How can I create a tight spiral shape? (Archimedean spiral)


I'm trying to create something similar to this example:

example sprial

What tool should I use, or is it just squares and circles attached together? Great if you know a tutorial for this effect.

Which part are you referring to? If it's the spiral, don't use the spiral tool. You'll want a linear/Archimedean spiral for that. You can find a tutorial on creating those here:

If it's the circled segments of the spiral, just split your spiral into individual paths and give them circular caps (under the 'Stroke' menu).

If it's neither of these, please clarify and I will try to help/analyse. :)

That kind of tight, uniform spiral is called an Archimedean spiral (aka Archimedes spiral). They can't be made by the regular spiral tool which only makes expanding (logarithmic) spirals.

enter image description here

There are two ways to make them I know of:

  • A method using art brushes described on vector guru:

    1. Take as many parrallel lines as you want loops
    2. Nudge one end of the lines up by the gap between the lines
    3. Group them and turn them into an art brush
    4. Apply the art brush to a circle of the appropriate size
    5. If you want to fix the spiral and edit individual segments, Object > expand
