Note: This topic is for Roombook users only. 
 A basic requirement to perform Roombook calculations is an AutoCAD-drawing with existing spaces and 3D building parts. 
-  Without spaces (rooms), no room quantities can be calculated. 
-  Spaces must be bounded by walls or space bounding lines; floors, ceilings, roofs, and furniture objects are optional and are only calculated when present. 
 Exporting in Excel templates requires Microsoft® Excel to be installed on the system. Otherwise the export cannot be performed.
