Loop Copier is a modeling tool that duplicates mesh parts along selected edge loops without causing the deformations typically associated with Blender's native Array and Curve modifiers. It is designed for constructing hard-surface elements such as tank treads, chains, and bullet magazines. Users can adjust the number of copies, rotation, scale, and offset directly from the interface. It functions on both closed loops and open edge lines, and includes an option to align the copied meshes to the face normals of curved surfaces.
