Reinforcement

Description

The Reinforcement ColumnRebars tool allows the user to create reinforcing bars inside a Column Arch Structure object.

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

Three usage examples are available:

• Single tie rectangular column (see below)
• Two ties six rebars rectangular column
• Circular column

Single tie reinforcement inside a column

Usage

1. Select any face of a previously created Arch Structure object.

2. Then select Column Reinforcement from the rebar tools.

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