Finding bounding box

Nothing comes to my mind.
How to find a single bounding box for a set of detached curves?
30 min later: got it. I found a solution through finding min max valued of the endpoints and building volume out of it.
Curious about anyone having better idea.

Just uses Union Box? Right click on the bounding box component and select Union Box. But that is not the smallest possible one, if this is what you are after.

You can Group the curves and use a Bounding Box on the group.

Thanks guys, didn’t know the solutions is so simple.
