Pro Align Tools is an operator that enables interactive object alignment directly within the 3D viewport. Built for Object Mode, the tool provides real-time previews of object placement while users navigate and adjust selections. Its auto-alignment system quickly evaluates combinations of projection planes, origin points, directions, and depth to align multiple objects automatically.

Users can refine alignments using a set of 3D gizmos or sidebar controls, adjusting the projection plane depth and base points. The add-on supports aligning objects across global, local, view, and custom coordinate systems. Projection planes and reference points can be picked directly from mesh geometry by snapping to specific faces, vertices, or edges, offering control for spatial organization in scenes.
