Part Cone

Description

The Part Cone command creates a parametric cone solid. In the coordinate system defined by its Placement 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 Radius1 or Radius2 property to zero. It can be turned into a segment of a cone by changing its Angle property.

Usage

1. There are several ways to invoke the command:
   • Press the Cone button.
   • Select the Part → Primitives → Cone option from the menu.
2. The cone is created.
3. Optionally change the dimensions and Placement of the cone 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

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 Cone 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|Cone}}

• Radius1|Length: The radius of the bottom face of the cone. Can be {{Value|0mm}} if Radius2 is larger than {{Value|0mm}}. The default is {{Value|2mm}}.

• Radius2|Length: The radius of the top face of the cone. Can be {{Value|0mm}} if Radius1 is larger than {{Value|0mm}}. The default is {{Value|4mm}}.

• Height|Length: The height of the cone. The default is {{Value|10mm}}.

• Angle|Angle: The angle of the circular arc that defines the top and bottom face of the cone. 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 cone.

Scripting

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

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

cone = FreeCAD.ActiveDocument.addObject("Part::Cone", "myCone")

• Where {{Incode|"myCone"}} is the name for the object.
• The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

cone = doc.addObject("Part::Cone", "myCone")
cone.Radius1 = 5
cone.Radius2 = 10
cone.Height = 50
cone.Angle = 270
cone.Placement = App.Placement(App.Vector(1, 2, 3), App.Rotation(30, 60, 15))

doc.recompute()
