When you need to measure inclined or non-standard objects, you will need the continuous measure feature.
Attention: An arc could be automatically recognized when the mouse turns into a small white square. If the mouse turns into a small yellow square, it means it’s not an arc but a polyline that consists of multiple line segments, and you need to select them one by one for measurement. The arc can be interrupted if you think it is too long. Just move the mouse and find the intersection point where you want to stop it and left-click on it.
