The Split@Multiple command lets you split multiple entities using other entities as cutters.
Use the command with Lines, Circles, Arcs, PolyLines, Ellipses, Splines, InfiniteLines, and Rays, but not with RichLines.
To split multiple entities:
The entities are split at the intersection with the splitting entities.
Note: Parts of the original entities are not automatically deleted. If necessary, you can manually delete them.
