Archicad 27, released in September 2023, introduced significant enhancements focused on design flexibility, multidisciplinary collaboration, and workflow efficiency. As a mature BIM software, it remains a central tool for architects, though it has since been succeeded by newer versions like Archicad 28 and 29. Core New Features
Design Options: A native tool that allows users to create and manage multiple design variations within a single project file. It includes a dedicated palette for toggling between options and sets.
Integrated MEP Modeler: The MEP (Mechanical, Electrical, Plumbing) toolset was completely overhauled to be part of the core Archicad environment. Updates like version 27.2.0 added features such as Offset Segment, Associative Dimensioning, and improved interactive schedules for MEP elements.
Distance Guides: A new interaction feature that provides real-time visual feedback on distances while placing or moving elements, aimed at speeding up the initial drafting process.
AR/VR Visualization: Improved connectivity with external visualization tools like Enscape and Twinmotion, alongside enhancements to the built-in BIMx mobile viewer. Interoperability and Collaboration

Archicad 27 , "paper" typically refers to Paper Size settings within the Layout Book
, which determine the physical or digital dimensions of your architectural drawings. Core Paper Concepts in Archicad 27 Paper Size vs. Model Size Paper Size (Scale-independent)
: Elements like text or fills set to "Paper size" will maintain a fixed size on the sheet (e.g., 2mm high) regardless of the drawing's scale. Model Size (Scale with plan)
: Elements will grow or shrink relative to the model when you change the drawing scale. Printable Area : In the Layout Editor, the white area represents the usable print area, while the shows non-printing margins. Master Layouts
: This is where you define the standard paper sizes (A1, A3, etc.) for your project. Any layout assigned to a Master will inherit its paper dimensions and margins. Graphisoft Community How to Adjust Paper Settings Drawing placed on master layout not clipping properly
Elena stared at the screen, her coffee going cold for the third time that morning. She was a principal architect at Veridian Dynamics, a mid-sized firm known for sustainable housing. But today, she wasn't designing a net-zero home. She was wrestling with a dinosaur.
The project was "The Hive," a mixed-use building with a twisting, organic facade. In her old software—let's call it "LegacyCAD"—every curved panel was a nightmare of exploded solids and orphaned lines. She had spent two weeks just trying to get the curtain wall to look right, let alone be accurate for the structural engineer.
Her junior architect, Miguel, poked his head in. "Elena? The contractor just sent over the RFI. They say our section details don't match the 3D model export from last week."
Elena groaned. "Another coordination headache. I'll fix the lines manually."
"Or," Miguel said, sliding a fresh USB drive onto her desk, "we could stop fighting ghosts. IT pushed Archicad 27 to everyone last night. I've been testing it."
Elena was skeptical. New software meant a learning curve, lost productivity, and the usual "where did that button go?" frustration. But the deadline for The Hive was in six weeks, and LegacyCAD was failing her.
"Fine," she sighed. "Show me."
Miguel pulled up a chair and opened Archicad 27. The interface looked familiar but cleaner. He opened The Hive’s file—which had taken an hour to import—and clicked on the problematic twisting facade.
"Watch this," he said. He opened the new Curtain Wall tool. But this wasn't the old Curtain Wall. This was Archicad 27's redesigned system.
Instead of manually placing millions of mullions, Miguel right-clicked and selected "Pattern Sequence by Distance." He drew a single curved guide line along the facade's spine. Instantly, the entire grid of panels adjusted itself, compressing and expanding the spacing naturally around the building's tightest curves. archicad 27
Elena leaned forward. "That... that would have taken me three days."
"That's not even the good part," Miguel grinned. He selected a single distorted panel. A new palette appeared: "Direct Element Editing." He grabbed a corner node and pulled. The panel twisted organically, like origami. A real-time overlay showed the exact angle, deformation, and glass stress factors.
"How is the schedule tracking that?" Elena asked, stunned.
"Automatically," Miguel said. He clicked a new icon in the corner—"Open BIM Collaboration"—and a split screen appeared. On the left was their Archicad model. On the right was the structural engineer's Revit file, updated live from the cloud. As Miguel twisted the panel, a yellow highlight appeared on the Revit side, showing the exact steel connection point automatically adjusting.
Elena sat back. Her coffee was still warm. For the first time in weeks, she felt a glimmer of hope, not panic.
If "a piece" means a starting point for a project, Archicad 27 focuses heavily on Classification Systems and Renovation Filters. Here is the recommended structure for a standard AC27 Project Info setup:
Archicad 27 is a release defined by stability and intelligence. It resists the urge to add flashy, gimmicky features in favor of fixing the pain points that architects face daily. It acknowledges that the future of architecture isn't just about drawing walls, but about managing data, collaborating securely, and documenting with absolute precision.
For firms entrenched in the Graphisoft ecosystem, Archicad 27 offers the peace of mind that their backbone is stronger than ever. For those on the fence, it serves as a reminder that BIM software can be powerful without sacrificing the art of design. It is the "Architect’s BIM," all grown up.
Archicad 27, released by Graphisoft in late 2023, is widely considered one of the most significant updates to the BIM software in a decade. It introduced transformative tools like Design Options and integrated AI visualization, focusing on streamlining the creative workflow and enhancing interoperability with other industry-standard software. 1. Key Feature: Design Options
The most celebrated addition in Archicad 27 is the dedicated Design Options tool.
Purpose: It allows architects to explore and manage multiple design variations within a single project file without the need for complex layer workarounds or maintaining multiple separate files.
Efficiency: Users can easily switch between different layouts (e.g., different room configurations or facade designs) to present to clients, significantly reducing the "hassle" of previous manual workflows. 2. AI-Powered Visualization
Graphisoft integrated the Archicad AI Visualizer, a tool powered by Stable Diffusion, to assist in early-stage design.
Generative Design: Architects can create basic 3D concept models and use simple text prompts (e.g., "modern office with wood surfaces") to generate high-quality, photorealistic imagery.
Privacy: Because source images and processing are handled locally on the user's hardware (requiring NVIDIA GPUs or Apple Silicon), intellectual property remains fully protected. 3. Enhanced Interoperability & Connectivity
Archicad 27 improved its ability to communicate with rival software and other disciplines:
Revit Connectivity: The update features optimized file sharing with Revit 2024. This includes an IFC Model Exchange Tool and the ability to import RFA-based family files directly as native Archicad objects.
FBX Support: New support for FBX files allows for better data exchange with external rendering engines and AR/VR applications. 4. Visualization & Rendering Improvements
Beyond AI, the software's native rendering capabilities received a boost:
Physically Based Rendering (PBR): Delivers more realistic textures and lighting by simulating how light naturally interacts with material properties, resulting in softer, more lifelike shadows.
BIMx Improvements: Archicad 27 continues to leverage BIMx for mobile and web-based model viewing, making it easier for clients to explore designs interactively. 5. Comparison with Competitors Feature Archicad 27 Autodesk Revit Learning Curve Generally considered gentler and more intuitive. Steeper; mastering parametric families takes more time. Platform Native support for both macOS and Windows. Primary support for Windows only. Project Size Known for handling large project files with relative ease. Can become heavy or slower with extremely large files.
For those looking to try the software, Graphisoft offers a Demo Mode and educational licenses for students and educators. Archicad 27 and beyond - BTC Articles
