The Spiral Tool's Partial Turns field will switch to use percentage if you have enabled 'Use Cusped Segments'.

Thanks, Sean. It would have taken quite awhile to figure that out :) 

What about clicking on the + icon, and how the effects differ between Mac and Windows? This is minor, except that it may puzzle users.

Ahh I see what you mean - this isn't actually limited to just that option, or in fact the Spiral Tool. It happens for any of the Quick Shape context toolbar labels. I suspect its tracking the value on Mouse down rather than mouse up. I'll pass it on to development and see what can be done :)

Thanks!

Hi lepr,
This is because it is a different formation of geometry when you're using Cusped Segments - it is no longer an angle, instead it is a distance along those cusped segments.

No, not in the AD beta on macOS in front of me. The partial turn percentages are relative to a full turn with 100% being equivalent to 360 degrees, 25% equivalent to 90 degrees, and so on. A cusped versus smooth version of a given Spiral has no difference except the underlying nodes are cusped versus smooth and the segments are linear versus curved. Or am I missing something?

It is most likely the values you're using make it look no different, however some instances (particularly using a large arc angle) will make this more obvious.
See my example below:

Sean, your example contradicts your explanation for the use of percentage instead of angle, which was "it is a distance along those cusped segments". I'm struggling to see how you came up with that explanation.

That example has 0 full turns and a 'partial turn percentage' (note the word turn that is in the tooltip) of 83% producing about 2.2 segments, not 83% of a single segment.

He came up with that example, because that's what I gave him in way of an explanation.

When using the cusped version, the spiral is formed from straight lines. The partial turn in this case is a percentage of the distance along these straight lines for a single 'turn'. To express this as an angle about a notional centre is less meaningful when the geometry is not an arc.  Using an angle would result in non-linear interpolation of the straight line segments.

Note, a 'turn' is a complete lap around, not a segment or arc.  Since arc angles (or more accurately, the circle divisor angle) can be arbitrary, a turn is determined as being independent of the arc angle for simplicity.  So - you can specify a spiral of 2 turns (a notional rotation of 720 degrees) but then set the arc angle to whatever value gives you the visual result you want.

I like the new spiral tool a lot, very handy addition to the existing tools!
Since I mainly work on the IPad version of AD, I want to report that for some types of spirals some of the panels to enter the values and the „bake appearance“ buttons are cropped. At least with the German version. I think nothing of the usability got lost, yet still I am wondering if a function remains hidden under looking glass, windshield wiper and magnet. And I am super curious to learn the full description of „Wic“ with the polygonal spiral. Using landscape format, with portrait format the tool is almost useless. 

—- after writing this I found out that the bar is scrollable! „Wic“ is „Wichtung“! I have never heard this word before. Richtung? Wicklung? Gewichtung? 
The scrollbar is very hard to grab without creating another spiral instead, especially when not using a pen but a finger. It also always jumps back to the left start after changing a value which make it very complicated to compare the results. Especially with the decreasing spiral some interesting features are hard to use.

Nevertheless a cool instrument!

Based on a feature request for a "concentric circles" tool, I've experimented a bit with the Spiral tool which is capable of creating concetric circles in the linear and decaying mode with Arc Angle = 360°, albeit all aligned to one side.

To center the circles subsequently:

  1. convert to curves
  2. Layer → Geometry → Divide
  3. Layer → Alignment → Align Center

Optionally, if you need rectangles rather than circles, select all nodes of the converted circles and convert them to sharp nodes.

Hi @Ash thanks for all this awesome new tools in 2.3.

The new Spiral tool is very interesting: I'm using Designer very rarely and have absolutely no clue how to use it.

Please recommend a how to video, many thanks.

I also checked the "Designer 2 Help" from the Help menu, found no starting point for noobs like me.

Appreciate any help! 😇
