1. ## Fibonacci Curve

Xara does allow you to insert a spiral, but, I couldn't see if the Fibonacci Curve is an option.

So, feel free to show me how to draw the Fibonacci Curve in Xara.

If you can, then some instructions on how you did it, would be good.  Reply With Quote 2. ## Re: Fibonacci Curve  Reply With Quote 3. ## Re: Fibonacci Curve

I know what it looks like, Gary.
And I know what the proportions are.

I'm asking how to draw this in Xara?  Reply With Quote 4. ## Re: Fibonacci Curve

Each section is a 1/4 circle.  Reply With Quote 5. ## Re: Fibonacci Curve Originally Posted by gwpriester Each section is a 1/4 circle.
Yup!
I know that too.

In fact, that's what I started doing. But, then it means trying to join all the 1/4 circles.

So, that's why I asked how you/someone would draw this in Xara.

Is there a way of drawing just one line which then follows the curve of the Fibonacci Curve?  Reply With Quote 6. ## Re: Fibonacci Curve

This is what I did.

But...
Is this the only way to draw it?  Reply With Quote 7. ## Re: Fibonacci Curve

Rik,
Draw a line with the Shape tool clicking on respective square points and then go back and pull out the handles to cleanup the arcs. You can check/align each arc by drawing a circle separately. Delete the circles and you're left with a continuous line. HTH  Reply With Quote 8. ## Re: Fibonacci Curve Originally Posted by Fred C Rik,

Is it not easier, as gwp has said and what I did, is to draw a circle and cut the 1/4 out of it.
That way, in my opinion, the arc is accurate.

In fact, to get the correct size of circle, all you need is to draw a square 100px x 100px, Then draw a circle of twice the size. i.e. 200px
Then align the quarter of the circle over the square.

However...
The continuous line that you mention, Fred, is a collection of points, which is the same as the arcs joined together.
Isn't it?
