Vectors aren’t just infinitely scalable however, they’re also easy to edit-you can modify each individual element of one. Made up of paths, you can zoom into them as much as you like without affecting the quality at all. Vectors are special in that they’re mathematically perfect. Vector images-like DXFs and DWGs-by comparison, are more likely to be encountered in graphic design and CAD. Not only are rasters resolution dependent, they’re also difficult to edit. These squares are pixels, which become more prominent when you try to change the size of an image. If you’ve ever zoomed into a photograph, you’ll have noticed tiny squares that appear, ruining the overall quality. Raster images-like JPGs, PNGs and GIFs etc-are all formed using a grid of colored pixels. You couldn’t go a single day without encountering some form of a raster image. In fact, if you’re new to the world of CAD, you might not even know what rasters and vectors are-let alone the differences between the two. If you’ve followed us so far, you might be wondering why exactly we need to trace an image to begin with. Software like Scan2CAD has automatic image cleaning tools called ‘Raster Effects’ which will make the image suitable for conversion.Īutomatic tracing can be a speedy process-here we’ve converted a TIFF to a DXF in mere seconds using Scan2CAD. If you’re working with low-quality images, however, you’ll have to be prepared for cleaning your raster image before conversion. Tracing software is increasingly adept at picking up on the subtleties of images and drawings now-some even come with Smart OCR capabilities. However, the process can be very time-consuming-particularly if you’re working with complex images or you need to convert more than one image.Īutomatic tracing, by comparison, is a speedier process. Manual tracing might be a suitable solution if you have a simple design which you can draw over with a small number of vector elements. It all depends on what type of image you’re converting and how much time you’ve got on your hands, as we discussed in tracing: manual or automatic. Automatic tracing by comparison involves using a conversion software to convert your raster design. Alternatively-using a more hands-on approach-you can trace an image using a graphics pen and tablet, enabling an arguably smoother process. This can be done in certain software with a mouse. ![]() ![]() Manual tracing-as the name suggests-involves tracing over a raster image by hand. This process can be done manually or automatically. ![]() If you’re a regular in the world of CAD and CNC, you might have heard of this process by another name- vectorization. It’s done by drawing over a raster with vector entities such as vector lines, polygons and text strings. Tracing is the process of converting a raster image into a vector image. ![]() We’ll even show you how to automatically trace an image with Scan2CAD if you’re looking for a more specialized trace! The answer is yes-Vectorworks comes with its own automatic tracing tool, which we will show you how to use. As you can imagine, the software comes with many capabilities-but can you trace using Vectorworks? Used primarily in the architecture, landscape and entertainment industries, Vectorworks is looking to transform the world through 2D/3D CAD and BIM design. For those of you who have only ever delved into the worlds of AutoCAD and SolidWorks, you’ve truly been missing out on the cross-platform CAD and BIM package Vectorworks.
