Parts and substructures in a model can originate from different sources. In Structure Edit mode you can use the Transform and Assemble tools to assemble multiple data sets into new sBOMs with fully assembled data. In Structure Edit mode you can move parts only if the parts are selected in the sBOM tree, not if they are selected in the eBOM tree or the Figure view. The sBOM locations are initial positions for parts in new figures. New sBOM locations do not override figure locations in previously saved figures.
