Build Mode Tips for Console (Asymmetrical Eaves & Free Rotation)
I did some experimenting on PS4 and figured out how to adjust only one side of a roof's eaves as well as free rotation.
To adjust only one side of a roof's eaves, grab the Eaves Adjustment Arrow on the side you want to adjust and hold the Square button.
You have to press X while still holding Square in order to lock in the adjustment, otherwise it will move both sides.
For free rotation of an item, hold L1 and R1 together and use the Right Stick to turn the object.
This is a difficult bit of information to find and I know I'm not the only person who's been wondering about it. Thought I would share what I found.
For XBox, I suspect it's the same corresponding buttons on their controller (seems to be with everything else.)
Edit: I just figured out how to raise the elevation of Build/Buy items as well. It requires the bb.moveobjects cheat being active. You then grab the item, hold L2+R2 just like you would to resize, but press up or down on the +pad (up raises elevation, down lowers elevation, left resizes smaller, right resizes bigger. Resizing doesn't require the cheat to be active, but elevation change does.)
