Removes whole cells from a cell grid by testing each one against a Solid. Cells are kept or dropped intact, never cut; use Trim Beams to cut the finished lattice itself.
The cell grid to thin out.
The Solid each cell is tested against.
Which cells pass: Center inside tests the cell centre, Fully inside all eight corners, Touching any overlap (conservative: it can keep a cell that only comes close).
Inside keeps the cells that pass the fill test; Outside keeps the ones that fail it.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
