Top 13 Best Free and Open source Building Information Modeling Software (BIM) List | 2018
BIM is a process involving generation and management of digital model that helps us to design, build and maintain the building through its whole lifecycle.
Best Free and Open source Building Information Modeling Software (BIM) List:
BIMx — BIM project presentation on mobile devices. Download BIMx & BIMx PRO: the mobile app for exploring and presenting BIM on handheld devices.

BIMX.ARCHICAD
xBIM provides a rich API to the IFC data standard. It allows developers to read, write, and update an IFC file in a few lines of codes. xBIM is a .NET toolkit, so developers can build everything from simple command-line applications, to extensions for Windows applications and Web services. An example of this would be: an “Add-In” for commercial BIM tools such as Autodesk Revit.

OPENBIM
Digital Project allows you to build BIM & CAD models regardless of geometric complexity. With powerful surface, wireframe & solid modeling, Digital Project can support the most demanding projects.

DIGITALPROJECT3D
Dynamo extends building information modeling with the data and logic environment of a graphical algorithm editor.

DYNAMOBIM
BIM 360™ construction management software enables almost anytime, anywhere access to project data throughout the building construction lifecycle. BIM 360 empowers you to optimize and manage all aspects of construction performance as well as those in the field to better anticipate and act via mobile/cloud capabilities.

BIM 360
ACCA software | Architecture, Engineering and Construction industries. Try the first free BIM software integrated with real-time rendering to assess your design choices in real time, the first BIM that even allows you to create highly immersive 3D video for architectural visualizations, an advanced BIM Design solution for integrating architectural design, structural analysis and cost estimating, in a simple, innovative, professional and much more convenient solution.

ACCASOFTWARE
with Tekla BIMsight – the easiest to use construction collaboration software.

TEKLABIMSIGHT
B-processor is BIM software that has been and currently is still developed by the Arhus School of Architecture in cooperation with the Alexandra institute. While it follows the main concepts and definitions of BIM, some essential ideas are quite different. This is owed to the fact that B-processor was developed from scratch, not as an add-on or further development of existing CAD software.

B-PROCESSOR
Open source BIMserver – In the heart of your BIM! The BIMserver software is free and open source (GNU Affero GPL) so it can be used by commercial software tools as well. It’s ideal to support your dynamic collaboration process in the AEC sector.

BIMSERVER
BIMsurfer WebGL viewer | The first open source WebGL viewer for BIM and IFC.

BIMSURFER
BricsCAD: 2D & 3D CAD software with industry leading support. BricsCAD BIM thinks logically, just like you. BIM models exists on a building site, and can contain one or more buildings. Each building can have multiple stories. You always have full control over the properties you assign to these BIM elements.

BRICSYS
TAD (The Architect’s Desktop) is an early stage Building Information Modeller. It does not work like other IFC based BIM such as Revit, Archicad, etc. Instead it has a simple approach to designing where it uses spaces to model all architectural elements. It is best suited for those countries that do not really employ standardized building components.

TEAMTAD
Revit LT™ BIM (Building Information Modeling) software helps designers produce high-quality 3D architectural designs and documentation in a simplified, model-based environment.
