offsetcurvegenerator.

Only 2D linear features are supported as input. Self intersecting lines are not supported, and may produce unpredictable results. Other types of geometry will result in undefined behavior.

输出曲线中的每个点将是在接地单元中测量的指定偏移，远离输入的线性几何形状。输出端口LeftandRight将在线性几何形状的两侧产生偏移曲线。

This parameter, measures in ground units, specifies the distance by which the output curve is offset from the input curve.

As the diagrams below illustrate, the corner styles of the offset curves can be圆形的（默认），斜角（切碎），或Miter(pointed). IfMiter使用，必须使用限制使用Miter Limit范围。如果一个角落对斜角限制来说，拐角会被抛弃。

This parameter, measured in degrees, controls the smoothness of the stroked arcs in the output offset curve. As this parameter decreases in value, the smoothness of the arc connectors increases. The specified value must be between 0 and 90 degrees.

This parameter controls how pointed a buffered corner can be before it is bevelled. It is the highest value that the ratio of corner distance to offset is allowed to have before truncation occurs. A higher number allows for more extreme corner angles.
