With this function objects can be unlocked from the drawing, ie. with a change of the original objects the attached outline will be re-adjusted with the object again.
If original objects were changed while the outlines where locked, a adjustment of the outlines will be done automatically.
Start the command Unlock with Menu Extras > Outlines > Unlock
With unlocking the outlines the option Lock outline will be deactivated for outline-objects in the tab Properties.
Is the option in the tab deactivated the outlines in the drawing follow automatically the object. If an exact check in desired, the option Check outlines can be used.
The changes only apply to the current group and its contents, but not to any other outline-objects in the drawing. If all outlines are supposed to be unlocked in the drawing the fuction has to be applied on the level of the group All.
