For all those times when you have wedges in your buildings and you need to make a rectangle floor connect to a rounded floor. Let’s make a building piece that fills the gap. It would be like pouring concrete in that odd space between foundations. Right now, I am using wedges and jamming them in where I can, which makes a fairly walkable, but extremely ugly floor. Then I toss rugs on it to hide the ugly.
I would think these pieces should also provide little stability to the structure, so for best building integrity, we would naturally have to plan for all the standard pieces.
If not this, then we need more wedge choices.
