From the 3D View, a 2D view can be activated to edit a specific selected element. To edit a slice, a contour , a dot set or a path, right click on it in the Object Explorer and select the option Edit Slice, Edit Contour, Edit Dot Set, or Edit Path from the context menu. If the element to be edited is visible in the scene, its context menu can also be displayed directly from the 3D View (see specific instructions).
In the case of a path with visible nodes and labels, open the context menu associated to a node and select the option Edit Path - Slice <nr> to edit the path at the slice number <nr>, which is the slice the node belongs to. See Select and display a context menu of a path directly from the 3D scene.
