ArchiCAD 26 introduced enhanced parametric rebar sets and improved IFC4 reference handling. However, for complex codes (ACI, EC2, BS, etc.) and automated shop drawings, EPTAR bridges the gap by offering:
Outdated installers are the #1 cause of "Eptar not showing up" forum posts. Follow these steps carefully:
The integration of EPTAR into an Archicad 26 workflow generally follows this process: eptar reinforcement archicad 26
(If you want, I can create a sample reinforcement preset for Archicad 26 or a template bar schedule layout — tell me which element type: slab, beam, column, or wall.)

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.
However, for professionals working in AC26 today, the Eptar workflow is mature, stable, and proven. ArchiCAD 26 introduced enhanced parametric rebar sets and
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 | While this article focuses on ArchiCAD 26 ,
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.
Go to Design > Clash Detection (ArchiCAD native). Add the "Eptar Rebar" layer set. Run against MEP ducts or architectural columns. Eptar bars are recognized as solid geometry — clashes appear in bright red.
