Description
The Part Torus command creates a parametric torus solid.
FreeCAD creates a torus, with a radius 1 of 2 millimetre and a radius 2 of 10 millimetre.
By default, the torus is positioned with its mass center at the origin (0,0,0).
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.
Option
Parameter
A torus can be assimilated to a small disc that makes a circular orbit around an imaginary axe. Thus the parametric torus is defined by the following parameters:
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.
As well as the standard set of placement parameters. The pictures below give a visual overview of the parameters antecedently mentioned:
The parameter Radius1 has a value of 20 mm.
The parameter Radius2 has a value of 2 mm.
The parameter Angle1 has a value of -90°. Notice that, the 'angle measure' tool cannot display negative angle. Considered the displayed value in picture as '-90°'.
The parameter Angle2 has a value of 90°.
The parameter Angle3 has a value of 90°.
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))
