Description
The Part Torus command creates a parametric torus solid, a doughnut shape. It is the result of sweeping a circular profile around a circular path. In the coordinate system defined by its DataPlacement property, the circular path of the torus lies on the XY plane with its center at the origin.
A Part Torus can be turned into a segment of a torus by changing its DataAngle3 property. By changing its DataAngle1 and/or DataAngle2 properties the swept profile can become a segment of a circle.
Usage
- There are several ways to invoke the command:
- Press the Torus button.
- Select the Part → Primitives → Torus option from the menu.
Example
A Part Torus object with the values of the bottom scripting example are shown here.
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
Torus
- DataRadius1 (
Length
): Radius of the circle around which the disc circulate - DataRadius2 (
Length
): Radius of the disc defining the form of the torus - DataAngle1 (
Angle
): 1st angle to cut / define the disc of the torus - DataAngle2 (
Angle
): 2nd angle to cut / define the disc of the torus - DataAngle3 (
Angle
): 3rd angle to define the circumference of the torus.
Scripting
A Part Torus can be created using the following function:
torus = FreeCAD.ActiveDocument.addObject("Part::Torus", "myTorus")
- Where
myTorus
is the user editable name for the object. - The function returns the newly created object.
The label text of the object can be easily changed by
torus.Label = "new myTorusName"
You can access and modify attributes of the torus
object. For example, you may wish to modify the radii or angle parameters.
torus.Radius1 = 20
torus.Radius2 = 10
torus.Angle1 = -90
torus.Angle2 = 45
torus.Angle3 = 270
The result will be a three-quarter torus.
You can change its placement and orientation with:
torus.Placement = FreeCAD.Placement(FreeCAD.Vector(1, 2, 3), FreeCAD.Rotation(30, 45, 10))
