ReplaceSelection
名前の通りだと思うが、選んだオブジェクトをごっそり別のオブジェクトに入れ替える。

/* This wizard will replace a selection with an object or prefab.
 * Scene objects will be cloned (destroying their prefab links).
 * Original coding by 'yesfish', nabbed from Unity Forums
 * 'keep parent' added by Dave A (also removed 'rotation' option, using localRotation

これをAssets > Editorに置く。

するとメニューのGameObjectの中に追加される。

まず、この状態だとする。

４つあるCubeはサイズや位置が様々だ。
これらを選択する。

この状態から上で示したGameobject > ReplaceSelectionをクリックする。
出てきた窓でSphereを選択して[Replace]をクリックする。

こうなる。
