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 Two Ties Six Rebars

 * 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 tie elements with respect to the faces of the structure. They are respectively the left, right, top, bottom and front/rear offsets.
 * define the angle of the tip of the reinforcement loop of tie elements.
 * define the length of the tip of the reinforcement loop of tie elements, expressed in times the diameter of tie elements.
 * is the diameter of the tie elements.
 * if it is it will create as many two ties sets as given by ; if it is  it will create two ties sets separated by the numerical value of.
 * specifies the number of two ties sets, or the value of the separation between the sets, depending on.
 * is the diameter of the main rebars.
 * and are inner offset distances for the main rebars with respect to the top and bottom faces of the structure, respectively.
 * is the type of the main rebars; it can be or.
 * specifies the orientation of LShaped hook; it can be:, , , , , , or.
 * specifies direction for hook extension; it can be or.
 * is the parameter that determines the bending radius of the LShaped main rebars, expressed as times the diameter.
 * is the length of hook of LShaped rebars.
 * is the sequence of ties from top to bottom with respect to front view; it can be or.

Edition of Two Ties Six 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.
