Standardization is key to error-free construction. The updated version includes a revamped bend library that adheres strictly to ACI 318-24 and Eurocode 2 EN 1992-1-1 updates.
EPTAR is a third-party ArchiCAD add-on for reinforcement detailing (rebar, concrete reinforcement). It is commonly used in regions following European standards (Eurocode 2, French DTU, etc.).
The “ArchiCAD 27 updated” version means the add-on has been recompiled/compatible with Graphisoft ArchiCAD 27 (released 2023/2024).
A standout improvement in this iteration is the user interface integration. Eptar Reinforcement now feels like a native part of Archicad 27 rather than an external plugin. The tool utilizes Archicad’s modern palette structures, making the learning curve shallow for existing Archicad users.
Furthermore, the update takes advantage of Archicad 27’s improved Attribute Management. Reinforcement attributes (such as steel grades and bar sizes) are now easier to manage and categorize, ensuring that schedules and material take-offs are accurate and BIM-compliant.
No software is perfect. The community has reported a few minor bugs in the initial release of EPTAR 27:
The release of Eptar Reinforcement for Archicad 27 is more than just a compatibility patch; it is a necessary evolution for modern BIM-based structural design. By stabilizing the toolset within Archicad 27’s advanced framework, Graphisoft and Eptar have ensured that professionals can upgrade their workflows without losing the ability to produce high-quality, data-rich reinforcement models.
For firms looking to streamline their BIM pipeline, updating to Eptar Reinforcement for Archicad 27 is a critical step in achieving a fully integrated structural documentation process.

The construction industry demands precision, speed, and seamless integration between architectural design and structural engineering. For architects and engineers using Graphisoft Archicad 27, the Eptar Reinforcement tool has long been a go-to solution for bridging the gap between 3D modeling and complex concrete reinforcement.
With the latest updates to Eptar Reinforcement for Archicad 27, users can experience a more streamlined, automated, and error-free workflow. This article covers the new features, why this update is a game-changer for BIM workflows, and how to get started. What is Eptar Reinforcement for Archicad? eptar reinforcement for archicad 27 updated
Eptar Reinforcement is a powerful add-on developed by Eptar, specifically designed to help Archicad users draw and define complex concrete reinforcement within their BIM models.
While Archicad is an industry leader in architectural design, detailing complex rebar structures natively can be time-consuming. Eptar Reinforcement solves this by providing dedicated tools to generate, calculate, and list reinforcement bars, meshes, and stirrups directly within the Archicad environment. What is New in the Updated Version for Archicad 27?
The updated version of Eptar Reinforcement for Archicad 27 brings several quality-of-life improvements, performance boosts, and feature enhancements designed to handle modern structural demands. 1. Enhanced Automation for Complex Geometries
The updated add-on features improved algorithms that better recognize complex architectural shapes. Whether you are dealing with slanted columns, curved walls, or non-orthogonal slabs, the tool can now automatically calculate and layout reinforcement meshes and stirrups with much higher precision. 2. Improved Interactive Schedules and Cutting Lists
One of the biggest strengths of Eptar Reinforcement is its ability to generate accurate schedules. In this update: Exporting bending schedules to Excel or PDF is faster.
Cutting lists now account for local manufacturing standards more accurately.
The connection between the 3D model and the schedules is more dynamic, instantly updating lists when a 3D element is modified. 3. Native Archicad 27 Optimization
This version is not just a port of the previous software. It has been rewritten to take full advantage of Archicad 27’s updated core, ensuring smoother panning, zooming, and editing in heavy 3D views. It minimizes lag when dealing with thousands of individual rebar elements. 4. Better Collaboration via BIMcloud and IFC
Structural engineers and architects often need to trade data. The updated Eptar Reinforcement ensures that all rebar elements carry the correct IFC properties when exported. This makes it incredibly easy to share reinforced concrete models with structural analysis software or external MEP collaborators via BIMcloud. Key Features You Should Be Using
If you are new to the add-on or simply looking to maximize your license, ensure you are utilizing these core functionalities:
Automatic Edge Detection: Place reinforcement in slabs and walls by simply clicking on the element. Standardization is key to error-free construction
Custom Stirrup Forms: Create custom shapes for unique structural columns and beams.
Mesh Placement: Easily define and place standard or custom welded wire reinforcement meshes.
Collision Detection: Use Archicad’s built-in collision detection alongside Eptar to ensure rebars do not clash with MEP systems or steel inserts. Why This Update Matters for BIM Workflows
In a traditional workflow, reinforcement detailing is often passed off to a specialist using a separate 2D CAD program. This creates massive fragmentation, leading to errors, lost data, and site delays.
By using the updated Eptar Reinforcement directly inside Archicad 27, you maintain a Single Source of Truth.
Accuracy: What you see in the 3D model is exactly what ends up in the schedule and on the construction site. Speed: Automated layouts save hundreds of drafting hours.
Design Coordination: You can check for physical clashes between rebars and plumbing or HVAC before breaking ground. How to Get the Update
To get your hands on the updated Eptar Reinforcement for Archicad 27, follow these steps:
Check Your License: If you have an active subscription or maintenance plan with Eptar, you may be entitled to a free upgrade.
Download the Installer: Visit the official Eptar website and navigate to the downloads section for Archicad 27.
Install and Load: Run the installer, and make sure to add the library and Add-On via Archicad’s Add-On Manager and Library Manager. The release of Eptar Reinforcement for Archicad 27
Update Your Templates: To make the most of it, update your office Archicad template to include the new Eptar schedules and object libraries.
If you are looking to take your structural detailing to the next level within a native BIM environment, the updated Eptar Reinforcement for Archicad 27 is an essential tool to add to your arsenal.
I couldn’t find a specific “deep paper” or official technical document titled exactly “EPTAR Reinforcement for ArchiCAD 27 Updated” in public or academic databases.
However, based on BIM and structural detailing workflows, here’s what this likely refers to — and where you can find the actual updated documentation:
Here’s where Eptar has always shined: beams with variable cross-sections, curved walls, sloped slabs, and complex intersections. The 2026 update (shipping with Archicad 27 support) introduces adaptive cover detection—meaning the rebar now automatically adjusts its position based on real geometric changes in the host element.
If you’ve ever manually repositioned rebars after a structural beam changes slope, you’ll appreciate this. It’s not just parametric; it’s geometry-aware.
To illustrate the power of the updated tool, let us walk through a typical use case.
Step 1: Model a concrete beam (300x600 mm) in Archicad 27 using the new "Structural Beam" tool.
Step 2: Select the beam, right-click, and choose Eptar > Automatic Reinforcement.
Step 3: In the dialogue, select:
Step 4: Click "Generate." The updated algorithm now places hooks automatically at the beam ends based on the cover settings defined in the Archicad 27 composite wall/column connections.
Step 5: Open the built-in Eptar Schedule palette. Notice that the bending schedule updates in real-time as you modify the beam length. You can now export this schedule directly to Excel with one click.
Step 6: Run Archicad 27’s Clash Detection. The updated Eptar rebars are recognized as "Structural Reinforcement" category, allowing you to ignore clashes between rebar and concrete formwork.
