The drawing space allows you to draw over an architectural plan after importing underlays (. PNG's) into the workspace. Once imported, a quick sequence of calibrating and setting user preferences allows drawing thermal zones or spaces. The process is repeated for all zones and levels of the building.
Filter Aspects enables a Zone to be filtered to enable quicker administration of the model.
Filter Aspects by selecting the filter that defaults to 'Clockwise'. Select either 'Anticlockwise', 'Longest Aspect' or 'Shortest Aspect' to filter by rotation or length.
