Arch Rebar BeamReinforcement

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

This command is part of the Reinforcement Addon, that you can install with the Addon Manager via the menu.

The BeamReinforcement tool can be used in macros and from the Python console by using the following function:

Edition of Single Tie Four Rebars
You can change the properties of the ties and rebars with the following function


 * is a previously created group object.
 * The other parameters are the same as required by the function.
 * and may be omitted so that the rebar stays in the original structure.

Edition of Single Tie Multiple Rebars
You can change the properties of the ties and rebars with the following function


 * is a previously created group object.
 * The other parameters are the same as required by the function.
 * and may be omitted so that the reinforcement stays in the original structure.
