Quick Replace provides tools to rapidly swap the mesh data of selected objects in the viewport. It introduces a dedicated N-Panel with two lists for organizing items into custom categories and object groups. Users can populate these lists from a dropdown menu or by loading currently selected objects directly.

Once configured, the add-on relies on scroll wheel hotkeys to cycle through and replace meshes. Users can loop through their object list starting from the top or from the active object by combining the scroll wheel with Shift or Control modifiers. Additional shortcuts allow for quick category switching and rotating selected objects in 90-degree increments along the Z axis.
