GuiCommand: Name: Part_Torus Name/cs: Díl_Torus MenuLocation: Díl -> Torus , Kompletace---

Description

Vytvoří jednoduchý parametrický torus podle parametrů pozice, úhel1, úhel2, úhel3, poloměr1 a poloměr2. Při vytvoření je torus umístěn do počátečního bodu (bod 0,0,0). Parametry úhly dovolují vytvořit částečný torus místo celého (úhly jsou defaultně nastaveny na 360°), poloměr 1 definuje vnitřní díru a poloměr 2 určuje tloušťku torusu.

A Part Torus can be turned into a segment of a torus by changing its Angle3 property. By changing its Angle1 and/or Angle2 properties the swept profile can become a segment of a circle.

Usage

  1. There are several ways to invoke the command:
    • Press the Torus button.
    • Select the Part → Primitives → Torus option from the menu.
  2. The torus is created.
  3. Optionally change the dimensions and Placement of the torus by doing one of the following:
    • Double-click the object in the Tree view:
      1. The Geometric Primitives task panel opens.
      2. Change one or more properties.
      3. The object is dynamically updated in the 3D view.
      4. Press the OK button.
    • Change the properties in the Property editor.
    • Change the Placement with the Std TransformManip command.

Example

Part Torus from the scripting example

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

Notes

  • A Part Torus can also be created with the Part Primitives command. With that command you can specify the dimensions and placement at creation time.

Properties

See also: Property editor.

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

Data

{{TitleProperty|Attachment}}

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

{{TitleProperty|Torus}}

  • Radius1|Length: The radius of the circular path of the torus. The default is {{Value|10mm}}.

  • Radius2|Length: The radius of the circular profile of the torus. The default is {{Value|2mm}}.

  • Angle1|Angle: The start angle of the circular profile. Valid range: {{Value|-180° <= value <= 180°}}. The default is {{Value|-180°}}.

  • Angle2|Angle: The end angle the circular profile. Valid range: {{Value|-180° <= value <= 180°}}. The default is {{Value|180°}}. If the total angle of the circular profile is smaller than {{Value|360°}} the profile will have a pie-shape.

  • Angle3|Angle: The angle of the circular path of the torus. Valid range: {{Value|0° < value <= 360°}}. The default is {{Value|360°}}. If it is smaller than {{Value|360°}} the resulting solid will be a segment of a torus.

Scripting

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

A Part Torus can be created with the {{Incode|addObject()}} method of the document:

torus = FreeCAD.ActiveDocument.addObject("Part::Torus", "myTorus")
  • Where {{Incode|"myTorus"}} is the name for the object.
  • The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

torus = doc.addObject("Part::Torus", "myTorus")
torus.Radius1 = 20
torus.Radius2 = 10
torus.Angle1 = -90
torus.Angle2 = 45
torus.Angle3 = 270
torus.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 45, 10))

doc.recompute()
