[Add bumps around uneven shape.]

I am currently trying to create a 'heart shaped tart'.

I have made a circular version (1), but am unsure on how to create the same effect with the heart (2) let alone any other shape than a circle.

The circular version (1) used a circle on top of a gear shape.

Any help welcome, thanks!

[Turn off multiple click to access layers]

In one of my projects, I have a tree like layer structure, with groups inside groups inside groups. When looking at the main middle part of the screen, if you click on an object which is inside a group which again is inside a group, you must continually double click to access the individual component you are clicking. Is there are way to turn this off? It is incredibly time wasting and annoying.

Any help appreciated, thanks,

Dan.

[How to stop stroke, where subtracted]

Hello!

I'm quite new to Affinity Designer and when I was trying to create something, and stumbled across this which I didn't understand. I've recreated it simply to show you.

When I tried to subtract two objects (1), by selecting them both (2) and clicking the subtract button, it ended up like (3). I now understand why it does this, but was wondering if there is a way to make it look more like (4).

I made (4) badly to show you what it might look like, but don't know how I would do it properlly, I guess is what I mean. Any help would be appreciated!

Thanks,

Dan
