Learn the basics of creating and editing reinforcement objects in AutoRebar, including how to set the working units for the model and the layout spaces.
  • Run the AutoRebar command to load the AutoRebar engine.
  • Run the Rebar command  to insert a new Rebar.
  • Type 20 for the diameter; Millimetres are the default units for both the model space and the bar diameter. Different units can be selected in Settings > Units.
  • Click a few points to define the vertices of the Rebar you want to create.
  • Stretch the Rebar to experience the way it reacts.
  • Double click it to modify the bar diameter, the annotation scale, the display modality (thin, thick or double line) and to hide/show the dimensions.
  • Insert a thread or a coupler at one of the ends.
  • Offset the bar to a specific concrete cover. The grip-points (the handles of the Rebar object) now lie on the concrete outline rather than the Rebar centreline, and the Rebar is offset to the specified concrete cover. The Rebar end can be also trimmed to respect the same cover.
It is important that the desired units for the model space be set at the beginning of a drawing. Other unit settings can be effectively changed at any later stage.
The mandrel diameter for a bent bar is a function of the bar diameter and is defined in AutoRebar Settings > Rebar > Bending Radius.
By default AutoRebar adopts the values for the bending criterion defined by Eurocode 2 UNI EN 1992-1-1 section 8.3 Permissible mandrel diameters for bent bars.
