説明

Rebarツールを使用すると、Arch Structureオブジェクトの中に reinforcing bars を配置することができます。 Rebarオブジェクトは、sketches /スケッチやdraft objects/ドラフトオブジェクトなどの2Dプロファイルに基づいており、構造オブジェクトの面に描画する必要があります。バーの数や直径、または構造要素の両端のオフセット距離など、リバーの構成を調整することができます。

Rebar objects are based on 2D profiles such as Draft objects and Sketches, that must be drawn on a face of the structural object. After creation you can adjust the properties of the rebar, including the number and diameter of the bars, and the offset distance between them and the faces of the structural element.

上の図は、2つの棒グラフを定義する2つのスケッチが描かれている構造オブジェクトを示しています。これらの2つのスケッチは、鉄筋オブジェクトに変換されます。

使用方法

Switch to the BIM Workbench
Create an Arch Structure element.
Switch to the Sketcher Workbench.
Select one face of the structural element.
Press the New Sketch button to start a new sketch on the selected face.
Draw the diagram of your bar.
Press the Leave Sketch button to finish.
Switch back to the BIM Workbench.
Select the sketch you just drew.
Press the Rebar button, or press R then B keys.
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).

Although normally a rebar is used inside an Arch Structure, since FreeCAD 0.19 the rebar can be created outside of any host object. To host a rebar inside an object, you just need to set its データHost.

オプション

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.
Default values for new rebars can be set in the Arch preferences settings.
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.
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.

プロパティ

An Arch Rebar object shares the common properties and behaviors of all Arch Components.

データAmount: The amount of bars.
データDiameter: The diameter of the bars.
データDirection: The direction (and length) along which the bars must spread. If the value is (0,0,0), the direction is calculated automatically from the host structural object.
データOffset Start: The offset distance between the border of the structural object and the first bar.
データOffset End: The offset distance between the border of the structural object and the last bar.
データRounding: A rounding value to be applied to the corners of the bars, expressed in times the diameter.
データSpacing: The distance between the axes of each bar.

Rebarツールは、マクロやPythonコンソールから次の関数を使って使うことができます：

Rebar = makeRebar(baseobj=None, sketch=None, diameter=None, amount=1, offset=None, name="Rebar")

Creates a Rebar object from the given baseobj, which is an Arch Structure, and a sketch as profile.
- diameter, amount, and offset are used to define the characteristics of the bars.
- If no diameter, amount, or offset values are given, the default values from the Arch Preferences are used.

例題:

import FreeCAD, Arch, Part

Structure = Arch.makeStructure(None, length=1000, width=1000, height=3000)
Structure.ViewObject.Transparency = 80
FreeCAD.ActiveDocument.recompute()

p1 = FreeCAD.Vector(-400, 400, 0)
p2 = FreeCAD.Vector(400, 400, 0)
Sketch = FreeCAD.ActiveDocument.addObject('Sketcher::SketchObject', 'Sketch')
Sketch.MapMode = "FlatFace"
Sketch.Support = [(Structure, "Face6")]
Sketch.addGeometry(Part.LineSegment(p1, p2))
FreeCAD.ActiveDocument.recompute()

Rebar = Arch.makeRebar(Structure, Sketch, diameter=80, amount=7, offset=50)
Rebar.OffsetStart = 100
Rebar.OffsetEnd = 100
FreeCAD.ActiveDocument.recompute()
