The following illustration shows a body on which a circumferential cut-out has been made in the upper half.
This means that the upper surface has dependencies on several 3D history [3D History] elements.
Under these circumstances, it was not permitted in versions 12.6 to 12.11 to use the Create new sketch on selected area [Generate sketch on selected face], Create new layer on selected area [Create plane on selected Face] and Create new text on selected area [Generate text on selected face] features. These features were only available for test purposes. The corresponding context menu commands were deactivated by default. With V12.12, the use of these features is now also permitted and officially released for sketch relationships to several 3D history [3D History] elements.
