For occasional beams and footings, native is fine. For daily structural detailing, Eptar pays for itself in a single project. Future Outlook: Eptar & ArchiCAD 27 (and beyond) While this article focuses on ArchiCAD 26 , Graphisoft has announced that Eptar will continue to be a strategic partner. Expect tighter integration with BIMcloud Saas and possibly AI-based optimization of rebar layouts to minimize cutting waste. eptar reinforcement archicad 26
This article provides a comprehensive guide to using , covering installation, new features, workflow optimizations, and troubleshooting. What is Eptar Reinforcement? For the uninitiated, Eptar Reinforcement is a third-party BIM extension developed by Cype Soft (in close collaboration with Graphisoft). Unlike ArchiCAD’s native rebar tools—which are powerful but require manual placement—Eptar automates the process. It interprets structural analysis results (often from Cype or other FEM software) and generates 3D reinforcement meshes directly inside ArchiCAD 26. Published: October 14, 2023 | Category: BIM &
| Feature | Native Rebar Tool | Eptar | |--------|----------------|-------| | Learning curve | Gentle | Steep but powerful | | Automatic beam reinforcement | No (manual each bar) | Yes (full cage in one click) | | Code-based spacing rules | Partial | Full (including seismic zones) | | Bar bending schedule | Basic table | Customizable to local standards | | Cost | Included in AC26 license | Additional license (approx. €600/year) | Expect tighter integration with BIMcloud Saas and possibly
Additionally, Eptar for AC26 introduces — where identical bars in a column array are stored as a single object in the BIM database, drastically reducing file size. Advanced Tips for Power Users 1. Custom Shapes via Python Eptar allows you to script complex rebar shapes (e.g., seismic hooks, U-bars). In ArchiCAD 26, the Python console ( Ctrl+Shift+P ) can now be used to define Eptar.Shape() classes. 2. Linking to Structural Analysis If you use Cype 2023, you can directly import a .csi or .cyp analysis file. Eptar will read the required reinforcement area (As,req) and automatically adjust bar sizing and spacing to meet it — no manual entry. 3. Template Workflows Save your Eptar settings as an .epl template. For a multi-story building, load the template on each floor’s beams. Maintains consistent cover, bar diameters, and hook angles. Common Issues & Fixes (Troubleshooting) "Eptar is not compatible with this version of ArchiCAD" Cause: You installed a version for AC24 or AC25. Fix: Download the Eptar 2023a for ArchiCAD 26 from the official Cype portal. Rebars disappear after moving a host beam Cause: Associativity is turned off. Fix: In Eptar Settings → Advanced → check "Maintain association with host" . Then use the Update Eptar Elements command after moving. Extremely slow regeneration on slabs Cause: Too many individual bars vs. bar sets. Fix: Use "Reinforcement Pattern" instead of "Explicit Bars" . AC26 handles patterns far better. Real-World Project: High-Rise Core Wall A recent case study from a Brazilian engineering firm used Eptar Reinforcement in ArchiCAD 26 to detail the shear walls and coupling beams of a 30-story tower.
or work with steel structures.
However, for professionals working in AC26 today, the Eptar workflow is mature, stable, and proven. Yes — if you are a structural engineer or BIM detailer handling concrete structures regularly.
