Specifying nothing will result in a projection looking at bearing zero (north). ie export map -proj [elevation 042 deg] -layout local -o "elv.pdf" or export map -proj [elevation 042] -layout local -o "elv.pdf". Therion defaults to degrees I think. In XTherion it is like this. Therefore if using degrees, you have the option of drawing up to 360 unique projected elevations. Bruce
