{% embed url="<https://vimeo.com/871756476?share=copy>" %}

Capture 3 or more points around a circle to measure the radius, diameter, circumference or the area of a circle. Arc Path Type enables you to measure arc length, arc angle and segment area just as easily.

* Collect at least 3 points on the edge of the circle or arc
* All points must be on the circumference or the edge of the arc
* Spread your points across as much of the perimeter of circle
