AECOsim Building Designer

AECOsim Building Designer is a single building information modeling (BIM) software application for multi-discipline teams.  It enables architects, structural, mechanical, and electrical engineers to design, analyze, construct, document, and visualize buildings of any size, form, and complexity.  Its innovative capabilities help users lower project costs, save time, reduce project risk, and enhance overall project quality – while providing building owners with higher returns on their investments.


Integrate Disciplines with common workflows and coherent set of tools and libraries
Simulate Buildings easily with true Interoperability and built-in clash detection
Model Anything of any form, size, and complexity
Collaborate Efficiently by working across distributed project teams




Model walls, windows, perform space planning, and more
Produce plans, sections, elevations and schedules
Deliver quantity and cost reports and specifications
Create truly curved and double-curved surfaces, solids, and architectural assemblies
Leverage Bentley’s GenerativeComponents
Export data to Bentley’s AECOsim Energy Simulator and other energy analysis programs




Model steel, concrete, timber structures including walls, foundations, beams and columns
Produce plans, framing layouts, sections and elevations, and volume and weight analyses
Integrate with detailing applications including ProStructures, and others via ISM, CIS/2, and SDNF
Through ISM, leverage RAM, STAAD, and ProStructures for structural analysis and design




Model fully parametric air-handling, piping, and plumbing systems
Size ductwork correctly based on air flow, velocity, and friction rate using duct sizing tools
Place connectors for pipe, component hookups, and sloping of complete systems
Check wall attributes to determine fire damper requirements and produce plans and other reports
Export to Autodesk® Fabrication CAMduct® for fabrication
Access component product manufacturer libraries such as Lindab, NIBCO®, and TROX
Utilize XML files and VBA scripting to create custom catalogs and components




Design lighting and other electrical subsystems
Model raceways including cable trays and baskets, conduits, and wireways
Manage circuit devices, cable routes in raceways, and distribution board circuits
Accomplish point-to-point orthogonal and raceway routed length calculations
Achieve bidirectional interfaces with EDSA, ProDesign, elcoPower, and other industry-standard programs
Exchange data bidirectionally with Lumen Designer, DIALux, and RELUX
Produce plans, sections and elevations, schematic and block diagrams, drawing legends, and BOM’s


True Interoperability


Read, store, and place RFA content while maintaining all geometry, data, and behaviors
Employ point clouds of virtually any scale natively within the modeling environment as context for designs

Support common formats including i-models, DGN, RealDWG™, IFC, DXF, SketchUp SKP, PDF, U3D, 3DS, Rhino 3DM, IGES, Parasolid, ACIS SAT, CGM, STEP AP203/ AP214, STL, OBJ, VRMLWorld, Google Earth KML, COLLADA, Esri SHP, and more

Integrate geospatial information and ensure proper display within the proper context


Building Performance


Model, simulate, and explore a broad range of “what-if” scenarios using computational design tools
Perform height, slope, solar exposure, and shading analysis
Produce lifelike visualizations of models supporting point-and-shoot, photorealistic materials, lighting libraries, distributed network rendering, and key frame and time-based animation tools


Trusted Deliverables


Create 2D documentation dynamically directly from, and embedded within, the 3D model
Produce precision 2D and 3D plotting
Deliver documentation in less time due to robust design and production standards management
Apply site, project, enterprise, and international standards throughout design and documentation
Review and share markups of models and documentation


Model Anything


Create virtually any building of any form, size, and geometric complexity
Define rules to capture design intent, dimensional constraints, assembly relationships, and more
Leverage Bentley’s GenerativeComponents
