What is Autodesk Forma?
Autodesk Forma is a cloud-based, AI-powered platform designed for architects, urban planners, and real estate developers to make data-driven decisions during early-stage site planning and conceptual design. Formerly known as Spacemaker (acquired by Autodesk in 2020 for $240M and rebranded in May 2023), it runs entirely in a browser with no installation required. The tool specializes in the critical pre-design and schematic design phases where site feasibility, building orientation, massing options, and environmental performance are evaluated.
Key features include seven types of real-time environmental analyses (sun hours, wind comfort, noise, microclimate, embodied carbon, operational energy, and solar energy), 3D massing and modeling tools with automatic floor area metrics, generative site design with AI-driven layout options, and real-world contextual GIS data ordering for any location globally. Forma Board serves as a built-in collaboration layer where teams can collect design proposals, annotations, and share proposals with clients without requiring Forma licenses. The platform supports import/export of IFC, OBJ, DXF formats and integrates bidirectionally with Revit, Rhino, Dynamo, and Autodesk Construction Cloud.
Forma is ideal for architects and urban planners working on feasibility studies, site selection, and early-stage massing; real estate developers evaluating site potential; sustainability consultants needing quick environmental performance data; and architecture students learning generative design (free through education program). It is not designed for detailed design documentation, interior design, construction documentation, or photorealistic rendering - those tasks are better handled by Revit, SketchUp, or rendering tools like Lumion and Enscape.

Frequently asked questions about Autodesk Forma
What is Forma Site Design?
Forma Site Design is an AI-powered, design and analysis software for data-driven planning in the pre-design and schematic design phases. It is used by architects and urban designers to plan sites with confidence. The tool has import/export support for IFC and OBJ formats, plus connections to Revit, Dynamo, and Rhino. It is available as part of the AEC Collection or as a standalone subscription.
What types of projects is Forma Site Design suitable for?
Forma can be used on all project types, especially complex projects in urban contexts such as mixed-use developments, multi-family housing, commercial buildings, and hotels. It excels at feasibility studies, site selection, masterplanning, and urban design where environmental performance and site potential evaluation are critical.
What are Forma Site Design's main features?
Forma has 3D modeling tools for massing and conceptual design, integrated environmental analysis with seven analysis types, automatic contextual GIS data ordering, and Forma Board for collaboration. Users can customize Forma by creating their own extensions or accessing a growing library of third-party extensions from envelope analysis to AI renderings and infrastructure design through the Autodesk App Store.
Which environmental analyses does Forma Site Design offer?
Forma's analyses include area metrics, sun hours, wind (AI/rapid and standard modes), noise (AI/rapid and standard modes), daylight, solar energy, microclimate, shadows, view analysis, and embodied carbon. Users also have the option to use analysis extensions from third-party providers or create their own analyses using Forma's API. Sun hours analysis was the most popular analysis in 2025.
How do I access Forma Site Design?
If you have the AEC Collection, you can access Forma at no extra cost. Standalone subscriptions can be purchased on the Forma Product Center. If you have an Autodesk account, log into your Forma hub. You can also start a 30-day free trial at autodesk.com/products/forma/free-trial. Students and educators get free access through Autodesk's education program.
What is the difference between Forma and Spacemaker?
Forma is the successor to Spacemaker. Autodesk acquired Spacemaker in November 2020 for $240 million and retired the Spacemaker brand on May 8, 2023, launching Forma instead. Forma merges Spacemaker's AI analysis engine with FormIt's conceptual modeling tools, adds embodied carbon analysis, expanded data availability, and includes Forma Board collaboration space. All core AI analysis capabilities carried over from Spacemaker.
Does Forma integrate with Revit?
Yes. Revit is now a Forma Connected Client, enabling bidirectional data sharing between Forma and Revit. Early-stage massing created in Forma can be transferred to Revit for detailed design development, where it becomes a geolocated native Revit model. Users can access Forma analysis tools from within the Revit interface without leaving Revit, and shared data access is enabled through the Forma cloud layer.
What is Forma Building Design?
Forma Building Design is a new cloud-based tool announced at Autodesk University 2025 for the schematic design phase, targeting Level of Development (LoD) 200-300. While Forma Site Design handles early-stage site planning (massing, feasibility, environmental analysis), Building Design extends to detailed building modeling with automated design functions, facade design tools, interior layout exploration, and integrated carbon and daylight analysis. It entered closed beta in late 2025 with expected general availability in 2026.
Is there a free trial for Forma?
Yes. Autodesk offers a 30-day free trial with full functionality and no credit card required. Forma is cloud-based so nothing needs to be downloaded. Students and educators get permanent free access through Autodesk's education program, with renewable 1-year subscriptions for eligible users.
What are the main alternatives to Autodesk Forma?
Main alternatives include TestFit (stronger for real estate feasibility with unit mix and parking optimization), Snaptrude (browser-based conceptual BIM with accessible free tier), Arcol (web-native collaborative BIM still in early stages), Hypar (parametric design automation for firms with coding capability), and Giraffe (planning compliance and visualization). Forma wins on environmental analysis depth with seven integrated analysis types, while TestFit is stronger for financial proformas and Snaptrude offers a more accessible entry point.
