<p>The Rebar tool allows you to place <a rel="nofollow" class="external text" href="http://en.wikipedia.org/wiki/Rebar">reinforcing bars</a> inside <a href="Arch_Structure.html" title="Arch Structure">Arch Structure</a> objects. Rebar objects are based on 2D profiles such as <a href="Sketcher_Module.html" class="mw-redirect" title="Sketcher Module">sketches</a> or <a href="Draft_Module.html" title="Draft Module">draft objects</a>, that must be drawn on a face of a structure object. You can then adjust the configuration of the rebars, such as the number and diameter of the bars, or the offset distance between the two ends of the structural element.

</p><p>The above image shows a structural object, where two sketches are drawn, defining two bar diagrams. These two sketches are then turned into rebar objects.

<p>The Rebar tool has been greatly enhanced during the <a href="Google_Summer_of_Code.html" class="mw-redirect" title="Google Summer of Code">Google Summer of Code</a> 2017 edition. The result of that work is a series of new presets and wizards for the most common rebar types. They are packaged under an independent module called <b>Reinforcement</b>, that you can install via menu Tools -> Addons Manager. Once the Reinforcement addon is installed, on next run, FreeCAD will detect it and add a series of new tools under the Rebar button in the Arch toolbar and menu. The different tools from the Reinforcement Addon are described on the <a href="Arch_Workbench.html" class="mw-redirect" title="Arch Workbench">Arch Workbench</a> page.

<li> Adjust the desired properties (your rebar might not appear immediately, if some of the properties create an impossible situation, such as the bar diameter being 0, or the offset distances being bigger than the length of the structural element)</li></ol>

<h2><span class="mw-headline" id="Options">Options</span></h2>
|
|
<ul><li> Rebars share the common properties and behaviours of all <a href="Arch_Component.html" title="Arch Component">Arch Components</a></li>
|
|
<li> The rounding value is expressed in times the diameter. If your bar has a diameter of 5mm, a rounding value of 3 will create rounding at angles with a radius of 15mm.</li>
|
|
<li> Default values for new rebars can be set in the Arch preferences settings.</li>
|
|
<li> If a direction vector is not specified, the direction and distance along which the bars will spread is calculated automatically from the host structural object, by taking the normal direction of the base sketch, and taking its intersection with the structural object. If you specify a direction vector, the length of that vector will also be taken into account.</li>
|
|
<li> The spacing value is calculated from the current amount of bars, and represents the distance between the axes of each bar. You must therefore subtract the bar diameter to obtain the size of the free space between bars.</li></ul>

<p>The Rebar tool can by used in <a href="Macros.html" title="Macros">macros</a> and from the python console by using the following function:
|
|
</p>
|
|
<pre>makeRebar (structure,sketch,[diameter],[amount],[offset]) </pre>
|
|
<ul><li> Adds a Reinforcing Bar object to the given structural object, using the given sketch as profile.</li>
|
|
<li> If no diameter, amount or offset value is given, the default values from the Arch preferences settings are applied.</li>
|
|
<li> Returns the new Rebar object.</li></ul>
|
|
<p>Example:
|
|
</p>
|
|
<pre>import FreeCAD, Arch, Sketcher, PArt
|
|
struct = Arch.makeStructure(1,1,3)
|
|
sketch = FreeCAD.ActiveDocument.addObject('Sketcher::SketchObject','Sketch')
|
|
sketch.Support = (struct,["Face6"])
|
|
sketch.addGeometry(Part.Line(App.Vector(-0.4,0.4,0),App.Vector(0.4,0.4,0)))
|

Arch.makeRebar(structure,sketch) </pre>
