Affinity Designer - Help Using Expressions

[Kiarian]

I've just been going through a tutorial on Expressions, using the Transform tab to create mathematical patterns.
I understand the basics of it, for example x+200 moves the Power Duplicated object 200 on the x axis, y+100 moves object 200 on the y axis, w*.5 reduces width by 50%, but what if I want a curved pattern?

I'm trying to get a simple inward spiral using a simple ellipse. I want this to curve outward slightly, but gradually decrease in size inwards, in a spiral pattern.
Can I use Expressions for this? The attached pic uses Expressions and Power Duplicate to gradually decrease size, but the spiral I have manually created.

Hi @Kiarian,

 

You can do this with the help of Symbols. Bring up the panel from View>Studio>Symbols. Check below for an example.
