Smart Loops Toolkit provides a suite of mesh editing operators for manipulating edge loops and adjusting bevels. The add-on includes tools to subdivide and unsubdivide edge loops, fix n-gons, and straighten both loops and faces. It also features unbevel and rebevel operators that allow users to modify or remove existing bevels without distorting surrounding geometry. All operators can be accessed from the N-Panel Edit tab or the right-click context menu while in Edit Mode.
