PolyTools is a retopology add-on that introduces a sub-mode workflow for generating clean topology over high-resolution meshes. The tool relies on a score-based quad detection algorithm to provide live previews and structural suggestions based on cursor position and nearby vertices. Users can define custom guide points, drag to generate continuous quad strips with adaptive edge spacing, or draw complete edge loops around cylindrical surfaces. Included are dedicated modes for brush-deleting specific geometry types, adjusting vertex placement, and merge-welding nearby vertices to close gaps. All actions integrate with Blender's native undo stack and viewport retopology overlays.
