Welcome to Osdag help!

Osdag is a cross-platform free and open-source software for the design and detailing of steel structures, following relevant Indian Standards. Osdag is primarily built upon Python and other Python-based FOSS tools, such as, PyQt, OpenCascade, PythonOCC, SQLite, etc. It is developed by the Osdag team at IIT Bombay.

The OSI file of a sample design can be loaded through the File -> Load input option of the appropriate module.

Note

The examples highlighted inside a box are from the Release 2018-06-21 and older versions of Osdag. Please use the examples with the appropriate version of Osdag.
