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.
The 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:
  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 DataPlacement 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

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 be 0mm if DataRadius2 is larger than 0mm. The default is 2mm.
DataRadius2 (Length): The radius of the top face of the cone. Can be 0mm if DataRadius1 is larger than 0mm. The default is 4mm.
DataHeight (Length): The height of the cone. The default is 10mm.
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 is 360°. If it is smaller than 360° the resulting solid will be a segment of a cone.

Scripting

A Part Cone can be created with the addObject() method of the document:

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

Where "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()
