Parts can be deconstructed. Select a part in the Tree Outline, then use the right mouse button option Explode Part to break the part into individual bodies. See Explode Part in the Context Menus section of the DesignModeler Menus chapter.
When you change the part-body grouping using Explode Part, the Share Topology feature is marked for regeneration if it is present in the model.
