Building a half slab floor

[PhilHibbs]

I was watching a DocM video the other day, and he was making a stone slab platform over a mob spawner. He said that turtles would place the slab in the top half and not the bottom, so he was placing slabs manually. I found a shortcut for that, which is to use Wand of Equal Trade on a platform of solid blocks. Then, I tried using a Filler and that works as well, it places the slabs in the bottom half of the block. Any other ideas? I wonder if a turtle would work placing them upwards.

turtles place the half slab closest to them, unless there's a block 1 away. so if your turtle is in the air, placing a half slab above it, the half slab will be the lower half of the block, if it places it down, it will be the upper half of the block. this is reverse if there is a block 1 away though, as it will place the slab along that block

A Thermal Expansion Crescent Hammer can flip half slabs from bottom to top. If you make the turtle place then hammer the slab, then it should work just fine.

Builder's Wand? If you have Extra Utilities installed, it could be of great use, it allows for the extension of a structure formation by 1 block, only allowing a maximum placement of 9. And it does take the blocks placed from your inventory.
It's sad that I had to write that page just so I could post this...

another thing worth mentioning is if you use turtle.place() with a Thermal Expansion Crescent Hammer selected in its inventory, it will also flip the slab. So say you have the hammer in slot 16. This would flip the slab below the turtle.

turtle.select(16)
turtle.placeDown()
