The Inkscape Master Class is a comprehensive series of 50+ videos where I go over every tool, feature and function in Inkscape and explain what it is, how it works, and why it’s useful. Think of it as an interactive user manual, in video format, that you can refer to any time you want. Imported that pdf to inkscape to have a base to work with. Since inkscape support for pdf has improved over the years with the above approach I can get editable tables in my inkscape. Surely it's not integrated into the actual program but it's the best solution I came up with. This Inkscape tutorial demonstrates how to make an image of a penguin. The tips and tricks in this tutorial can be useful for other drawings as well. This is a good tutorial for beginners. Inkscape version 0.48.2 was used for this video. Inkscape is not a bitmap editor, like GIMP, but rather it is a Scalable Vector Graphics (SVG) editor.

Inkscape is a popular vector graphics editor used across industries due to its immense accessibility. It can be used to create artwork, digital graphics and illustrations like logos. And that’s not all. Inkscape can also be used to convert raster images to vectors using a trace feature. These vectors can then be used online or in a physical format.

Scan2CAD’s latest guide will show you exactly how you can vectorize using Inkscape. We’ll also show you when you should use Inkscape, and when you should opt for a more specialized solution like Scan2CAD. Plus, we’ll show you how you can get Scan2CAD for free.

  • What is Tracing?

If you’re new to the world of graphic design or CAD, you might not be familiar with tracing—otherwise known as vectorization. This process involves tracing over a raster image in order to create an editable vector image. This is how people are able to create the flawless images you might have seen on websites or advertisements. It’s possible to trace a raster and convert it to a vector in one of two ways—manual tracing or automatic tracing.

Manual tracing used to be the only method you could use to create a vector from a raster image. Using specific software, you can trace over a raster image by using your mouse. If you have a tablet and graphics pen, you could draw over the image. Manual tracing is beneficial in offering precision. While a computer might struggle differentiating between lines on a drawing, you would have no such issues due to your knowledge of the drawing. Unfortunately, manual tracing can be a time-consuming process.

The evolution of technology brought about a new method of vectorization—automatic tracing. This process involves making use of conversion software, which converts your raster to a vector automatically. It does this by detecting the lines and shapes present in your image and creating a vector output. This method increases work efficiency—you could quite easily convert dozens of technical drawings or designs in the time it takes you to manually trace one image. There are, of course, setbacks to conversion software, as they require you to be working with high quality images.

If you have many deadlines or a heavy workload, you should definitely opt for automatic tracing. It’s easy enough to vectorize using Inkscape or Scan2CAD, for example—eradicating the need to outsource CAD conversion.

But what exactly do the terms raster and vector refer to?

Rasters and Vectors

Raster images are mostly used for photographs. Most of the images you see on your computer are stored in a raster format. Images in this format are made up of pixels—tiny blocks of color. You might have seen pixels in a raster image when you’ve tried to scale the image up or zoom into it. Raster images are resolution dependent, so they need to be at the right scale to appear correctly, otherwise they lose quality. These types of images can be compressed using lossy compression or lossless compression. Common raster formats include JPEG, BMP, PNG and TIFF.

Vector images are mostly used in graphic design and engineering. They are made up of paths instead of pixels, which means that they are much easier to edit. When you make changes to a raster image, you make changes to the entire image. In contrast, you can make changes to individual elements of a vector image. Vectors rely on pure math, which is why you can increase the size of a vector without any loss of quality. Vectors are therefore infinitely scalable. It’s also possible to attach data to each element of a vector design, making them ideal for use in architecture and engineering. Common vector formats include DXF, DWG, PDF and AI.

Why is tracing important?

Tracing—or vectorization—is a fundamental part of dozens of industries, from graphic design to architecture.

If you’re looking to vectorize using Inkscape, you’re probably based in the graphic design industry. If that’s the case, you might be looking to create vector logos or images to feature on a website or an advertisement. You’ll want to avoid raster images because, more often than not, you’ll be able to see heavy pixelation. If you want a raster logo in different sizes, you’ll have to create separate ones—you won’t be able to re-size it due to resolution dependency. If you vectorize your logo, however, you can use the same logo for everything—from a billboard poster to a tiny business card.

Of course, it’s not all about graphic design. The ever-important CAD industry makes heavy use of vector graphics. Originally, CAD designers would hand-draw their designs and specifications. This made for a lengthy design and production process—any changes that needed to be made would result in entire designs being redrawn. This was thrown out of the window with the introduction and evolution of CAD software.

