How to cut out this circle

[Pedro Suárez]

Hi guys, 

I dont' have to much experience on AD. I'd love to get a design similar to this one (see screenshot attached).

I don't know how to design the element under the small circle so that it can looks like it is "absorbing" the circle.

Can you please give me some advice?

Thanks

If you mean the red circle with letter k:

1. create the lower red shape with pen tool
2. add a circle (elliptical shape) on top
3. copy circle
4. select one circle and lower shape
5. Use geometry>subtract to cut out the shape
6. Select other circle.
7. select move tool
8. Hold shift and ctrl key while resizing circle with mouse
9. Or use transform panel, select center anchor point, activate aspect ratio lock, and enter new size in width or  height

Revised to create both circles at same origin

My first attached video shows a slightly different method to the one already given as the previous method makes it difficult to add the smaller circle in the exactly the right place. This method only works in Designer as only it has the Expand Stroke functionality.

My second attached video shows a slightly different way of doing it which allows you to easily manipulate the circles later. The result will be rasterised upon export, because of the Erase Blend Mode, but that might not matter since you will probably have an image in your design anyway. This method should work in any of the Affinity applications.

Hi @Pedro Suárez,

Another way to do it, draw the circle on the red shape. Group the two together. Select the circle, "Expand Stroke". Select the outline of the circle, put the blend on "Erase".
To move the circle, select it and the outline (without grouping them), move.
