What it doesBrowser-based AEC design platform with one AI-native workspace for site analysis, programming, massing, BIM and presentation. The vendor calls it "the design OS for AEC". Upload an RFP or project brief (PDF) and a site, and AI generates a program and diagrams that you refine in the Snaptrude editor. Lists AI program creation from prompts or RFPs, a spreadsheet program live-linked to the 3D model, deep research on building regulations, zoning codes and site constraints, one-click adjacencies, area and solar analysis, one-click mass-to-BIM conversion (walls, floors, roofs), AI renders, real-time collaboration, and export to Revit (.rvt, via the Snaptrude Manager plugin) and Rhino. Also promotes an App Builder (describe a workflow, get an app). Vendor says it is SOC 2 Type 2 compliant. A testimonial on the homepage claims 4 days of work done in 4 hours (customer claim, not verified). Re-read Oct 17, 2026: homepage unchanged in substance (App Builder banner, SOC 2 Type 2, Revit and Rhino export); the pricing page's Free plan now lists 1 project instead of 3. Re-checked Oct 19, 2026: homepage unchanged in substance (design OS for AEC, App Builder banner, RFP upload, Rhino and Revit export, SOC 2 Type 2). Re-checked Oct 20, 2026: homepage unchanged in substance (App Builder banner, RFP or brief upload, Rhino and Revit export via the Snaptrude Manager plugin, SOC 2 Type 2); the security section also lists end-to-end encryption and private IP isolation for AI queries, and the footer links comparison pages for SketchUp, Revit and ArchiCAD. Re-checked Oct 22, 2026: homepage unchanged in substance (design OS for AEC, App Builder banner, RFP or brief upload, Rhino and Revit export, SOC 2 Type 2, end-to-end encryption and private IP isolation). The pricing page now meters AI use in credits (see pricing). Re-checked Oct 24, 2026: homepage unchanged in substance (design OS for AEC, App Builder banner, RFP or brief upload, Rhino and Revit export via the Snaptrude Manager plugin, SOC 2 Type 2, end-to-end encryption and private IP isolation for AI queries).Cloud software for site planning and analysis, described by Autodesk as AI-powered. Site context from the Forma Data Marketplace (terrain, buildings, roads), terrain editing with pad volume and mass balance insights, 3D massing, and an AI-powered Site Automation tool that generates and compares layout options, plus housing, parking, line-building and floor-plan/unit tools. Analyses include sun hours, daylight, wind and noise (each with a rapid machine-learning prediction mode and a detailed simulation mode), microclimate, solar energy, shadow, view and total carbon (US hubs). Forma Board handles design review tied to Revit sheets; AI rendering is included with render limits. Proposals go to Revit as a geolocated native model; IFC/OBJ import and Dynamo and Rhino connections are listed. Autodesk says Forma Site Design replaced Spacemaker, whose subscribers were migrated. A customer quote on the page cites a 60-hour design done in 4 hours (customer claim, not verified). Re-read Oct 17, 2026 (rendered in a browser): the old Forma overview URL now redirects to a Forma Site Design product page, which still calls it AI-powered cloud software for site planning and analysis and now lists sending a Site Design proposal into Forma Building Design, viewing Forma Data Management files and Revit sheets in Forma Board, and a Forma for Construction connection. Its FAQ describes Forma Site Design as an initial set of capabilities of Autodesk's AEC industry cloud for pre-design and schematic design. Re-checked Oct 19, 2026: (WebFetch; a plain request returned 403) the product page still calls it AI-powered cloud software for site planning and analysis and lists the same tools and analyses, with Site Automation and terrain editing marked Enhanced and Forma Board adding AI-powered rendering in context (render limits may vary). This read lists sending proposals to Forma Building Design and Revit and sharing projects in Autodesk Construction Cloud; it no longer names the Forma for Construction connection we noted Oct 17. Subscriptions include 8x5 support, SSO and usage reporting. Re-checked Oct 21, 2026: product page unchanged in substance (AI-powered site planning and analysis, Site Automation and terrain editing marked Enhanced, rapid machine-learning wind and noise predictions alongside detailed simulations, Forma Board with AI-powered rendering, Revit, Rhino, Dynamo, IFC and OBJ connections). Customer quotes on the page were not used. Re-checked Oct 23, 2026: integrations still list Forma for Construction alongside Forma Building Design, Revit, Forma Data Management, Dynamo, Rhino and App Store extensions; the FAQ now also explains how the product differs from the wider Autodesk Forma platform, and lists 24x7 online support options. Re-checked Oct 25, 2026 (read through a fetch service; a direct request returned 403): unchanged in substance (site context from the Forma Data Marketplace, terrain editing with pad volume and mass balance, 3D Sketch, AI-powered Site Automation, housing, line-building and parking tools, sun, daylight, wind, microclimate, carbon, noise, solar, shadow and view analyses, Forma Board with AI-powered rendering, and export to Revit as a geolocated model). Customer quotes and time-saving figures are vendor content and not used.

Where the vendor descriptions differ

  • Where you start: Snaptrude says you upload an RFP, describe the project and attach a site, and its AI generates a program and diagrams that you refine in the Snaptrude editor; it also lists research on building regulations, zoning codes and site constraints. Forma Site Design starts from site context: terrain, buildings and roads from the Forma Data Marketplace, geolocation by map, coordinates or address, and terrain editing with pad volume and mass balance insights.
  • Modeling: Snaptrude links a spreadsheet-style program to the 3D model so changes update both, models in 2D and 3D, and converts early massing into a BIM model with walls, floors and roofs in one click. Forma lists 3D Sketch, AI-powered Site Automation for generating and comparing layout options, housing, line-building and parking tools, and floor plans and units, with geometry imported from Revit, Rhino, IFC or OBJ.
  • Analysis: Forma lists sun hours, daylight potential, wind (rapid machine-learning predictions or detailed simulation), microclimate, total carbon (US hubs), noise, solar energy, shadow and view analyses. Snaptrude's homepage lists area and solar exposure analysis, and its Pro plan lists daylight and illuminance.
  • Hand-off: Snaptrude exports to Rhino and Revit and says .rvt exports keep materials and parameters, with firm-standard Revit objects usable in its BIM mode. Forma sends a proposal to Revit as a geolocated native Revit model, continues into Forma Building Design, brings Autodesk Docs sheets and models into Forma Board, and lists Dynamo and a Rhino extension.
  • Pricing: Snaptrude publishes plans: Free $0 (75 credits a week, 1 project, no exports or BIM mode), Pro $50 a month billed yearly ($600) or $60 monthly (500 credits a week, BIM mode, exports), Organization $100 per seat per month (2,500 credits per seat a month, teams), and Enterprise custom. Forma Site Design shows starting at $59 a month; its FAQ lists $85 monthly, $700 annually or $2,100 for 3 years, or the AEC Collection at $460 monthly, $3,675 annually or $11,030 for 3 years, with a free trial.
  • Not used here: customer quotes and time-saving figures on both pages, and Snaptrude's claim to be the only early-stage tool of its kind.
