    Usage

    Create

    1. There are several ways to invoke the command:
      • Press the Part Tube.svg Part Tube button.
      • Select the Part → Primitives → Part Tube.svg Create tube option from the menu.
    2. The Tube task panel opens and a preview of the tube is displayed in the 3D view.
    3. Specify the dimensions.
    4. The preview is dynamically updated.
    5. Press the OK button.
    6. The tube is created.
    7. Optionally change the DataPlacement of the tube in the Property editor, or with the Std TransformManip.svg Std TransformManip command.

    Edit

    1. Double-click the tube in the Tree view
    2. The Tube task panel opens.
    3. Change one or more dimensions.
    4. The tube is dynamically updated in the 3D view.
    5. Press the OK button.

    Example

    Part Tube from the scripting example

    A Part Tube object created with the scripting example below is shown here.

    Properties

    See also: Property editor.

    A Part Tube object is derived from a Part Feature object and inherits all its properties. It also has the following additional properties:

    Data

    Attachment

    The object has the same attachment properties as a Part Part2DObject.

    Tube

    • DataHeight (Length): The height of the tube. The default is 10mm.
    • DataInner Radius (Length): The inner radius of the tube. Must be smaller than DataOuter Radius. Can be 0. The default is 2mm.
    • DataOuter Radius (Length): The outer radius of the tube. Must be larger than DataInner Radius. The default is 5mm.

    Scripting

    See also: Autogenerated API documentation, Part scripting and FreeCAD Scripting Basics.

    A Part Tube can be created with the addTube() method (introduced in version 0.20) of the Shapes module:

    tube = Shapes.addTube(FreeCAD.ActiveDocument, "myTube")
    
    • Where "myTube" is the name for the object.
    • The function returns the newly created object.

    Example:

    import FreeCAD as App
    from BasicShapes import Shapes
    
    doc = App.activeDocument()
    
    tube = Shapes.addTube(FreeCAD.ActiveDocument, "myTube")
    tube.Height = 20
    tube.InnerRadius = 2
    tube.OuterRadius = 3
    tube.Placement = App.Placement(App.Vector(2, 4, 5), App.Rotation(60, 60, 30))
    
    doc.recompute()
