Building Information Modeling

Learn how CSI products work with other BIM software to provide efficient, integrated, open design workflows.

Increased Efficiency

With CSI software, collaboration between different AEC teams is efficiently handled through compatibility with other BIM software.

Workflow Flexibility

Start your model in a CSI software product and send it to another BIM product or vice versa.

AutoCAD® and BricsCAD®

CSiXCAD, a CSI developed plug-in for AutoCAD® and BricsCAD®, streamlines drawing production by directly interacting with ETABS® and SAP2000®. CSiXCAD provides a live link between structural models defined and maintained in ETABS or SAP2000 and the drawings documenting them in the CAD software. CSiXCAD generates a full 3-D model and automatically generates an initial set of drawings that can then be refined within the CAD software.


CSiXRevit, a CSI developed plug-in for Revit®, provides a bi-directional link between SAP2000, ETABS, and/or SAFE and Revit®.

Four options are available to interchange data:

  • from Revit to create a new CSI model
  • from Revit to update an existing CSI model
  • from CSI software to create a new Revit project
  • from CSI software to update an existing Revit project

These options provide for true round-tripping of data between CSI software and Revit.

Tekla® Structures

The link between Tekla® Structures and SAP2000® or ETABS® allows models to be started in either product, then transferred to the other. Round-tripping of models is possible, including accepting of changes when transferring from SAP2000 or ETABS to Tekla Structures. It is also possible to merge changes to a Tekla Structures model to an existing SAP2000 or ETABS model.


Support of IFC (Industry Foundation Classes) data models provides compatibility with other BIM enabled applications. SAP2000®, CSiBridge®, and ETABS® all support import and export of IFC 2x3 and IFC 4 formats.
