Angle Tool is an Edit Mode add-on designed to generate corner geometry from complex cross-section selections. By specifying an active edge or active vertex, users can rotate and extend selected mesh components around a pivot point to construct clean geometric corners.

The tool supports multiple operation types, including Extend Mode and Angle Mode, as well as a Curve Mode that allows users to define segment counts for rounded corners. It integrates a 3D viewport heads-up display for visual feedback, accepts numeric keyboard input for precise angle adjustments, and includes a toolbar gizmo for interactive manipulation.
