调研方向

Start in Editor/SceneView/Snapping/SceneHandles.Snapping.cs, where SnapSettings already defines the TODO-marked GeometryVertex, GeometryEdge and GeometrySurface modes. Study how pivot-to-grid and bounds-to-grid snapping are implemented there, and look at the UV tools for working examples of snapping to geometry edges and vertices. Done means moving brushes, generators and their handles snaps to vertices, edges and surfaces of other geometry; the README's feature list should be reconciled once that lands. This is a substantial geometry/editor feature with no failing test to start from.

描述

enhancement UX

Snap what you move (brushes, generators, their handles) to the vertices, edges and surfaces of other geometry, not only to the grid.

SnapSettings already has GeometryVertex, GeometryEdge and GeometrySurface (Editor/SceneView/Snapping/SceneHandles.Snapping.cs), but they are marked TODO: only pivot-to-grid and bounds-to-grid snapping are done for moving objects. The UV tools already snap to the geometry's edges and vertices.

The README lists "Precise snapping to surfaces, edges, vertices and grid lines" as a feature, so it should be updated once this is done (or until then).
