"...using 2D Curves and the SVG Export add-on (Bundled with Blender, you just need to enable it)

Assuming you already know the basics of how the UI works in Blender, everything in the pic below is all you need for an SVG editing template.

This is also a hint to the upcoming menu! There's an unlisted video posted on YouTube." — The Manager
