Using Height lock with placeables

Getting placeables to do what you want can be very tricky. The arrow keys move placeables about, use Ctrl as well to rotate them. Page Up/Down adjusts the height of your placeable.

Height lock (‘Z’) locks the placeable in place. Use to fix its height in absolute terms. You can use this to get bridges to stick where you want them for instance. And useful for 'mixing' into terrain if they otherwise look too stuck on top of the terrain.
