Engineers retain full control over what data gets imported or exported. The plugin offers detailed mapping dialog boxes. These allow users to manually match Revit family types to CSI section names, preventing data loss or generation errors during the transfer. System Requirements
: Introduced support for slanted walls of rectangular shape and the ability to export rebar for walls, floors, beams, and columns from CSiDetail into Revit 2021.
Ensure that nodes and analytical lines are perfectly connected within Revit before exporting. Disconnected lines will result in unstable structures in ETABS or SAP2000.

Automatically maps Revit families (columns, beams, walls, and slabs) to CSI structural sections.
Downloading typically requires an existing license or a trial request from Computers and Structures, Inc. (CSI). As of early 2025, Autodesk has officially ended support for Revit 2021, which can complicate the installation of legacy plugins like CSiXRevit. 📥 Where to Download CSiXRevit 2021 System Requirements : Introduced support for slanted walls
For production work, though, CSiXRevit remains the only reliable two-way sync. Budget for it or explore Rhino.Inside.Revit + Karamba3D as a conceptual alternative.
CSIxRevit 2021 is a powerful plugin that connects Autodesk Revit 2021 with Computers and Structures, Inc. (CSI) software like ETABS, SAP2000, and SAFE. This tool enables seamless Building Information Modeling (BIM) data exchange, helping structural engineers transfer models between drafting and analysis platforms without rebuilding them from scratch.
: A separate external application is also available on the Autodesk App Store which offers a free version for basic analytical model transfers.