CAD drafters now create and edit their drawings in CAD software, meaning everything can be edited and changed quickly and efficiently. Vector graphics are the industry-standard format for CAD software—you can edit each individual entity and reuse them when you create new drawings. If a CAD drafter has an old technical drawing in a paper format, they can scan them and then convert them to a vector format using tracing. This vector image can then be opened in CAD software where it can be turned into a 2D or 3D model.

Inkscape is a free and open-sourcevector graphics editor, similar to Adobe Illustrator and CorelDRAW. It can be used to create and edit vector graphics including illustrations, logos and line arts. Inkscape stands out in the market due to its use of SVG—an open XML-based W3C standard—as the native format. It’s used across a range of industries, from marketing and branding to engineering and design. It can take you through an entire design process with a professional-grade design format ready for publication on the internet or in a physical form.

Inkscape is cross-platform which means that it can be used on Windows, Mac OS X and Linux. One of its biggest advantages is that it is free to use and distribute—you can even look at the source code. You can easily vectorize using Inkscape with its Bitmap Trace tool, which we will discuss shortly. Using its automatic tracing tool you can quite easily turn your raster artwork into vectors. You might even use Inkscape in CAD and CNC applications. Of course, like other free software, Inkscape does come with some limitations, which we will discuss briefly later in this article.

Inkscape comes with a variety of drawing tools which you can make use of to manually trace your raster image. It can be a time-consuming process, however, which is why we’re concentrating on automatic tracing instead.

Inkscape comes with a simple trace feature—Trace Bitmap—which enables users to trace and convert raster images to vectors. The process also involves specific trace features which enable users to alter aspects of their raster and vector output—from the color to the background. By using these features, you can modify your vector until it’s completely to your liking.

You can start the process by loading your image into Inkscape. Head on over to File > Import and choose your raster image. Once you’ve selected your image, start the trace by clicking Path > Trace Bitmap. Inkscape then gives you two options for tracing—you can choose between single or multiple scans, each giving you different settings. Single scans should be selected if you want to create a single path from the image. Alternatively, multiple scans should be chosen if you want a group of paths.

Single scan

  • Brightness cutoff: uses the shade of a pixel to figure out whether it should be black or white. The higher the threshold setting, the darker the image will become.
  • Edge detection: creates a path based on the differences in brightness of pixels. The threshold settings then adjust the darkness of the output image. A higher threshold will produce a darker output.
  • Color quantization: produces a path based on the differences in color. The ‘number of colors’ setting allows you to specify how many colors you want in your output. An algorithm is then used to turn these theoretical colors black or white.

Multiple scan

  • Number of scans: the number of paths. If you’re using multiple colors, you’ll need to increase the number of scans.
  • Brightness steps: allows you to specify the total number of scans.
  • Colors: makes use of the number in the scans box to then determine how many colors it should output.
  • Grays: the same as the color setting, except that it creates a grayscale version.
  • Smooth: applies a Gaussian blur before the trace option. This eradicates any rough patches on your paths.
  • Stack scans: gets rid of holes in path coverage.
  • Remove background: gets rid of the background, giving you a vector on a transparent background.

Additional options include: suppress speckles, smooth corners and optimize paths.

After you’re happy, click Update to see a preview of the trace. If your lines are too thick or too thin, you will have selected an unsuitable trace mode. Inkscape recommends testing out the different settings for the tracing tool in order to determine which one suits you best. You can then click OK to create the paths. If you need to make any changes, you can click ‘Edit paths by node’ to adjust the nodes and curves.

Inkscape comes with a variety of advantages. It’s free to use which is a great bonus when you compare it to software like CorelDraw which costs $499. In addition, it’s open-source which means you can make your own improvements and changes to the software. If you’re looking to convert simple artwork to a vector graphics format, then Inkscape is perfect. However, if you’re looking to convert more complex images with a higher number of colors, then Inkscape is the wrong fit.

You might also find Inkscape to be unsuitable if you’re looking to convert technical drawings for use in CAD software. All technical drawings are different in some way. For example, electrical plans consist of precise straight lines while contour maps contain more curves and polylines. Unfortunately, Inkscape only provides a generalized trace. This means that you’ll get a generalized trace that takes the same variables into consideration no matter which type of technical drawing you’re converting. When it comes to these types of drawings, it is vital that you get a specialized trace that caters to each type of drawing you’re converting. This is where Scan2CAD comes in.

