# Revit Structure
The link between Revit Structure and GSA is provided by the Revit plug-in, GsRevit, that is installed with GSA. After successful GsRevit registration, several GSA / Revit Structure link options are offered on the Revit Structure ‘Tools | External Tools’ menu. (The options are named from the Revit perspective.)
The following options are provided:
- Export to Oasys GSA – create a new GSA model from a Revit model or synchronise an existing GSA model with changes from a Revit model.
- Update from Oasys GSA – synchronise an existing Revit model with changes from a GSA model.
- Import from Oasys GSA – create a new Revit model from a GSA model.
Following the Recommended Practice will improve coordination between the GSA and Revit models.
