Since I recently taught a 2 hour workshop on Sketch 3, I wrote a couple of emails to the attendees the week leading up to the class in preparation for what they’d be learning. In the workshop I was showing them how to use Sketch 3 as a tool, and how to take advantage of what it has to offer, while also highlighting what areas Sketch isn’t good at.

They are free, open to the public, and are meant to offer accessible education that isn’t your traditional schooling route. The monthly free meetups make for great networking events, educational opportunities, and an all around fun time. I can’t recommend them enough.

So what I mean by vector-based is that it is based on points: tiny dots that have an X and Y coordinate. If you think back to grade school, you probably had graph paper and were told to put dots at certain (X,Y) coordinates. After all the dots were on the paper, you would connect the dots with a line in a certain order, and you’d end up with a drawing!

Sketch 3, and any design program that can handle vectors, takes that same graph paper concept, and steps it up a notch. Here's a lovely SVG just for you.

Vector graphics uses geometrical objects, like points, lines,...
