We rank the main tools architects evaluate in 2026 by how well they handle IFC, BCF, and IDS, how flexibly they license, and how cleanly they fit into multi-discipline model coordination.
One disclosure up front, because it matters for how you read this. Nordic BIM Group is the Archicad distributor in Finland, Norway, and Sweden. We also resell Solibri. We have a commercial interest in Archicad. So we have scored every tool against the same published openBIM criteria, cited our sources, and explained the reasoning. Read it, check the sources, and decide for yourself.
For architects who put openBIM first, Archicad and Vectorworks lead because both come from Nemetschek, both were early to buildingSMART IFC4 certification, and both treat IFC as a first-class format rather than an export afterthought. Revit is the most widely used tool in the segment and its IFC handling improved in the 2025 and 2026 releases, but architects still hit documented friction when exporting complex geometry to IFC. Allplan is a strong openBIM option that sits closer to engineering and detailing workflows. Bentley and Trimble tools exist on the edges of the architectural conversation and serve different primary jobs.
The honest summary: there is no single "best" tool. There is a best fit for how your office works and how much you value an open, vendor-neutral data trail.
openBIM is a way of working where the model and its data move between tools in open, vendor-neutral formats. Three standards from buildingSMART do the heavy lifting.
IFC (Industry Foundation Classes) is the open data model for buildings. It is an international standard, ISO 16739-1:2024, designed to be read and written by any compliant software. BCF (BIM Collaboration Format) is the standard for issue-based communication, so a coordinator can flag a clash, attach a snapshot, assign it, and track the resolution across different tools. IDS (Information Delivery Specification) is the newer standard that lets a project define, in a machine-checkable way, exactly what information a model must contain.
For architects, the practical payoff is independence. When your geometry and data live in IFC, you can change tools, bring in a consultant on a different platform, hand a model to a contractor, and keep your information intact. openBIM removes the lock-in that comes from a single proprietary file format.
Six criteria, all openBIM-led, all checkable:
We did not score on rendering, marketing polish, or feature count. Those matter, but they are not what openBIM is about.
| Tool (vendor) | IFC maturity and certification | BCF | IDS readiness | Licensing in 2026 | Primary fit |
| Archicad (Graphisoft) | High. buildingSMART IFC4 export certification. IFC treated as a core format. | Yes | Supported in recent releases | Subscription only | Architect-first design and coordination |
| Vectorworks (Nemetschek) | High. First to receive IFC4 Reference View 1.2 export certification (2019). | Yes | Supported | Subscription, with perpetual still sold in some markets | Architecture, landscape, and entertainment design |
| Revit (Autodesk) | Improving. IFC export reworked in 2025 and 2026, but complex geometry export still has documented friction. | Yes | Improving | Subscription only | Multi-discipline engineering and large-team coordination |
| Allplan (Nemetschek) | High. Strong IFC and openBIM support, IFC4 in the 2026 release. | Yes | Supported | Subscription | Architecture, engineering, and detailing |
| Bentley (OpenBuildings, MicroStation) | Capable, infrastructure-leaning. | Yes | Varies | Subscription | Infrastructure and large civil projects |
| SketchUp / Tekla (Trimble) | Partial (SketchUp) to strong structural (Tekla). | Tekla yes | Varies | Subscription | Early concept (SketchUp), structural detailing (Tekla) |
Archicad was built by architects for architects, and that shows in how it handles spatial thinking, plan generation, and team collaboration in design phases. On openBIM it is mature. Graphisoft holds buildingSMART IFC4 export certification, and Archicad supports IFC, BCF, and IDS as part of its standard workflow rather than as a bolt-on.
The current release, Archicad 29, added an AI Assistant in beta, an embedded helper trained on Graphisoft documentation and course material that answers workflow questions and can filter model elements through natural language. A full commercial release is expected during 2026.
Where it fits: offices that design buildings and want open data without fighting their tool to get it.
Revit is the most widely used BIM authoring tool in the architecture segment, especially in larger multi-discipline teams. Its IFC handling has improved. Since the 2025 release, category mapping moved into the main export setup, so you select IFC classes from a dropdown instead of typing them by hand, and the 2026 release continued that work with smarter coordination and faster workflows.
The friction is real and documented. When Revit exports complex geometry to IFC, file size and data fidelity can suffer. One worked example showed a swept profile growing from 10 KB to 270 KB, a 27-fold increase, once a filleted corner was added, which is exactly the kind of detail that appears in door and window frames, hardware, and furniture. On import, Revit tries to rebuild native elements from IFC, which works for simple walls and breaks down with complex shapes.
Revit and Archicad both produce excellent buildings. They are built around different workflows. Revit centers on an engineering and large-team coordination model. The choice is about fit, not about one tool being weak.
