Description
The Part Cone command creates a parametric cone solid. In the coordinate system defined by its DataPlacement property, the bottom face of the cone lies on the XY plane with its center at the origin.
The default Part Cone is truncated. It can be turned into a full, untruncated, cone by changing its DataRadius1 or DataRadius2 property to zero. It can be turned into a segment of a cone by changing its DataAngle property.
Usage
- There are several ways to invoke the command:
- Press the Cone button.
- Select the Part → Primitives → Cone option from the menu.
Example
A Part Cone 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
Cone
- DataRadius1 (
Length
): Radius of the arc or circle defining the lower face - DataRadius2 (
Length
): Radius of the arc or circle defining the upper face - DataHeight (
Length
): Height of the Part Cone - DataAngle (
Angle
): Number of degrees of the arc or circles defining the upper and lower faces of the truncated cone. The default 360° angle creates circular faces, a lower value will create a portion of a cone as defined by upper and lower faces each with edges defined by an arc of the number of degrees and two radii.
Scripting
A Part Cone can be created using the following function:
cone = FreeCAD.ActiveDocument.addObject("Part::Cone", "myCone")
- Where
myCone
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
cone.Label = "new myConeName"
You can access and modify attributes of the cone
object. For example, you may wish to modify the lower or upper radius, the height or the angle parameters.
cone.Radius1 = 5
cone.Radius2 = 10
cone.Height = 50
cone.Angle = 270
The result will be a 270° portion of a full cone.
You can change its placement and orientation with:
cone.Placement = FreeCAD.Placement(FreeCAD.Vector(1, 2, 3), FreeCAD.Rotation(30, 60, 15))
