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面图标. 这会在原点(point 0,0,0)处创建一个环面. 三个角度参数(angle1, angle2, angle3)与两个半径参数(radius1, radius2)用于确定参数化环面，详情请看下段文字.

选项


参数

创建环面的过程就相当于令一个小圆盘沿一个幻想的环形轨道为轴进行圆周运动. 这样，就可以通过下列参数来定义参数化环面：


 * 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°.