Vectorworks was the first software to receive IFC4 Reference View 1.2 export certification, back in 2019, and it has stayed committed to open workflows since. It exports IFC to coordinate with consultants on other platforms and links out to Rhino, SketchUp, Cinema 4D, and other design tools. It is strong for architecture, and it is the common choice for landscape and entertainment design.
Where it fits: design-led offices, including landscape and interior practices, that want openBIM and flexible licensing.
Allplan is a serious openBIM tool that leans toward engineering and detailing alongside architecture. It supports IFC and BCF, links cleanly with other tools including Revit and Archicad, and the 2026 release advanced its IFC4 support and added a new model viewer. For offices that work tightly with structural and fabrication colleagues, it is worth a look.
Bentley's OpenBuildings and MicroStation are capable and openBIM-aware, but their center of gravity is infrastructure and large civil work rather than building design. Architects rarely choose them as a primary authoring tool.
Trimble covers two different jobs. SketchUp is widely used for early concept and massing and plays a supporting role in openBIM through IFC, but it is not a full BIM authoring tool for documentation. Tekla Structures is a strong structural detailing and fabrication tool with solid IFC support, used by engineers more than architects.
The licensing picture shifted in a way that affects every architect's budget.
Archicad moved to subscription only. Graphisoft stopped selling new perpetual licenses to new customers after the end of 2024, existing customers could buy perpetual through the end of 2025, and active SSA and Forward contracts are serviced through the end of 2026. A conversion program for legacy customers moving to subscription ran with extended terms into 2026.
Revit has been subscription only for years, with no perpetual option.
Vectorworks is the outlier. It still sells perpetual licenses in some markets, which suits small firms and sole practitioners who prefer not to be tied to an annual cycle.
Published list prices give a rough sense of annual subscription cost, in the region of 2,400 to 3,500 USD per seat depending on tool and edition, but these are indicative international figures. Nordic pricing, education terms, and multi-seat agreements differ, so confirm a local quote before you budget.
openBIM is not only about your authoring tool. It is about what happens when your model meets the structural, MEP, and contractor models.
This is where BCF and a dedicated coordination tool earn their place. Solibri opens, navigates, and federates IFC models across architectural, structural, and MEP disciplines, runs model checking, and drives issue-based coordination through BCF. The pattern that works: each discipline authors in the tool that fits its work, everyone publishes to IFC, and coordination and clash detection happen on the federated model with issues tracked in BCF. No one is forced onto a single platform, and the audit trail stays intact.
This is the real argument for openBIM. It lets a project use the best tool for each job and still hold together.
A few honest scenarios.
If you are an architecture office that wants open data, fast plan generation, and a tool built around the way architects think, Archicad is the natural fit, and it is the tool we know best.
If you work in landscape or interior design, or you want the option of a perpetual license, look closely at Vectorworks.
If most of your collaborators are already on Revit and your work is deep multi-discipline engineering coordination, the tools and people already around Revit may outweigh its IFC export friction, and openBIM via IFC still lets you exchange with everyone else.
If you sit close to detailing and fabrication, Allplan deserves a place on your shortlist.
Whatever you author in, plan your coordination layer early. The tool that checks and federates the models matters as much as the tool that creates them.
What is the best BIM software for architects in 2026? For architects who prioritize open standards, Archicad and Vectorworks lead on openBIM maturity, both backed by buildingSMART IFC4 certification. Revit is the most widely adopted in larger teams. The best choice depends on your workflow, your collaborators, and how much you value vendor-neutral data.
Is Revit or Archicad better for openBIM? Both support IFC, BCF, and IDS. Archicad treats IFC as a core format and holds IFC4 export certification. Revit's IFC export improved in 2025 and 2026 but still shows documented friction with complex geometry. Archicad is generally the smoother openBIM experience for architectural work.
What does openBIM mean? openBIM is a way of working where building models and data move between tools in open, vendor-neutral standards, mainly IFC (ISO 16739-1:2024), BCF, and IDS, all defined by buildingSMART. It removes lock-in to any single file format.
Do I still need a separate tool for clash detection? For multi-discipline coordination, yes. A tool like Solibri federates IFC models from every discipline, runs model checking, and manages issues through BCF, which keeps coordination open rather than tied to one authoring platform.
Can I still buy a perpetual license in 2026? For most major tools, no. Archicad and Revit are subscription only. Vectorworks still offers perpetual licenses in some markets.
We sell Archicad and Solibri, so we will not pretend to be neutral. What we are is openBIM advocates, because open standards protect the one thing you cannot afford to lose: your data. The right tool is the one that fits your work and keeps your information yours.
