We hosted a GSA User Group on the 30th and 31st January 2018 at the Institution of Structural Engineers in London. Presentations now available

Event Overview

A huge thank you to all of the attendees at our recent GSA User Group. We hope you all had an enjoyable time and learned from our developers, presenters, the Oasys team and also from each other. The two-day event proved to be a great opportunity for us to engage with users freely and gauge their preferences for future developments. We were also honoured to be joined by some leading figures from the structural, education, and API development industries.