Scan2CAD is a conversion software that specializes primarily in the conversion of technical drawings to editable vector images. It supports a vast array of different design types, ranging from engineering drawings to site plans to contour maps. It can also be used in a variety of industries, from glass reproduction to metal sculpting to routed signs. You can quite easily scan a technical drawing and convert it to a vector, ready for use in CAD software. Of course, it’s not just limited to technical drawings—you can also convert raster images like logos or artwork.

So what makes Scan2CAD different from other conversion software or Inkscape? It’s simple, really. Scan2CAD was developed for the primary purpose of conversion. It gives users a specialized trace—when you use Scan2CAD to trace a technical drawing, you’re given a variety of vectorization settings. These settings come with pre-programmed variables that enact exactly how your conversion is carried out. If you’re converting a contour map, for example, Scan2CAD will convert the shapes into Bezier curves or splines. In short, Scan2CAD offers you a specialized solution that caters to all of your vectorization needs.

Plus, the process takes only seconds to complete!

Step 1: Locate the problems

Before you begin the vectorization process, you first have to make sure that your input image is of the best quality. After all, if you’re using a tiny raster image that’s already pixelated, you’re not going to get a great output. This is even more important when it comes to technical drawings. If you’ve scanned a drawing, the image has to be of a high quality. Otherwise, Scan2CAD (or any other conversion software) won’t be able to identify the lines and text in the image.

There are a variety of common problems that plague raster images, making it difficult to produce an optimal vector output. If your image contains heavy pixelation, or is blurred in some way, then you won’t get a great output. This also follows for dithered, merged or hairy lines—in which case the software won’t be able to differentiate between text and shapes. Additional image issues are highlighted below.

Don’t bother converting any raster image that contains any of these problems…

Step 2: Fix the problems

Scan2CAD comes with a wide variety of pre- and post-processing editing features which allow you to produce the most optimal result possible. We’ve highlighted a few of the main features, but for more information you can check our raster quality checklist or our top 10 raster effects.

  • Pick the right format. Formats like JPEG are compressed using lossy compression, so each time you edit them they lose quality. Scan2CAD recommends the use of the TIFF format which uses lossless compression. If you want a great output, you have to start with the right file format.
  • Reduce colors. Vectorization is an easier process for images that have a less amount of colors. This gives a clear contrast between the image and the background, allowing the software to pick up on the shapes and text easily.
  • Thresholding. To avoid issues like grayscale, you can use thresholding to divide your image into black and white pixels. This is especially vital in scanned images. Scan2CAD offers two different types of thresholding:
    • Simple thresholding, which applies the same settings to the whole image.
    • Adaptive thresholding, which applies different settings to different parts of the image.
  • Cleaning tools. Once you’ve got everything else sorted, you can make use of Scan2CAD’s wide range of cleaning tools.
    • Thicken lines to fix dithered or broken lines.
    • Remove holes or speckles to tidy up the image.
    • Smooth to remove hairy edges surrounding your image.

Step 3: Vectorization

Once you’re happy with your image, you can move on to the easiest part of the entire process—vectorization. Scan2CAD can convert your drawing in a matter of seconds, so you don’t have to worry about time-consuming conversions anymore. Once you’ve finished the process, you can save your vector as a DWG, DXF or even as G-code if you want to send it straight to your CNC machine. It really couldn’t be easier with Scan2CAD.

Scan2CAD isn’t just used for converting technical drawings for use in CAD software: it can also be used for CNC and CAM purposes.

CNC machines work by executing pre-programmed commands, the most common language of which is G-code. To start the CNC process, you need your raster image in a vector format. Once you’ve completed the vectorization process in Scan2CAD, you can then convert your vector to G-code which will be read and turned into motion by control software. This CNC control software will then run your machine.

Using Scan2CAD, you could create any type of CNC project, from laptop decals to laser cut jewelry to wooden plaques—the world is your oyster. If you’re interested, check out how to vectorize a logo for CNC to see it in action. Or, if you’re looking for an in-depth look at how CNC works, take a look at how to convert an image for CNC.

Not interested in converting technical drawings or creating your own vectors? Sometimes we just want to get stuck into a project rather than getting weighed down by the tiny details. Scan2CAD isn’t just a conversion software, it’s also a source for all things CAD, CNC and CAM-related. So if you want to get started with your own projects, why not make use of Scan2CAD’s cut-ready CNC designs that are free and ready to use? These packs include 6 or 7 designs in a DXF and JPG format.

