OpenBuildings Designer

AECOsim Building Designer is a single building information modeling (BIM) software application that includes tools for architectural, structural, mechanical, and electrical systems design, construction documentation, and visualization of any type and scale of building.

The AECOsim family of applications provides unique building design, analysis, and simulation software focused on helping Architectural, Engineering, Construction, and Operations (AECO) practice leaders deliver high performance buildings. These applications enable architects and engineers to author and use rich information models. Below are some key advantages.

Model Anything

Model anything with total freedom, regardless of geography or size of project team to create virtually any form of any size or complexity, leveraging the power of GenerativeComponents, limited only by your imagination.

Immersive interaction

Immersive interaction to create and interact with 3D models, 2D designs, as well as innovative hypermodelling to integrate and access all available project information.

Trusted Deliverables

Trusted deliverables production to generate precise drawings and documentation, information-rich 3D PDFs, and 3D plots throughout the project lifecycle of design, construction and operations.


Comprehensive breadth and depth to integrate engineering geometry and data, including point clouds, from an unmatched range of CAD and BIM software and engineering formats like IFC and DWG.


Integrated, and project-ready AECOsim Building Designer empowers building design and construction teams to collaborate efficiently, by eliminating miscommunications and manual error-prone workflows.


Interdisciplinary modeling environment to integrate design and documentation workflows, eliminate barriers between disciplines, and shorten learning curves.

Performance Simulation

Performance simulation to evaluate and explore designs through lifelike rendering and animation, generative design, and built-in clash detection.

Extended capabilities

Extend the capabilities for users of commonly available design tools from Bentley, Autodesk AutoCAD and Revit, Graphisoft Archicad, and others in an integrated workflow through open standards

Predictive Design

Predictively design and optimize the performance of building systems and utilize information modeling within, and between, multiple disciplines using decision-support capabilities.


Power and Flexibility

Unlock design using the power and flexibility of OpenBuildings Designer from the start of your project to the end. OpenBuildings Designer offers complete design flexibility to:
• Create automated schedules from existing CAD drawings.
• Turn models from other conceptual design tools into drawings.
• Model objects with unlimited flexibility with no design boundaries.
• Build effective sites and terrains.
• Produce immediate and effective renderings, sketch images, drawings and schedules.
