Eptar Reinforcement For Archicad 27 -

This is a structured outline and a draft for a technical paper on EPTar Reinforcement for ArchiCAD 27. Since EPTar is a specialized plugin (often associated with advanced rebar detailing for European codes, particularly in precast and complex concrete elements), this paper is written as a practical technical overview.

Title:
Advanced Rebar Detailing and Automation: Implementing EPTar Reinforcement for ArchiCAD 27 This is a structured outline and a draft

Author: [Your Name/Firm Name]
Date: April 2026
Software Version: Graphisoft ArchiCAD 27 (Build 4001+) & EPTar 2024/2025 (Compatible with AC27) eptar reinforcement for archicad 27

1. Parametric Rebar Sets for Seismic Zones

ArchiCAD 27 improved its handling of IFC structural attributes. Eptar uses this to automatically differentiate between standard hook lengths, seismic crossties, and lap splices. You can now define a "Seismic Zone 4" preset, and Eptar will apply the ACI 318-19 or Eurocode 2 rules automatically to every beam and column.

1. The Setup (Installation & Licensing)

User: Structural BIM Manager
Action: Ensure ArchiCAD 27 (build 3001 or later) is installed. Download the matching Eptar Reinforcement version (e.g., 27.0.x) from the official Eptar portal. Install via the "Extensions & Add-Ons" manager.
Check: Activate license (USB dongle or network). Validate that the Eptar toolbar appears and the Eptar Settings dialog opens.

6. IFC 4.0 Export for Fabrication

A critical improvement in AC27 + EPTar is IFC 4.0 Reference View 1.2 support for reinforcement.

Native AC27 exports rebars as IfcReinforcingBar but may lose bending shape codes.
EPTar writes custom IfcPropertySet named “EPTar_BendingData” containing:
- ShapeCode (string)
- BendingDiagram (blob/URL)
- MachineFormat (BVBS/Unitechnik)

Validation: Tested export to Tekla Structures 2024 and Allplan 2025 – shape codes retained.
