Asked in my challenge thread, but may be seen by more here, so...
For environments, use 1 unit = 1 foot (or 3 units = 1 meter for the metric among us ) to help you with scale. Make sure entryways are at least 6 units (6 feet/2 meters) tall and 4 units (4 feet/1.3 meters) wide. Feel free to make them larger.
What units are used? If it's the grid units, then what should the grid be set to? I tried setting my grid to represent feet, and the building grew to where I could no longer see it.
I apologize if this is a very silly question, but I can't find it in my books anywhere.
