Cut holes - problems with lists

Hi,

as a grasshopper beginner, i have a Problem with lists (at least i think this is my Problem...)

what i want is to cut out these cylinders from the other shapes. (see attachment)

but the only thing happening is, that it only cuts one! Whats wrong there?

Thanks a lot!!

Hello J,

you can try trim solid component to see if it is quicker, because solid difference, union etc components are a bit slow.

cheers

Thanks, it is faster... but only roughly a second ;)

any other thing i could do?

Thanks!

If you share your definition, I can show you how to do the boolean operations step by step or one by one with an anemone loop!

The main loop would loop over the number of Vornoi cells to subtract from and feed each one separately into a second, nested loop. The nested loop would iterate over all the cutting geometries and subtract them from the geometry that was input from the main loop.

I've attached a simpler example with only one loop that you can check out. Remember to install anemone first.
