Eptar Reinforcement For Archicad 27 ●
Eptar Reinforcement for Archicad 27 is a specialized BIM add-on designed for architects and civil engineers to create detailed 3D reinforcement models and 2D documentation within the Archicad environment. It
automates the placement of rebars, stirrups, and mesh, while providing tools for precise structural detailing and quantity take-offs Core Functionalities Automated Element Placement
: Automatically inserts reinforcements into standard structural elements like rectangular beams and columns. It also supports complex forms such as crowns and slanted walls cropped to roofs. Dynamic 3D Modeling
: Users can place and check the positioning of rebars and meshes in a full 3D view to identify potential collisions or design errors before construction. Intelligent Documentation : Generates comprehensive Cutting Lists
(Iron Lists) that include rebar IDs, lengths, diameters, and total weights, which can be placed directly on floor plans as interactive tables. Customizable Reinforcement
: While standard shapes are preset, the tool allows for manual definition of custom polygonal rebar forms, stirrup groups, and spiral stirrups. Key Features for Archicad 27 EPTAR REINFORCEMENT 4.0 | Tutorial
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
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
Key Capabilities
- Parametric bar and mesh families for beams, slabs, walls, columns, footings.
- Automatic bar distribution, hooks, bends, anchorage, lap/splice definitions.
- Reinforcement view filters and 2D/3D representation control.
- Rebar tagging, schedules, weight and cut-length reports.
- Integration with ARCHICAD’s IFC export and native geometry for coordination.
- Export to industry formats (IFC4, CIS/2, CSV, specialized CNC/production formats) depending on Eptar’s available exporters.
- Clash detection support when combined with BIM coordination tools.
5. Quantity Takeoff & Scheduling
EPTar generates two schedule types:
| Schedule Type | Data Output | AC27 Native Equivalent | |---------------|-------------|------------------------| | Bending list | Shape code, bar length, diameter, weight, total qty | Not directly available | | Material summary | Steel grade (B500B), total kg per element, center of gravity | Partial (no grade) |
Export to Excel: Right-click schedule → “Export to XLSX” → Pre-filled bending machine columns.
Step 4 – Schedule & Marking
- Use
Document→Schedules→Rebar Schedule(automatic table with bending diagram). - Add Rebar Mark labels in section/elevation.
Learning Resources & Next Steps
- Install and test Eptar on a sample project to establish templates.
- Create a small-sheet detailing set (one slab plan, one beam detail, bending schedule) to validate workflows and exports.
- Coordinate with fabricator to confirm NC/bending schedule format and conventions.
If you want, I can:
- Produce an ARCHICAD-27-specific template (layers, rebar styles, schedule columns) ready to import, or
- Create a step-by-step sample workflow for a particular element type (slab, beam, wall) with parameter values and screenshots.
In the high-stakes world of structural engineering, Elias Thorne
was known for two things: his obsession with precision and his deep-seated dread of revision days. For years, Elias had navigated the complex geometries of modern architecture using Archicad, but the transition from a beautiful design to a constructible, reinforced reality was always where the "magic" met a grinding halt.
Then came the mandate for the Aethelgard Pavilion—a structure defined by sweeping, organic concrete curves that defied standard logic.
"We need the rebar schedules by Friday," his lead architect had said, "and Elias, the geometry is... unconventional."
Elias opened Archicad 27, the latest version of his digital drafting home. He knew that for a project this complex, manual detailing would be a descent into madness. He turned to his secret weapon: ÉPTÁR Reinforcement. The Awakening of the Mesh Eptar Reinforcement for Archicad 27 is a specialized
As Elias activated the ÉPTÁR add-on, the interface shifted. It wasn't just about drawing lines anymore; it was about defining the DNA of the concrete. He started with the foundation—a massive, sloping slab. With a few clicks, the Automatic Reinforcement tool scanned the Archicad elements.
In a shimmering display of digital alchemy, the software calculated the necessary mesh. Steel bars began to weave themselves into the 3D model, hugging the curves of the Pavilion like a metallic skeleton. What used to take hours of painstaking calculation was happening in heartbeats. The Beauty of the "Complex"
The real test was the Pavilion’s central column—a twisting, fluted pillar that looked more like a frozen whirlwind than a support structure. Standard tools would have buckled. But Elias utilized the Reinforcement of Objects feature.
He defined the stirrups and the longitudinal bars, watching as ÉPTÁR's algorithms respected the tapering edges of the Archicad 27 3D mesh. He rotated the model, marveling at the lack of collisions. The steel was dense, calculated, and perfectly aligned with the structural requirements. The Final Validation
Friday arrived. The lead architect walked into Elias’s office, expecting to see a man buried under piles of red-inked corrections. Instead, Elias was leaning back, sipping a coffee. "The schedules?" the architect asked.
Elias tapped a key. The Listing tool in ÉPTÁR instantly generated a comprehensive Cutting List and Weight Report. Every bar, every bend, and every kilogram of steel was accounted for, extracted directly from the 3D model without a single manual entry error.
"It’s all here," Elias said, pointing to the screen. "Every curve is reinforced, and every schedule is ready for the fabricator." Aethelgard Pavilion
wouldn't just be a dream in a computer; it was now a blueprint for reality. Thanks to the synergy between Archicad 27 and ÉPTÁR, the impossible geometry had found its backbone.
The Éptár Reinforcement add-on for Archicad 27 bridges the gap between architectural modeling and civil engineering by providing specialized tools to design, document, and quantify steel reinforcement directly within the BIM environment. Core Capabilities Key Capabilities
The tool allows you to move from 2D schematic drawings to a complete 3D reinforcement skeleton without leaving Archicad.
Automated Element Placement: Automatically generates rebars and stirrups for standard rectangular beams and columns.
Complex Geometries: Supports manual placement and "Polygon" style rebars for non-rectangular sections (trapezoids, arcs, or custom shapes).
3D Verification: Enables users to visualize the rebar cage in 3D to check for collisions or placement errors before finalizing documentation.
Library Management: Most elements are handled as intelligent objects within the Éptár Reinforcement Library, allowing for detailed parameter adjustments. Documentation & Reporting
The primary output of the add-on is the generation of precise technical data for construction.
Cutting Lists: Generates tables listing every component by ID, length, and diameter.
Automatic Quantity Takeoffs: Summarizes the total weight and count of rebar used in the project, which is critical for cost estimation.
Integrated Views: You can create dedicated "Reinforcement Plans" by adjusting floor plan cut planes to display specific structural levels clearly. Usage Considerations It is possible to drawing Reinforced Concrete with ArchiCAD
3. Activation
- Look for an Eptar toolbar or menu under
Options→Reinforcement. - Enter license key (usually USB dongle or online activation).
Step 5: Manual Adjustments (The "Drag" Feature)
If you need a specialty bar (e.g., a U-bar starter), use the Eptar Custom Bar tool. Click on the face of the concrete, specify the two anchor points (face to face), and Eptar calculates the unfolded length instantly. ArchiCAD 27’s enhanced snap guides make this feel like drawing a line.
