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 Part Cone button.
- Select the Part → Primitives → Cone option from the menu.
- A cone is created.
- Optionally change the dimensions and DataPlacement of the cone by doing one of the following:
- Double-click the object in the Tree view:
- The Geometic Primitives task panel opens.
- Change the required properties.
- The object updates dynamically in the 3D view.
- Press the OK button.
- Change the properties in the Property editor.
- Change the DataPlacement with the Std TransformManip command.
- Double-click the object in the Tree view:
Example
A Part Cone object created with the scripting example below is shown here.
Notes
- A Part Cone 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
Attachment
The object has the same attachment properties as a Part Part2DObject.
Cone
- DataRadius1 (
Length
): The radius of the bottom face of the cone. Can be0
if DataRadius2 is larger than0
. The default is2mm
. - DataRadius2 (
Length
): The radius of the top face of the cone. Can be0
if DataRadius1 is larger than0
. The default is4mm
. - DataHeight (
Length
): The height of the cone. The default is10mm
. - DataAngle (
Angle
): The angle of the circular arc that defines the top and bottom face of the cone. Valid range:0° < value <= 360°
. The default is360°
. If it is smaller than360°
the resulting solid will be a segment of a cone.
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))
