Is the city one big component or are there a lot of smaller components?

[erzane]

some small ones, and inside one small component there are some smaller buildings which are components to

For numereous reasons, I think your only option is to copy the city and explode all components and sub-components. Intersect that with the cylinder, remove all unwanted geometry and make that into a component.

You can follow these steps:

• put the cylinder in the right position
• select all components which are touched by it (parallel top view)
• group them, explode all in that group (colored in the example, just to clarify)
• use booltools with the new group and the group with the cylinder
• delete remaining components and add hole
