In all the time we have been going round and round you could have created the world's most exquisite Finonacci curve Rik. :rolleyes:
I lifted this SVG from: http://www.bytemuse.com/post/fibonacci-spiral/.

I saved the <svg> HTML as a SVG file and dropped into Xara.
This give the black blob, which I set to be no fill, solid 2pt line and scaled.
The one here is 13 separate curves all grouped: http://www.downloadclipart.net/downl...cci-spiral-svg.

I think the Fibonacci spiral on its own is not that great looking. The curve looks better when constructed without the grid of the golden section rectangle. Just my personal opinion of course.
The curve posted by Ernie is much more pleasing to the eye. Just my opinion of course.
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.
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
