AutoCAD Rebar Tool
AutoCAD Rebar Tool

This tool was developed to provide AutoCAD 3D rebar functionality for modelling rebar cages to BS-8666 standards and for generating bending schedules. To learn more about the tool, watch the Overview Video below.

Conformance to standard BS-8666 Shape Codes

Overview Video


The requirement for this tool comes from a customer request. The customer in question is responsible for designing rebar cages for pile caps and they are AutoCAD customer without the need for a full structural application. They only need to use a limited number of the standard UK BS-8666 Shape Codes but they need the ability to model and edit the bars and so then create Bending Schedules.

  • Supported Standard Shape Codes are: 00, 01, 11, 26, 34, 51, 77

  • supported Custom Shape Codes are: 99-1 (Helix with top and bottom "triple turns") & 99-2 (a separate "triple turn" that can be combined with a standard Helix)
  • Calculated bar lengths and weights.

  • Dimension checks set out in Table 2 of BS-8666.

  • Bending Schedule as an AutoCAD Table.

  • Bending Schedule exported to an Excel Spreadsheet.

Technical Details

Whilst the tool itself is of course a useful application, it also helps to demonstrate the following capabilities that can be repurposed for other tools, for example:

  • Modelling complex 3D solid geometry that is saved to standard AutoCAD Blocks with meta-data that enable the geometry or data to be edited without having to deal with custom entities and object enablers.

  • Extracting information into an AutoCAD Table within the drawing.

  • Exporting information out to an Excel Spreadsheet.

The tool is built for compatibility with AutoCAD 2021 and AutoCAD 2022 - if you require an earlier version, let me know and I'll see what I can do.