Worried they’re not suitable? That’s okay—each week brings in a new theme, ensuring that you’ll be rewarded with exciting and innovative designs every single week.

If you’re converting raster images for a website, advertisement or just general graphic design purposes, then you can’t really go wrong with Inkscape. After all, it is free to use. However, if you’re looking for a software that offers you a specialized solution for all of your conversion needs, then look no further than market leader Scan2CAD.

Practice

Scan2CAD doesn’t just stop at converting images. It also comes with a raster and vector editing suite so you can optimize your image before and after conversion. With its batch processing feature, you can automate the conversion of hundreds of files at once. If you’re converting drawings that contain a lot of text, you’ll also be pleased to hear about Scan2CAD’s Smart OCR feature, which allows users to convert text and even train the software to recognize new fonts and handwritten text.

Inkscape® (free software)

The following guidelines give a detailed step by step overview of how to set up your drawings for us using Inkscape drawing software. You can download a free copy of Inskcape here.

How to setup a file in Inkscape®

Using our drawing templates

If using our materials, we recommend downloading our drawing templates. They help to verify scale and material type. Materials come in all different sizes depending on the maximum sheet size supplied from the manufacturer.

Templates for Inkscape can be downloaded from the corresponding material page in the materials gallery. Once downloaded, select and open the sheet size that is large enough for your components.

Working with the drawing templates

Inkscape Practice

Multiple files from same material
If you want all your parts cut / engraved from the same material, arrange into multiples of the same templates and draw as many as required .

Inkscape For Macheavenlyboard

Multiple files from different materials
If you want parts cut / engraved from multiple materials, Use the corresponding templates for chosen material

Template sizes
Try and use templates that suit best the scale of you drawings. i.e if your components can fit within a 1000mm x 500mm template, don’t position your drawing on a 2000mm x 1000mm template with lots of excess.

If you have lots of small components from the same material it’s best to draft these on a series of smaller templates approximately 1000mm x 500mm rather than on one large template. Cutting & engraving densely populated files over large areas can cause the material to warp during the process.

If you have elements of your drawing that will only fit onto a large template but don’t need to use a whole sheet, just leave the remaining areas blank.

If using your materials or not using a template

For

You’ll need to resize the page to the size of your material.

  • Set art board to match the size of the material in mm
  • Select File > Document Properties > Set width / size
  • Allow 5mm from the border of the material.

Configuring units & colour mode

  • Measurements: 1 unit = 1mm
  • Draw components at actual size
  • if copying and pasting vectors from another file, make sure that they are at the scale you require within the template
  • Make sure you are working in RGB mode
  • Select File > Document Properties > Colour Management

Laser cutting Lines

For everything you would like to have laser cut draw out your vector lines in:

  • Red: RGBA: 255,0,0,255
  • Stroke weight: to 0.010mm

Vector engraving / scoring strokes

We have established optimized vector / scoring settings for all our materials to achieve a consistant result with the best clarity. The depth is very shallow and cosmetic just scratching the surface. The Strokes & Fonts engraving sample (line weight 0.25pt) demonstrates the clarity on each material. These can be viewed in the materials gallery.

For everything you would like to be vector engraved (scored,) set the lines to:

  • Blue: RGBA: 0,0,255,255
  • Stroke weight: to 0.010mm

Raster engraving strokes & fills

While we can raster engrave thin vector lines, it’s advised that you vector engrave/ score them. All vectors you would like raster engraved must be indicated by a vector fill.

To turn a line into a filled shape in Inkscape:

  • Set strokes to a minimum of 0.40mm (anything thinner wont engrave)
  • Select your line and select Path > Stroke to path command
  • Set all fill colours to: Black: RGBA: 0,0,0,255)

Arrange parts economically

When arranging artwork for engraving that have a few components on one sheet, it’s best to keep all of the raster engraving as close together as possible and in horizontal row. See more on nesting components for raster engraving»

Raster engraving standard appearance & depth

We have established optimized settings for all materials. In raster engraving terms the marking is cosmetic, shallow and typically a balance between legibility and cleanliness. The Strokes & Fonts sample on the material pages demonstrates the clarity achievable on each material.

