6.3 Clouds
A revision cloud is nothing more than a closed polyline created by arcs whose purpose is to highlight parts of a drawing on which you want to draw attention quickly and without much importance the accuracy of its parts.
Among its options we can modify the length of the arcs of the cloud, which will increase or decrease the number of arcs needed to create it, we can also convert an object, such as a polyline or an ellipse, into a review cloud and even change its style , which will modify the thicknesses of each arc segment.
