Arch Pipe/ja

説明
このツールを使用すると、最初から、または選択したオブジェクトからパイプを作成できます. 選択されたオブジェクトは、パーツベース（Draft/ドラフト、Sketch/スケッチなど）でなければならず、開いているWire/ワイヤが1つだけです.

使用方法

 * 1) Optionally, select a linear Part shape such as a Draft Line, a Draft Wire or an open Sketch.
 * 2) Invoke this command using several methods:
 * 3) * Pressing the button on the toolbar.
 * 4) * Pressing the then  keyboard shortcut.
 * 5) * Pressing the entry from the top menu.

オプション

 * Pipes share the common properties and behaviours of all Arch Components

プロパティ

 * : Sets the length of this pipe, when it is not based on a wire
 * : The diameter of this pipe, when it is not based on a profile
 * : The base wire of this pipe, if any
 * : The base profile of this pipe. If not given, the pipe is cylindrical.

典型的なワークフロー

 * Start by placing sanitary/hydraulic appliance items (below is an imported step file). You turn these objects into Arch Equipments by selecting them, and pressing the Arch Equipment button.




 * Arch Equipments now have a new SnapPoints property, which is a list of 3D vectors. This allows you to add custom snap points, to which you can snap when the new Draft Special snap button is turned on. Currently that property is only available to python, though. In the case above I added a new snap point at the exit of the wc appliance. The vectors inside SnapPoints appear on the model as white dots:

FreeCAD.ActiveDocument.Equipment.SnapPoints=[FreeCAD.Vector(0,0,100)]




 * With the new "Snap Special" Draft Snap, you can now snap to these custom points:




 * Now we can draw our piping using Draft Lines, Draft Wires, or Sketches. The best way, though, is using only Draft Lines:




 * There is now a new Draft Slope tool that allows to change the slope of Draft lines, to, for example, 5% (0.05). So we can quickly give our waste lines a correct slope. Only z coordinates are change by this tool, so we only need to snap them back to each other, the top projection will stay unchanged.




 * We now only have to select all our lines, and press the Arch Pipe button. Arch Pipe works with any Part-based object that contains one and only one open wire.




 * We can now create connections by selecting 2 or 3 coincident tubes, and press the Arch PipeConnector button. If 3 pipes are selected, two of them must be aligned in order to create a tee element:




 * Changing the connectors radius doesn't change the length of the underlying base line, only the resulting tube (by changing their OffsetStart or OffsetEnd property). So you can still draw your line layout with only straight lines, without the need to care about curves and radius.

It is also possible to create Arch Pipes without a base line, in this case use its "Length" property to define the length.

スクリプト処理
Pipe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：


 * Creates a object from the given  and.
 * is a Draft Line or Draft Wire.
 * If is omitted, a straight pipe can be created with just the  and the  in the Z direction.
 * If a is given, it is used.
