In Archicad 27, the EPTAR interface allows users to define Reinforcement Configurations—essentially "favorites" for rebar types—allowing for rapid population of structural elements. Whether dealing with straight bars, stirrups, or complex shaped meshes, the tools allow for parametric control. The newest version of the add-on has been optimized to handle Archicad 27’s updated graphical processing, ensuring that even complex 3D reinforcement cages do not bog down the software’s performance. The visual feedback is immediate; engineers can see the 3D bars within the concrete elements in the 3D window, offering a level of spatial awareness that 2D sections simply cannot provide.

Developed by Éptár, a registered Graphisoft solution partner, this add-on integrates directly into Archicad. It allows users to place rebar, stirrups, and mesh configurations into architectural elements. The tool updates dynamically, meaning changes to the structural concrete geometry will automatically adjust the internal reinforcement layouts. Key Features in the Archicad 27 Version

Using the dedicated wall palette, users can place reinforcement meshes and rebar elements according to core structural engineering principles. The tool automatically accounts for window and door openings, shifting mesh grids and reinforcing edges without manual cutting. 📐 Free-Form and Polygon Rebars

Version 5.0 and newer (up to 6.1) introduced several refinements for modern Archicad workflows:

The Éptár Reinforcement add-on for Archicad 27 provides a dedicated solution. It enables architects and structural engineers to design, model, and document concrete reinforcement directly within the BIM environment. What is Éptár Reinforcement?

The scheduling capabilities are perhaps the most compelling argument for the software. A critical pain point in structural engineering is the quantification of materials. Manual calculation of rebar tonnage is prone to human error. EPTAR interacts with Archicad’s native Interactive Schedules to extract data directly from the model. Users can generate schedules listing bar marks, shapes, lengths, weights, and dimensions. If a bar is deleted or modified in the 3D model, the schedule updates instantly. This live link between the geometry and the data ensures that the Bill of Quantities (BOQ) is always accurate, providing contractors with precise material orders and reducing waste.

When the architect moves a wall or shortens a beam, the reinforcement updates automatically, saving hours of manual drafting.
