SnapElements

Remarks

⚠ A set rather than a choice, because they compose and they compose in one direction. Holding vertex and surface at once is strictly better than either: a vertex snap only answers when there is a corner within reach, so falling through to the surface when there is not is what makes the pair a better drag rather than a mode switch. The order they are tried in is Vertex, EdgeCentre, Edge, Face — smallest first, which is the same innermost-wins rule SubObjectPicker uses and for the same reason.

Fields and properties (8)

• None

  Nothing. A drag goes where the pointer says.

• Increment

  Whole steps of the grid, measured from where the drag began.

• Grid

  The world lattice itself, so everything dragged ends up on the same one.

• Vertex

  A shared position of the geometry under the pointer.

• Edge

  Anywhere along an edge of it.

• EdgeCentre

  The midpoint of an edge, which is what a wall is centred on.

• Face

  Wherever the view ray meets the surface.

• Geometry

  The three that need geometry rather than arithmetic.
