Vector Graphics

Vector graphics are highly utilized in the field of graphic design and also form the foundational step of many of many digital fabrication workflows such as; laser cutting, CNC routing, vinyl cutting, and even (to some extent) 3D printing.

Being able to make good vector graphics allows you to put hand-drawn (or ideated) ideas into the computer in a format that can be read and used by these technologies, thus it is an extremely useful skill for any maker to have in their toolkit!

Vector vs Raster/ Bitmap

Vector graphics aren't like a photo.

Raster/Bitmap Vector
A raster image (for example a photo taken on a digital camera) is made up of thousands of little squares of colour called little pixels. If you take a raster image and stretch it to be larger than its original size it will 'pixelate' and lose quality. Whereas in vectors we can make our image as big or small as we like and it will never lose the crisp lines, this is because vectors are not made of pixels, instead they are made up of lines described by mathematical equations (thankfully we don't need to know the maths, the computer works that out for us!).

Because vectors are made of maths it is possible for various digital fabrication technologies to interpret this image and work out how to reproduce it in real life.

File Types

Vectors come in a broad category of digital file types, but the standard ones used in digital fabrication include; SVG, DXF and some forms of PDF. These are the file formats you export from the software you're using to make your vectors. Usually the software used by digital fabrication technologies will be able to read at least one of these file types, and it's good practice to export your file as all three kinds when you're preparing a file that you wish to bring into the fabrication lab just in case one file export doesn't work quite right.

Software options

Some of the most common Vector softwares used for digital fabrication are listed below.

Here you will find various info on getting started with various pieces of vector software. Remember that you have access to Linda.com which has a wide array of learning as part of your SLQ membership.

You also can come in during our Open Lab and Hack the Evening times to get hands on help, and these softwares are also covered in relevant inductions and workshops.
