AutoRebar 2026 (for AutoCAD 2027 Detailing Guide)

Overview of AutoRebar 2026 for AutoCAD 2027

AutoRebar is a powerful reinforced concrete detailing software developed by Paolo Locatelli. It acts as an intuitive plugin, adding a dedicated toolbar of specialized objects to Autodesk AutoCAD and all its vertical products (including AutoCAD Architecture, MEP, and Civil 3D) . The latest version, 2026 v3.4.2, is fully compatible with AutoCAD 2027, representing a significant leap in smart reinforcement detailing .

The primary purpose of this rebar detailing software is to streamline the creation of complex reinforcement details. By moving away from manual, error-prone 2D drafting, AutoRebar introduces dynamic objects like intelligent Rebars and Crosshairs. This allows structural engineers, detailers, and fabricators to achieve significant productivity gains in just hours. If you can navigate AutoCAD, the learning curve for AutoRebar is designed to be remarkably short .

Key Features

AutoRebar is packed with features that transform how you work with concrete detailing. Here are its core capabilities:

A Comprehensive Object Library

The software equips you with a dedicated set of tools for every type of reinforcement element. This library allows for the quick creation of standard and complex shapes:

• Rebars & Shapes: Create dynamic Rebars that behave like polylines, complete with hooks and custom bends. This includes specialized tools for Stirrups, Crossties, Loops (circular stirrups), Spirals, and Chairs .

• Crosshairs: Insert precise cross-section representations of rebar. These can be arranged in linear, circular, or arc patterns for a clear visual representation of reinforcement layout .

• Annotation & Scheduling: Generate Marks (for scheduling and quantity takeoff) and Callouts (for dynamic annotations not used in scheduling). These elements are intelligently linked to the rebars they reference .

Dynamic Linking and Automatic Updates

This is a cornerstone feature that sets AutoRebar apart for productivity:

• Intelligent Updates: All AutoRebar elements are dynamically linked. When you modify a rebar’s geometry, all associated Marks, Callouts, and even the Bar Bending Schedule update automatically and in real-time. This eliminates the need for manual adjustments and significantly reduces the risk of errors .

• Zero Errors: The dynamic nature of the objects ensures consistency across your project, preventing discrepancies between drawings and schedules.

Automated Bar Bending Schedules (BBS)

One of the most powerful features is the ability to generate professional, accurate Bar Bending Schedules automatically:

• Effortless Generation: Create a comprehensive BBS directly within your AutoCAD drawing or export it to Excel (CSV format) with a single click .

• Schedule by Selection: You are not limited to creating schedules for the entire project. The selBBS command allows you to generate a schedule only for a selected set of structural elements .

• Smart Quantity Takeoff: The BarList command exports detailed quantity takeoff data directly to a CSV file for further analysis .

Complete Customization

The software is designed to fit seamlessly into your existing workflow and standards:

• Customizable Terminology: The Dictionary Tool is a unique feature that gives you complete control over the technical terminology used by the software. You can define specific symbols, terms, and sentences for each component, allowing you to produce drawings in any language and according to your company’s specific style guide .

• Flexible Formatting: You can fully customize the format of Marks and the layout of Bar Bending Schedules to match your project or company requirements .

• Layer and Color Controls: Customize the default layer names and colors for all AutoRebar objects and their sub-objects, ensuring consistency with your existing CAD standards .

• Unit and Precision Settings: Options are stored on a per-drawing basis, allowing you to manage units, digit preferences, and display formats (metric or imperial) independently for each project .

What’s New in AutoRebar 2026 v3.4.2

The latest version, v3.4.2, released on March 25, 2026, focuses on compatibility and stability :

• AutoCAD 2027 Compatibility: This is the headline feature, ensuring that the plugin works flawlessly with the newest version of Autodesk’s flagship software .

• Callout Command Fix: The Callout command has been renamed to Callout_. This critical fix prevents a conflict with a hidden command in AutoCAD’s Sheet Set Manager, which was causing errors for some users .

• Bug Fix: A fix was implemented to resolve a minor rounding error that could occur for bar spacing under certain specific conditions, improving the accuracy of your detailing .

System Requirements

Before installing, ensure your system meets the following requirements:

• Supported Software: AutoRebar 2026 v3.4.2 is fully compatible with Autodesk AutoCAD 2027 and all its vertical products (e.g., AutoCAD Architecture, AutoCAD MEP, Civil 3D) .

How to Use the Software: A Step-by-Step Guide

Getting started with AutoRebar is designed to be intuitive. Here is a basic workflow to create a reinforcement detail:

1. Load the Plugin: Click the AutoRebar icon on your toolbar. This loads the plugin and makes the dynamic objects visible .

2. Create a Rebar: Use the Rebar command. This behaves similarly to the standard Polyline command. Specify the diameter and follow the command line options to draw the rebar’s path, including arcs and hooks .

3. Create a Stirrup: For faster detailing, use the Stirrup command. Specify the diameter, the concrete cover, and the two opposite corners of the rectangular concrete section. AutoRebar will automatically generate the stirrup .

4. Add a Mark: Use the Mark command to assign a mark number to your rebar or group of bars. This links the rebar to the scheduling system .

5. Generate a BBS: Once you have created your rebars and marks, use the BBS command. AutoRebar will generate the Bar Bending Schedule, which you can insert into your drawing or export as a CSV file .
