A BIMX file is a BIMx file created by GRAPHISOFT ArchiCAD, an architectural CAD program. It contains a virtual architectural project that includes 3D models and 2D drawing sheets. BIMX files are created in ArchiCAD when a user exports the project to the BIMx format.

BIMX file open in GRAPHISOFT BIMx Desktop Viewer BIMX files are often used by builders, clients, and consultants to view proposed models. The files allow you to view models interactively. You can walk through a building model and view construction details. If you come across the BIMX file on your computer you can view it using several BIMx programs. The BIMx Desktop Viewer for Windows and macOS (OS X) comes with ArchiCAD. However, you cannot save BIMX files with this program, only view them. BIMX files can also be viewed with the BIMx apps for Android and iOS. To upgrade to the PRO version of the BIMx Android app you must purchase the "BIMx PRO" function pack available as an in-app billing option inside the app.
