Professional NURBS surface modeler used for complex massing, parametric design via the bundled Grasshopper visual-scripting environment, and computational architecture; one-time license with native DWG, DXF, and IFC export.
The parametric placement is anchored by Grasshopper plus RhinoCommon and Python scripting; C2 3/5 reflects the .NET SDK and scripting surface, and C5 5/5 reflects Revit, Grasshopper, V-Ray, Enscape, Lumion, and SketchUp interoperability. C1 5/5 reflects the one-time license model, and firm-size fit is solo to growing.
from $995 Agent access: API Firm fit: Solo, Small team, Growing firm
Cloud-based parametric CAD/CAM platform with integrated design automation (Python API, Design Automation cloud), generative design, electronics design (PCB), sheet-metal and manufacturing workflows, and cloud collaboration.
C1 5/5 reflects the free tier and trial, C2 4/5 reflects the Python scripting API plus Design Automation REST API, and C4 5/5 reflects STEP, IGES, DWG, PDF, STL, and glTF support. C5 4/5 reflects Autodesk Docs, Unreal Engine, and OpenUSD/USDZ integrations.
Free tier Agent access: API Firm fit: Solo, Small team, Growing firm
Open-source, node-based visual programming environment for computational design and BIM automation, embedded in Revit and Civil 3D (also standalone as Dynamo Sandbox); build parametric graphs with Python and Zero-Touch C# nodes to generate geometry, bulk-edit BIM parameters, and automate repetitive modeling tasks.
C1 5/5 reflects free Apache-2.0 distribution, C2 3/5 reflects Python, DesignScript, and Zero-Touch C# scripting without a CLI, and C5 4/5 reflects embedded use in Revit and Civil 3D plus integrations with FormIt and Advance Steel.
Free tier + from $0 Agent access: API Firm fit: Solo, Small team, Growing firm
Open-source Python framework for computational design, analysis, fabrication, and BIM workflows in AEC, with dedicated Rhino, Grasshopper, and Blender integrations plus headless scripting, RPC bridging, and extension packages such as compas_ifc and compas_fab.
C1 5/5 reflects the MIT-licensed open-source distribution, C2 4/5 reflects the headless Python API plus Rhino/Grasshopper/Blender integrations and RPC bridging, and C4 5/5 reflects source-level portability with IFC support through the documented compas_ifc package. C3 2/5 remains honest about the developer-heavy setup and Python-first learning curve.
Free tier + from $0 Agent access: CLI / API Firm fit: Small team, Growing firm
Cloud-based, code-first generative design and space-planning platform where architects and engineers build, share, and run custom parametric "Functions" via an open-source C# BIM SDK (Elements) and CLI, plus a space-planning product (Hypar Space) for rapid test-fit and layout generation, exporting to Revit, IFC, and glTF.
Open-source, actively-maintained (near-daily GitHub commits through July 2026) generative-design SDK/CLI with transparent per-seat pricing, native Revit/Rhino/Grasshopper/Dynamo integrations, and open IFC/glTF export, backed by real enterprise customers (DPR Construction, Obayashi, Unispace).
Free tier + from $50 Agent access: CLI / API Firm fit: Solo, Small team, Growing firm
Parametric 3D mechanical CAD platform with assembly modeling, sheet-metal and manufacturing design, CAM integration, simulation, and interoperability with Revit, Civil 3D, and neutral CAD formats (STEP, IGES).
C4 5/5 reflects STEP, IGES, DWG, STL, and PDF exchange, and C5 4/5 reflects Revit-via-IFC, Fusion 360, Civil 3D, AutoCAD, and CAM integrations. C2 3/5 reflects APS plus .NET/C++ APIs, and the documented agent surface does not list a first-party cloud Design Automation or Python workflow.
from $2,500 Agent access: API Firm fit: Small team, Growing firm
BIM standalone solution for landscape design combining 2D, 3D, documentation, and visualization capabilities -- includes 8,000+ plant species, terrain modeling, grading, and parametric design via integrated Grasshopper tools; evolved from Lands Design plugin architecture and now offered as a perpetual or subscription license with Rhino 8 integration.
The parametric placement leverages integrated Grasshopper for custom parametric landscape workflows; C2 3/5 reflects Grasshopper scripting surface, and C4 4/5 reflects parametric definition portability within the Rhino ecosystem.
from $130 Agent access: API Firm fit: Solo, Small team, Growing firm
Bentley's parametric and associative computational-design environment for architects and engineers, delivered as a standalone free download or companion feature inside OpenBuildings Designer, with graphical nodes, script-driven logic, MicroStation-hosted geometry, and a .NET/API surface for custom node types and service-mode automation.
C2 4/5 reflects the documented C# add-in API, GC service mode, and script-function surface, while C4 4/5 reflects DGN-native modeling plus DWG, DXF, OBJ, IGES, STL, 3DM, and SKP exchange. C1 4/5 reflects the standalone free-download path, but C3 2/5 stays constrained by the Windows desktop and OpenBuildings/MicroStation learning curve.
Free tier + from $0 Agent access: API Firm fit: Small team, Growing firm
Mixed-reality authoring and fabrication toolkit for architects and builders that streams Rhino and Grasshopper models into HoloLens, Quest, iPhone, and iPad workflows, with QR-based model placement, live parameter controls, and Twinbuild viewing for Revit, IFC, DXF, and OBJ models.
The parametric placement is real rather than incidental: Fologram turns Grasshopper definitions into live mixed-reality tools with synchronized sliders, QR-code placement, and state-driven interactions. C2 3/5 reflects the documented Grasshopper component surface instead of a general REST API, C4 3/5 reflects Rhino/Grasshopper plus Twinbuild support for Revit, IFC, DXF, and OBJ viewing, and C1 4/5 reflects the free app entry point with visible in-app purchase pricing.
