Arch Rebar 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 any 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 desired type of column reinforcement. 5. Give inputs for data related to ties. 6. Click next and dialog box will be updated as shown below.

7. Select desired rebar type and fill data for main rebars. 8. Click next and dialog box will be updated as shown below.

9. Select desired rebar type and fill data for xdirection rebars. 10. Click next and dialog box will be updated as shown below.

11. Select desired rebar type and fill data for ydirection rebars. 12. Click or  to generate column reinforcement. 13. Click to exit the dialog box.

Properties
Ties:
 * : The distance between the left end of the tie to the left face of the structure.
 * : The distance between the right end of the tie to right face of the structure.
 * : The distance between tie from the top face of the structure.
 * : The distance between tie from the bottom face of the structure.
 * : The distance between tie from the top/bottom face of the structure.
 * : The number of ties.
 * : The distance between the axes of each tie.

Tie1:
 * : Diameter of the tie.
 * : Bent angle defines the angle at the ends of a tie.
 * : Extension Factor defines length of end of tie, expressed in times the diameter.

Main Rebars: Rebars present at corners of tie
 * : Type of main rebars.
 * : Orientation of LShaped hooks.
 * : Direction for hook extension.
 * : Length of hook of LShape rebars.
 * : A rounding value to be applied to the corners of the LShape rebars, expressed in times the diameter.
 * : The distance between rebar from the top face of the structure.
 * : The distance between rebar from the bottom face of the structure.
 * : Diameter of the main rebars.

XDir Secondary Rebars: Rebars along x-direction except main rebars
 * : Type of x-direction rebars.
 * : Orientation of LShaped hooks.
 * : Length of hook of LShape rebars.
 * : A rounding value to be applied to the corners of the LShape rebars, expressed in times the diameter.
 * : The distance between rebar from the top face of the structure.
 * : The distance between rebar from the bottom face of the structure.
 * : Number#Diameter set of the x-direction rebars.

YDir Secondary Rebars: Rebars along y-direction except main rebars
 * : Type of y-direction rebars.
 * : Orientation of LShaped hooks.
 * : Length of hook of LShape rebars.
 * : A rounding value to be applied to the corners of the LShape rebars, expressed in times the diameter.
 * : The distance between rebar from the top face of the structure.
 * : The distance between rebar from the bottom face of the structure.
 * : Number#Diameter set of the y-direction rebars.

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:


 * 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.
 * define the length of the tip of the reinforcement loop, expressed in times the diameter.
 * is the diameter of the ties.
 * if it is it will create as many ties as given by ; if it is  it will create ties separated by the numerical value of.
 * specifies the number of ties, or the value of the separation between them, 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 "StraightRebar" or "LShapeRebar".


 * is the diameter of the reinforcement bars inside the structure.
 * if it is it will create as many reinforcement bars as given by ; if it is  it will create reinforcement bars separated by the numerical value of.
 * specifies the number of reinforcement bars, or the value of the separation between them, depending on.
 * specifies the orientation of the rebar; it can be or.

Depending on the orientation of the rebar, the function can be called in two general ways by setting appropriately.

The rebar is horizontal

 * is a tuple with either a or a  offset.
 * In this case refers to the  offset, and  refers to the  offset.

The rebar is vertical

 * is a tuple with either a or a  offset.
 * In this case refers to the  offset, and  refers to the  offset.

Edition of rebar
You can change the properties of the rebar with the following function


 * is a previously created 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.
