For my calculations I only need a quarter of the whole geometry that I built because of symmetry reasons.
I tried to find out how to cut a geometry but didn't really get it. There were some examples with workplanes.
I tried with Blocks that I differentiate from my geometry so that only a quarter is left. But how can I then apply the symmetry node to the cutting plane? I tried by adding workplanes there but now I get a error in Form Union.
The file is attached.

Hi Anina,

add a cube in the position of the quarter you want to keep,
and then uuse the boolean operation "intersection" between both.

Thanks for the answer. But there are different geometries in each other. Is there a way to do the intersection between several geometry units and my new defined block? Otherwise I only get the quarter of the outermost block and all things inside stay the same.
