Reinforcement

Описание

The Reinforcement BarBendingSchedule tool allows the user to create the bar bending schedule of reinforcing bars.

This tool is part of the Reinforcement Workbench, an external workbench that can be installed with the Addon Manager.

Bar Bending Schedule of reinforcing bars

Применение

1. Select Rebar and Rebar2 objects you want to include in Bar Bending Schedule. Or select Structure objects to include Rebar and Rebar2 objects hosted by those into Bar Bending Schedule. If nothing is selected, then Bar Bending Schedule will be generated for all Rebar and Rebar2 objects present in the model.

2. Then select Bar Bending Schedule from the rebar tools.

3. A dialog box will pop-out on the screen as shown below.

Dialog Box for the Reinforcement Bar Bending Schedule tool

4. Modify data to suit your requirements.

5. Click OK or Apply to generate Bar Bending Schedule for rebars.

6. Click Cancel to exit the dialog box.

• Generates and returns a bar bending schedule SVG element for given rebar_objects.
• rebar_objects is a list of <ArchRebar._Rebar> or <rebar2.BaseRebar> objects, to generate their bar bending schedule. If not provided, then all ArchRebars and rebar2.BaseRebar objects with unique Mark from ActiveDocument will be selected.
