Arch Rebar Circular ColumnReinforcement

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

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



How to use
1. Select top face of a previously created object. 2. Then select  from the rebar tools. 3. A dialog box will pop-out on screen as shown below.



4. Select the Circular Column radio button in column reinforcement dialog.



5. Give inputs for data related to circular column reinforcement. 6. Click or  to generate circular column reinforcement.

7. Click to exit the dialog box.

Properties
Helical Rebars:
 * : The distance between rebar to the curved face.
 * : The distance between rebar from the top face of the structure.
 * : The distance between rebar from the bottom face of the structure.
 * : The pitch of a helix is the height of one complete helix turn, measured parallel to the axis of the helix.
 * : Diameter of the rebar.

Main Rebars:
 * : The distance between rebars from the top face of the structure.
 * : The distance between rebars from the bottom face of the structure.
 * : Diameter of the main rebars.
 * : The number of main rebars.
 * : The angular distance between ties.

Scripting
Arch API, Reinforcement API and FreeCAD Scripting Basics.

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

Create Circular Column Reinforcement

 * Creates a object from the given, which is an Arch Structure, and , which is a face of that structure.
 * If no nor  are given, it will take the user selected face as input.
 * ,, and are inner offset distances for the helical rebar with respect to the faces of the structure. They are respectively the side, top and bottom offsets.
 * is the parameter that determines how close or far apart each helical loop is to each other.
 * is the diameter of the helical rebar inside the structure.
 * and are inner offset distances for the main rebars with respect to the top and bottom faces of the structure, respectively.
 * is the diameter of the main rebars.
 * if it is it will create as many main rebars as given by ; if it is  it will create main rebars at an angle of, specified in degrees.
 * specifies the number of main rebars, or the value of the angle between the main rebars, depending on.

Edition of Circular Column Reinforcement
You can change the properties of the halical and main 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.