Bespoke depths / treatments:

If you would like to achieve a deeper result or an engraving a little heavier let us know your specification. In laser terms depth is usually specified in microns. Our standard engrave is approx 0.25 microns (depending on material) and has excellent legibility.

h4. Up to 2mm is considered deep for most materials:

It is achievable, but the laser has to run slowly meaning the concentrated heat build up makes the material appear quite burnt / heat scorched. It is also more expensive to process. Raster and vector engraving is not absolute science in terms of depth specification and therefore not suitable for making mechanical grooves or any features requiring precise depths. Achieving a certain depth is balance in variation between the laser power and speed. A depth of engraving will always be within a tolerance of +/-0.2mm.

Nesting components & minimum cut widths

Nesting:

  • If compiling a file with lots of components on one sheet of material, make sure there is a gap of at least 2mm between the components.

Small details / cut widths:

  • The laser burns away a portion of material which ranges from 0.1mm – 0.4mm depending on a lot of different factors. This means any areas in your design where cut lines come closer than 0.5mm together they could burn away entirely. Any details narrower than 1mm are likely to be very fragile and in some cases can cause the material to warp whilst cutting. You need to be aware of this when drafting your drawing:
  • As a benchmark, we recommend that minimum cut widths be no smaller than the thickness of the material. E.G. If cutting from 3mm acrylic, its best not to allow cut widths less than 3mm. We can go smaller but we can’t be held responsible if you your components become fragile for you application. You can browse the minimum cut width tests in the materials galley.

Maintaining continuous vector geometry

Try and make sure that all your vector paths are continuous. If a lines are constructed from more than one path, make sure that you join / close the nodes.

  • To do this, use the Use the Edit paths by node tool. The nodes will appear as grey diamonds
  • Select the nodes you want to join holding down the shift key as you select them. The diamonds will turn blue
  • Select the Join selected endpoints with a new segment button
  • The nodes will join together and the path will be in one continuous vector line

Reducing anchor points / simplifying drawing

Draw with the least amount of nodes possible without sacrificing the appearance. If you can reduce them, we suggest you do. The machines will read your drawings a little easier. Too many nodes can also have an affect on quality.

  • You can reduce the number of nodes with the Simplify tool.
  • Select the stroke path you wish to simplify with the Edit paths by node tool.
  • Select Path > *Simplify. Repeat if necessary until you have maintained a balance between preserving appearance and reducing the nodes

Using text - converting to paths

All text used needs to be converted to paths.

  • Select text, then select Path > Object to Path

This is to convert the text to vectors and preserve your font. If you don’t do this and we don’t have your font installed here, the file will open in default font Myriad or Arial. The middle islands of some letters will fall out when laser cut which can make the text difficult to read. If you would like to prevent this one option is to use a stencil font.

Embedding images within a drawing

There are 2 options when working with images in INKSCAPE, embedding and using tracing to bitmaps. In both cases images need to be at least 300 dpi. and in grayscale. We recommend you carry out any image editing in photoshop or Gimp or any other image editing software.

  • Import your image into your file: File > import
  • When prompted select Embed from the link or embed image notification
  • You can lay vectors over the top of the image for laser cutting of vector engraving

Tracing image bitmaps

You can also trace the image you want to incorporate within your file to convert it to vectors. To do this first select the inserted image

  • Select Path > Trace Bitmap
  • Experiment with the tracing options for the desired effect
  • Make sure your traced shapes are a solid Black RGB 0,0,0

Cleaning up drawing / removing overlapping lines

When drafting your drawing ensure that there are no duplicate vector strokes stacked up on one another. If you don’t get rid of them the laser will cut / score these lines repeatable, ruining the material and damaging the laser bed.

It’s also worth viewing your drawing in outline mode just to make sure you don’t have any white fills that are obscuring any hidden vector strokes. To do this:

Inkscape for macbook

Inkscape For Macbook

  • Select View > Display mode > Outline. This mimics how the laser cutter will “view” and process your drawing

Breaking nodes with in paths

If you have placed components directly beside each other you are likely to have parts of the vector shape with duplicate lines. In this case you will need to break apart the nodes manually so that they share the same line. In the examples the middle line between the rectangles will be broken and shared

  • Select all vector strokes and fills. Select Path > Object to Path to convert to nodes
  • Select one of the shapes using the Edit paths by nodes to show nodes (grey diamonds)
  • Select the node on one side of the line to be broken. (It will turn blue)
  • Select the node on the other side of the line to be broken from the path. (it will turn blue)
  • Select the Break path at selected nodes button
  • Select the middle of the line you have just broken from the shape and press delete
  • One of the rectangles is now sharing a stroke from another. If you move the rectangle aside you can see this more clearly

Saving your file

  • Select File > Save As
  • Format Inkscape SVG *.SVG)
