Description

描述

利用位置、角度、半径与高度参数创建一个简单的参数化圆柱体。

A Part Cylinder can be turned into a segment of a cylinder by changing its 数据Angle property.

如何使用

在零件工作台中点击此图标。默认情况下，此工具会创建一个对齐于坐标轴的半径为2mm且高度为10mm的完整圆柱体，并令其中心与全局原点(point 0,0,0)重合。

There are several ways to invoke the command:
- Press the Part Cylinder button.
- Select the Part → Primitives → Cylinder option from the menu.
The cylinder is created.
Optionally change the dimensions and 数据Placement of the cylinder 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 数据Placement with the Std TransformManip command.

Example

A Part Cylinder object created with the scripting example below is shown here.

Notes

A Part Cylinder can also be created with the Part Primitives command. With that command you can specify the dimensions and placement at creation time.

选项

创建圆柱体后，用户可编辑其数据选项卡中的各属性：

Data

Attachment

The object has the same attachment properties as a Part Part2DObject.

Cylinder

数据Radius (Length): The radius of the circular arc that defines the cylinder. The default is 2mm.
数据Height (Length): The height of the cylinder. The default is 10mm.
数据Angle (Angle): The angle of the circular arc that defines the cylinder. Valid range: 0° < value <= 360°. The default is 360°. If it is smaller than 360° the resulting solid will be a segment of a cylinder.

Prism

数据First Angle (Angle): The angle between the extrusion direction of the cylinder and its positive Z axis, measured around its Y axis. The angle is positive towards its positive X axis. Valid range: 0° <= value < 90°. The default is 0°. introduced in version 0.20
数据Second Angle (Angle): The angle between the extrusion direction of the cylinder and its positive Z axis, measured around its X axis. The angle is positive towards its positive Y axis. Valid range: 0° <= value < 90°. The default is 0°. introduced in version 0.20

Scripting

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

cylinder = FreeCAD.ActiveDocument.addObject("Part::Cylinder", "myCylinder")

Where "myCylinder" is the name for the object.
The function returns the newly created object.

Example:

import FreeCAD as App

doc = App.activeDocument()

cylinder = doc.addObject("Part::Cylinder", "myCylinder")
cylinder.Radius = 10
cylinder.Height = 50
cylinder.Placement = App.Placement(App.Vector(5, 10, 15), App.Rotation(75, 60, 30))

doc.recompute()
