Detailing including annotation, rebar resymbolization, and labeling of reinforcement is traditionally very time-consuming. First, there is the task of extending label lines. In complex reinforcement layouts, the time taken in just snapping to the appropriate main bar element is significant. Then, there is the task of including diameters, bar mark numbers, bar shape codes, and spacings etc. into label text. The same standard format is repeated over and over for every bar label, but the formatting time for each is still the same. When labels are placed, they must be updated whenever the concrete arrangement is changed. Label lines may require adjustment. Diameters, bar marks, and spacings might also need updating. Mistakes are easily made. Changes are often forgotten and perhaps only detected in the checking phase.

The 2D Rebar tools in OpenBridge Modeler eliminate these and other problems. Label lines are easily placed. Label text is automatically formatted. Reinforcement and schedule data is extracted directly from the reinforcing bar each label is attached to before inclusion in the text. Furthermore, Rebar maintains all labels once created. Label lines, text and included reinforcement parameters are automatically updated whenever the reinforcing arrangement is changed. All label dialog boxes include Bentley Rebar's unique Preset Text facility - a system designed to eliminate typing of label text.
