INKSCAPE 3D TEXT FOR FREE
For free software, Inkscape is very powerful and there is a large community of users posting tutorials and YouTube videos. It is very similar to Adobe Illustrator or CorelDraw but is typically missing some of the most recent tools. Inkscape is an open source (meaning it is free) vector graphic software. A vector graphic can be easily used to generate g-code. Vector graphics are best for scalable images like logos or for engineering CAD. The position of lines and edges is calculated mathematically so the image will be very accurate and independent of resolution. They can also be defined with dimensions such that real-world objects can be represented in true scale. Because of this, they can be scaled to any size without losing quality. Vector graphics (SVG, DXF, DWG) use mathematical operations to calculate points or edges (paths) of shapes. They are not precise enough for representing a scaled image or a real-world object. Raster images are the most common digital image and are best for photographs and images with a lot of shading. Also, if the edge of a line were to fall between two pixels, it will get averaged and appear blurry or shaded. The image will appear clearly at its intended resolution but will lose quality when scaled since pixels will be averaged. Pixel size is set by the resolution of the raster image based on the number of pixels per inch. The image is made from a fixed number of pixels, but the size of a pixel is not defined. Raster images, (JPEG, BITMAP, PNG, TIFF) are created by a grid of coloured squares, called pixels. Difference between Vector Graphics and Raster Images Not all image types are suitable for generating g-code for CNC machines. Therefore, if we want to make something on a CNC machine we first need a scaled, mathematical model of it. The programs that control a CNC machine are generated mathematically from a digital model of the object or design that is to be created. Movement of a CNC machine is controlled by programs (G-Code) which move the machine to specific positions or along specific paths. 2.9 Harder (Manual) Way to Trace an Image for CNC.2.8 Will This Work for Text and Fancy Fonts?.1.1 Difference between Vector Graphics and Raster Images.1 Why Vector Graphics Are Required For CNC.You can see, that as stated originally, rounded shapes are not as easy to manipulate (letters X and R).Note: You don’t have to move the duplicate shape down and to the right, you could move it up and to the left (as shown below).You should now have a basic extruded shape.Repeat for all of the nodes that need to be deleted.Adjust the mode handles so that they are on top of the node they came from.With the node deleted, the node handles will become visible. Select the first node to delete, then press the delete button.They are highlighted in purple (see also screenshot below showing just the top of the letter T) On the letter T of the image above, I’ve selected the corner nodes that will need to be deleted.Then press the Edit nodes by path button (or press F2).Press Ctrl++ or click on Path > Union to combine the two black objects together.(You should now have the 2 black objects selected) Then with the shift key held down, click on the original black text.Alt and click the top duplicate to select the black duplicate just beneath it.Change the colour of the top duplicate to allow you to see it better.Create a duplicate of the duplicate in the new position.Move the duplicate slightly below and to the right using the down and right keys.Once done, click out of the text editor and then click back on the text once to select it.You’ll see in the picture below that most of the letters below have straight lines. Please note, this techniques works best on straight lines, rather than curves, so choose your font accordingly. Click on the T button on the tool panel and then click on the page.Firstly, open up Inkscape and create a new document.I’ve created this How-to guide using Text as an example, but it applies just as easily to shapes and other Inkscape objects. However, you can simulate 3D objects quite quickly and easily using Inkscape. Unless you are good with Blender, Google Sketchup or AutoCAD, real 3D is probably not achievable.
