也可以把这种坐标，看成是空间中的极坐标，它其实使用了，距离原点的距离，然后用角度这种标尺，来确定了方向。

So, in a way, you can think of these as a space analog of polar coordinates because you just use distance to the origin, and then you have to use angles to determine in which direction you're going.

用于添加一个水平坐标尺寸。将一个端点连接到坐标原点，一个端点连接到部件。

Use to add a single horizontal ordinate dimension. Attach one endpoint to ordinate origin and one to the feature.
