**What is OnBox?**

It is a free and open source Revit App that helps day to day tasks like renumbering elements, creating structural components, topo surface manipulations, and content management.

Originally created in 2014 as a collection of macros to improve and speed up workflows for multi-story buildings, it had its first public release in September 2016 as a Revit Application. It became very popular in Brazil and other countries like Spain, Mexico, and Portugal, helping AEC students and professionals across 39 different countries to be more productive and efficient.

The tool is available in English or Brazilian Portuguese depending on the language of Revit that you have launched.
