own pros and cons. And as for dedicated conversion software, some programs are specifically designed and are made commercially available to those seeking to do raster-to-vector conversions regularly. There are also free and not-so-free online services that offer to automatically convert raster outlines to vector formats. Manual is just like what it sounds: you manually trace over the raster image to create an outline. The three main branches of conversion methods that you need to consider are manual conversion, online services (such as ’s ability to convert raster to vector for free online), and dedicated conversion software. But if you’re stuck with a raster image with an outline you need to use, there are a couple of ways we can go about converting an image for CNC. When it comes to dealing with outlines for logo design, illustration, and CNC machining, vector images will always be the standard. In practice, that means that raster images get blurry as you zoom in and vector images do not. But for the beginners out there, the basic difference is that raster images are made of pixels and vector images are made or scalable, machine-readable “ paths”. But how do you go about doing so? And what do you do if your reference image is a raster image?Ĭhances are, if you’ve dipped your foot into the design or CNC fields before, you’re familiar with the differences between raster and vector. The geometry gets connected in the regular manner, so things like double-clicking to select the entire chain can help save time.Be it for business, for design or for machining, many designers and CAD users will at some point have to deal with creating workable outlines out of reference images. In the example below you can see that two separate shapes were produced, but only one was required, so regular methods were used to remove what wasn’t needed. In some cases you might want to clean up the geometry to simplify it before creating an operation. As an image gets more detailed you’ll get more and more geometry. Even with a basic image, things like feathered edges can result in more geometry than you need. For example, importing a perfectly solid black logo against a perfectly solid white background should result in geometry outlining the perimeter of the logo. It looks at colour contrast and creates the geometry based on where it sees a certain amount of change. The Raster2Vector plug-in supports JPG, BMP, and SVG files. In the end you can use it to create an operation to cut the geometry whatever way you want. You might also want to project the geometry onto a 3D solid in some cases. Functions like scale, translate, and rotate can be used on the geometry to position it before adding tool paths. Once the image is imported you can use the geometry the same way as you would if you had drawn it in GibbsCAM yourself. You simply use the import button, locate the file, and the rest is done for you. This could be anything from a basic logo to a detailed picture. The CAM Solutions Raster2Vector plug-in for GibbsCAM gives you the ability to import raster images and have them converted to the vector geometry you’re used to.
