Description

描述

在零件工作台中，可以通过零件工具栏、Part菜单（中的primitives子菜单）或Create Primitives（创建图元）对话框来创建参数化的截断零件圆锥图元。

The default Part Cone is truncated. It can be turned into a full, untruncated, cone by changing its 数据Radius1 or 数据Radius2 property to zero. It can be turned into a segment of a cone by changing its 数据Angle property.

Usage

如何使用

Example

Part Cone from the scripting 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.

选项

Cone

  • Radius 1 - 定义底面弧或圆的半径
  • Radius 2 - 定义顶面弧或圆的半径
  • Height - 零件圆锥体的高度
  • Angle - 定义截断圆锥体顶面与底面上弧或圆的角度值。默认值360创建的顶底皆为圆面，较小值将创建出不完整的部分圆锥，具体形状取决于实际角度与两个半径所定义的弧，乃至顶面与底面。

A Part Cone 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

  • 数据Radius1 (Length): The radius of the bottom face of the cone. Can be 0mm if 数据Radius2 is larger than 0mm. The default is 2mm.
  • 数据Radius2 (Length): The radius of the top face of the cone. Can be 0mm if 数据Radius1 is larger than 0mm. The default is 4mm.
  • 数据Height (Length): The height of the cone. The default is 10mm.
  • 数据Angle (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

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

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()
