A week later, Elena presented The Hive to the city planning board. But instead of static renders, she used Archicad 27's new "Immersive Viewer" —a lightweight VR mode that ran on the board's laptops without special headsets.
She spun the model. The twisting facade glinted. She clicked a button labeled "Generate Change Log" , and a clean PDF appeared, showing every revision, every RFI response, and every structural approval—all tracked automatically by the software's built-in version control.
The board approved the project unanimously.
To understand the impact of Archicad 27, consider a real project: the "Horizon Tower" in Berlin, a 35-story residential and retail complex. archicad 27
In independent tests comparing Archicad 26 to Archicad 27:
| Feature | Archicad 27 | Revit 2025 | | :--- | :--- | :--- | | User Interface | Intuitive, context-sensitive palette | Ribbon-heavy, steeper learning curve | | File Size | Lighter (averages 30-50 MB per model) | Heavier (often 100-300 MB) | | Open BIM | Native IFC 4.3 champion | Requires extra plugins for full IFC fidelity | | Mac Support | Native Apple Silicon (M1/M2/M3) excellent | No native macOS version (Parallels only) | | Licensing | Perpetual / Subscription | Subscription only (higher annual cost) |
Verdict: Revit wins for large corporate ecosystems tied to Autodesk. Archicad 27 wins for design freedom, speed, and cross-platform teams (Mac/PC). A week later, Elena presented The Hive to
Archicad 27 continues Graphisoft’s push toward open BIM, design workflow automation, and visual clarity. Released in 2023, it bridges the gap between early concept design and detailed documentation. Below is a breakdown of its most impactful features.
| Component | Minimum | Recommended (Professional) | | :--- | :--- | :--- | | OS | Windows 11 / macOS Ventura | Windows 11 Pro / macOS Sonoma | | CPU | Intel Core i5 (12th gen) or AMD Ryzen 5 | Intel Core i7 (13th/14th gen) or AMD Ryzen 7/9 | | RAM | 16 GB | 32 GB (64 GB for complex models) | | GPU | 4 GB VRAM (DirectX 12 / Metal 3) | NVIDIA RTX 4060 or AMD Radeon Pro 8 GB+ | | Storage | 10 GB SSD (installation) | 1 TB NVMe SSD for project cache | | Display | 1920x1080 | 4K UHD (3840x2160) for dual monitors |
If you want to create a custom parametric object (e.g., a dynamic table or a configurable shelf), copy this code into a new object. This utilizes the improved Python API and GDL features in AC27. To understand the impact of Archicad 27, consider
How to use:
! --- PARAMETER DEFINITIONS (Add these in the Parameters List UI) ---
! a = Length (Real Number) - Default: 1.0
! b = Depth (Real Number) - Default: 0.3
! zzzyzx = Height (Real Number) - Default: 0.05
! matMain = Surface (Surface) - Default: Generic Wood
! --- MASTER SCRIPT ---
! Logic for parameter validation (New in AC27 allows stricter typing)
if a <= 0 then a = 1.0
if b <= 0 then b = 0.3
! --- 3D SCRIPT ---
! Use the new simplified attribute commands available in AC27
material matMain
! Draw the main body (A simple shelf board)
block a, b, zzzyzx
! Draw a parametric back lip
addz zzzyzx
block a, b/10, 0.05
del 1
! --- 2D SCRIPT (Plan View) ---
! Draw a simple line representation
line2 0, 0, a, 0
line2 a, 0, a, b
line2 a, b, 0, b
line2 0, b, 0, 0
! Hotspot for user interaction
hotspot 0, 0
hotspot a, 0
hotspot a, b
hotspot 0, b
Archicad 27 allows searching by any custom property (e.g., "Fire Rating = 90 minutes"). Save these searches as "Selection Sets" for rapid quality control.
