voxel hands could have a box check on/off for snap to grid like blocks do.
ive just had the worst time of my life every time i try to make terrain clear out look decent without either A giant bubbles outside the basement walls visible from surface, or B: leftover floaty tiny chunks of voxel that break interior vehicles when rammed into.

TLDR : im bad at voxel hand and drills, pls allow the voxels to snap to building block sizes and grid alignment the same way blocks do but just clear out a Cube 1:1 or 1:1.01 scale box
