For instance, the entity Line has a start marker and an end marker and the entity Circle has markers at quadrant points and a center marker. It is possible to change only one control point without affecting other ones with the help of markers.

2.Click left on the marker.
3.Move the control point of the object.
4.The following left click will finish editing the control point.
