A tool for those who work with Blender, made for my own use, but others might find it useful too. It is a simple rectangle, 3000 Blender units high by 100 wide and deep. Markings on the sides show the 250, 500, 750 and 1000 unit positions. Just add as you would any furniture item and use to measure the height of your room, rotate to measure horizontal distances. Perfect for when you want to make a room of a certain size (I want to make a room about the size of my ballroom, how big is it I wonder?) or to guage the size that your furniture products will be when finished. Its also derivable in case you want to add measurements of your own....
