Fibonacci Curve

**Egg Bramhill** · 12 February 2019, 06:45 PM

Problem with trying to use Xara's smooth bezier curves is they're not very good. Try creating a circle from four lines, converted to smooth curves. Definetly not a circle.

Inkscape has a better tool using it's spiro beziers.

Maybe Xara could have developed such tools also?!

Yes, with the spxe for Xara You couldn't be precise. To make with this tool a perfect fibonacci curve Yuo may be able to put in the parameter of 1.68034 for the curvator and set the begining to 90°.

I made 6 years ago a videotut on vimeo how to in Illustrator https://vimeo.com/46122411. Illustrator has the segmentcurve tool, so it is easy doingt it.
In Xara I cut out a segment from a circle. Here a quick and dirty tutorial for Xara: https://www.franta-net.de/snagit/fibonacci-xara.mp4

Nice one, ernie.
I like it.

I'll have to give it a go in Illustrator and see how I get on.
I've never really used Illustrator much. But, it seems that there's a 'curve' tool. That seems to make the job a lot easier.

Thank You Rick.
I know it's not all so easy like it looks.

Wish all Xaraistas a great „Valentines Day!”

If you look, you'll find that it exists everywhere in nature!

Yaeh Rick,
You'r so right.

Everywhere we can see the golden ratio by fibonacci.
The great masters of art in the mediavel created their arts on this rule. We also as Xara-artists may think about this and bring it in our art.
