Change Details

Use the circle tool to make a small circle in any hull type. Use line of symmetry tool(s) from the origin of the circle. Use "Remove/Replace" tool with "replace with active slot" checked to replace cubes with tetras/wedges/etc. The orientation of the blocks will not be mirrored by the line(s) of symmetry.

# put some hull cubes down # put symmetry in the middle # replace a single hull with an orientation and see that it doesn't mirror the orientation on the other side of the plane
