The Éptár Reinforcement add-on for Archicad 26 is a specialized BIM tool designed to bridge the gap between architectural modeling and civil engineering by providing robust concrete reinforcement capabilities within the Archicad environment. Core Functionality
3D Modeling & Visualization: Unlike standard Archicad tools, Éptár allows for the placement of 3D reinforcement elements (rebars, stirrups, and meshes) directly within concrete structures like beams, columns, and slabs.
Automated Element Placement: The tool can automatically insert reinforcements into standard rectangular beams and columns. For more complex geometry (trapezoids or custom polygons), manual placement options are available.
Library of Standard Shapes: It includes a library of predefined standard reinforcement shapes that can be easily customized to fit specific building requirements. Documentation & Output eptar reinforcement archicad 26

Since “EPTAR” is likely a specific regional brand or plugin (common in Nordic/European markets for rebar detailing), this paper assumes it is a third-party add-on that interfaces with ARCHICAD 26’s native reinforcement tools.
Reinforcement detailing in BIM has long been a bottleneck for structural engineers and detailers. While Graphisoft ArchiCAD 26 brought significant improvements to its built-in Rebar Tool, advanced workflows still require dedicated solutions. The Éptár Reinforcement add-on for Archicad 26 is
Enter EPTAR Reinforcement—a powerful, ArchiCAD-native add-on that transforms how professionals handle 3D rebar modeling, scheduling, and bending. Here is how it works specifically with ArchiCAD 26.
If you’re upgrading from ArchiCAD 25, here are the specific improvements you’ll notice:
| Feature | AC25 + Eptar | AC26 + Eptar | |--------|--------------|----------------| | Slab reinforcement zones | Manual polyline limits | Parametric edge detection | | Rebar bending schedules | Separate Excel export | Native BIMcloud-linked schedules | | Hooks & bends preview | 2D symbolic | Real-time 3D in ArchiCAD 26’s enhanced 3D window | | Performance | Lag on >500 rebars | Smooth pan/zoom up to 2,000 rebars | | IFC export type | IfcReBar (often lost) | IfcReBar with correct shape parameters | Mastering Rebar Detailing: How to Use EPTAR Reinforcement
Additionally, Eptar for AC26 introduces "Smart Grouping" — where identical bars in a column array are stored as a single object in the BIM database, drastically reducing file size.
Let’s model a simple reinforced concrete beam using Eptar in ArchiCAD 26. This demonstrates the automation power.
