This document describes how to exchange Building Information Modeling (BIM) data between Revit Structure 3 and ETABS, a three-dimensional physical object based analysis and design package developed specifically for building type structures, including commercial, residential, healthcare and educational facilities. This transfer of information is two-way: data can be sent from Revit Structure to ETABS, and then Revit Structure can be updated with changes made in ETABS. A link also exists for sending a new model created in ETABS to Revit Structure without any prior Revit Structure file.
Creating a single physical model in Revit Structure that can be accessed and used directly by ETABS reduces the time and effort associated with analytical model creation, as well as minimizes the chances of misinterpretation or data input error. Structural changes made in the ETABS program are easily coordinated with Revit Structure to keep the project, and hence drawings, up to date. The flow of information is idealized in the schematic below.
