Arch Rebar Helical/pl

Description
The Helical Rebar tool allows the user to create a continuous helical reinforcing bar inside an Arch Structure object.

The Helical Rebar tool is also integrated into BIM Workbench.

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

Usage

 * 1) Select any face of a previously created  object.
 * 2) Then select  from the rebar tools.
 * 3) A task panel will pop-out on the left side of the screen as shown below.
 * 4) Select the desired orientation.
 * 5) Populate the inputs like 'Left Cover', 'Right Cover', 'Top Cover', 'Bottom Cover', 'Front Cover', 'Bent Angle', 'Bent Factor', 'Rounding' and 'Diameter' of the rebar.
 * 6) Select the mode of distribution either 'Amount' or 'Spacing'.
 * 7) * If 'Spacing' is selected, a user can also opt for custom spacing.
 * 8)  is used to verify or change the face for rebar distribution.
 * 9) Click  or  to generate the rebars.
 * 10) Click  to exit the task panel.



Properties

 * : 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.

Scripting
Arch API, Reinforcement API and FreeCAD Scripting Basics.

The Helical Rebar 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 rebar with respect to the faces of the structure. They are respectively the side, bottom, and top offsets.
 * is the diameter of the reinforcement spiral inside the structure.
 * is the parameter that determines how close or far apart each spiral loop is to each other.

Edition of the 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.
