How to 'extract' one shape within another?

[Gemini80]

Hi All! I'm fairly new to Affinity Photo so pls bear with me 😉

 

I've got two objects/shapes - one a circle (blue) and one a crescent (black).

The black crescent is the top layer while the blue circle is below and is actually the full 'size' of the circle.

I would like to extract the blue circle's shape as can be seen in the below picture.

Is there a way to cut this exact blue shape out (down the to pixel) and then have it as a new stand alone object?

Thanks for all help and tips!!

Hi,

you can use Layer>Geometry>Subtract to get the blue shape. It will consume the source layers, so duplicate them before if required.

Thanks so much for your help! This worked perfectly! I have another question maybe you can help with 🙏

Is there a way to create a shape/object based on the inside of another shape? 

For example can I extract or generate a shape based on the dimensions of the empty inside portion of the zero in the attached picture?

Thanks for your help and patience!

Hi @Gemini80, select the 0, "Convert to Curves". Then "Geometry", "Separate Curves". Deselect and click in the centre of the resulting shape to select the part you wanted to get.

Gemini80: An alternative method to creating your first shape would be to use the Crescent Tool as can be seen in my attached video.

Gemini80: An alternative method to getting the ‘inner O’ can be seen in my attached video (where I move the ‘inner O’ rather than just deleting the ‘outer O’). Just another way of doing the same thing, but slightly differently.
