Crop multiple paths with a shape

[Trevor13]

I haven't found a solution to this yet on affinity or other vector programs, hoping someone has. 

In my work I am consistently trying to crop a series of vector paths using a shape (like a circle. I can crop one at a time, copy/pasting the circle over again and again, but that is very time-consuming. I've attached a very basic file to try and illustrate this. In the group on the left, basically I want the 'hairs' outside of the thicker circle gone, leaving only the parts that were inside, so it ends up looking like the group on the right. I manually edited this one to show you. I need these to still be vector paths, not expanded or rasterized.

Any ideas? Thank you.

Place the paths under the circle as child layers.

Or group the paths and mask the group. Here are both cases:

Thank you for the masking and child layers suggestions, they works visually, but not for what I need unfortunately. My end result is running this through an Axidraw pen plotter machine controlled via inkscape. Masking or layering the lines as children only hides part of the line, doesn't modify the underlying vector. So when running my machine, the original lines still exist and are drawn.

Maybe there is no simple solution

Did you mean something different when you wrote the following?

I understand ‘cropping’ and ‘masking’ to refer to the same thing as far as vectors in the Affinity apps are concerned.

Ahh I thought they had different meanings sorry. I had meant a more permanent removal of whatever is outside the circle.

Cropping and clipping are essentially visual in that they’re non-destructive. For what you want to do you need some kind of Knife Tool, and we don’t have that yet in the Affinity apps.
