OpenStreetMap 開放街圖
I've been mapping the Royal Holloway - University of London campus and I've had a couple of problems.
The main building is '8' shaped - a rectangular building with two large courtyards/quads. I'm not sure how to make it show like this, I've managed to cut out one of the quads but not the other. Anyone able to suggest how best to do this?

Take a look at the Multipolygon relation wiki page for details on this, and a step-by-step guide how to make them.
