Probar 2D (formerly AutoPadds) is an extension for AutoCAD® that turns it into a full-featured reinforced concrete detailing system. Probar 2D offers almost identical functionality to Padds but in the AutoCAD® environment. (Padds is a CAD and detailing module that forms part of PROKON® Structural Analysis and Design.)

AutoPadds Toolbar

With Probar 2D, you can detail reinforcement directly in AutoCAD®. You can open Padds drawings and work with bending schedules generated by the PROKON®concrete design modules. You can also link reinforcement layouts created with Probar 2D into your Revit® model.

Probar 2D Features

Probar 2D is an extension for AutoCAD® with reinforcement detailing functionality similar to that of Padds. Probar 2D complements and extends the reinforcement functionality of Revit®.

AutoPadds Bending Schedule PaletteReinforcement Shape Codes

With Probar 2D, you can create your own libraries of reinforcement shape codes. Shape codes for the following codes of practice are included by default:

  • BS 4466 - 1989
  • BS 8666 - 2005
  • SANS 282 - 2004

Rebar Properties Palette

Probar 2D has a properties palette for rebar objects (similar to other AutoCad® object such as lines and circles) for easy editing of rebar properties such as diameter, shape code and dimensions. And like other objects, rebar objects can be filtered out of a multiple object selection by selecting type “Rebar” from the type dropdown at the top of the properties palette.

Schedule Palette

Probar 2D has a scheduling calculator is contained in a AutoCAD® docking palette, making it easy to access. The palette's purpose is to read all the rebar objects in the drawing, help you sort the information, and output it in tables on the AutoCAD® drawing.

Using AutoCAD® in conjunction with Revit®

The fact that building contractors prefer working with simple 2D reinforcement placing diagrams, suggests 2D reinforcement detailing will remain the preferred technique for the foreseeable future. For this reason, AutoCAD® Revit® is currently marketed as "suite" that includes AutoCAD® — reinforcement and other 2D detailing tasks are typically performed in AutoCAD® and the drawings linked back to Revit®. To use Probar 2D for detailing reinforcement in conjunction with a Revit® model:

  • Build the model in Revit®.
  • Use the Export function to export a slab or floor layout to CAD format.
  • Open the exported drawing in AutoCAD®, and use the Probar 2D functions to detail the slab.
  • In Revit®, use the Import function on the File menu to import the CAD drawing into the model.

Once linked this way, any changes made in the AutoCAD® drawing (including rebar changes made using Probar 2D) will automatically reflect in the Revit® model.


To install or upgrade Probar 2D:

  1. Click the link alongside to download the setup package to your computer's hard drive.
  2. Double-click the downloaed file launch the setup utility and follow the prompts.

Note: You need a valid license in order to use Probar 2D. If you wish to try out Probar 2D, please contact us for a trial license.

System requirements

  • Minimum: AutoCAD® 2019 64-bit or later
    Recommended: AutoCAD® 2021 64-bit
  • Minimum:Windows 7 64-bit on a PC with 8 GB RAM and 1920 x 1080 WUXGA display
    Recommended: Windows 10 Professional edition 64-bit on a PC with 16 GB RAM

Compatibility notes:

  • Probar 2D cannot be installed as an extension for AutoCAD® LT due to limitations of that program; the full version of AutoCAD® is required. Using object enablers, you can use AutoCAD® LT to view (but not edit) rebar objects created with the full version of AutoCAD® and Probar 2D.
  • Probar 2D is NOT compatible with Windows 10 in S Mode.
