One of the best things about Blender is the community it has fostered around it, a community that, other than being proactive about helping any other Blender user in need, is dead set on extending Blender's usefulness and spreading its open-source mantra.

These tools are a boon for engineering and architecture work among other things, where precise measurements are paramount to the work being produced. Check out the video below introducing the addon:
