Part Torus/zh-cn

描述
根据position, angle1, angle2, angle3, radius1 与 radius2参数创建一个简单的参数化环面.



如何使用
在零件工作台中点击环形图标. 这会在原点(point 0,0,0)处创建一个环形. 三个角度参数(angle1, angle2, angle3)与两个半径参数(radius1, radius2)用于确定参数化环形，详情请看下段文字.

参数

A torus can be assimilated to a small disc that makes a circular orbit around an imaginary axe. Thus the parametric torus is defined by the following parameters:


 * Radius of the circle around which the disc circulate
 * Radius of the disc defining the form of the torus
 * 1st angle to cut / define the disc of the torus
 * 2nd angle to cut / define the disc of the torus
 * 3rd angle to define the circumference of the torus.

as well as the standard set of placement parameters. The pictures below give a visual overview of the parameters antecedently mentioned:

The parameter Radius1 has a value of 20 mm.

The parameter Radius2 has a value of 2 mm.

The parameter Angle1 has a value of -90°. Notice that, the "angle measure" tool cannot display negative angle. Considered the displayed value in picture as "-90°".

The parameter Angle2 has a value of 90°.



The parameter Angle3 has a value of 90°.
