ちょっとボリュームありそうだと思いつつ、こちらに挑戦しました。
Cutting multiple bodies with single tool body - Autodesk Community
ボディ（ソリッド）の結合の切り取りを大量のボディで行いたいようです。
本来の機能の場合は、
赤のターゲットボディは1個で、緑のツールボディは複数個指定が可能なのですが、
望んでいるのはその逆だと判断しました。
APIフォーラムに投げていますが、こちらでも転載しておきます。
（ネタが無いので）

気持ち薄々なので、厳密な処理はしていないのですが（外部コンポーネントのチェック等）
ソコソコ機能するとは思っています。
