Revit 3D create a row of 3D images remove covered overlap areas from already existing Revit file

$40 We have a single town home in Revit, 3D, fully drawn up. We need to make a ROW of townhomes - a whole street - by joining side by side 20 town homes, each copies of the other. There are two views of the townhome - each of the two long sides. The homes join in particular positions, such as not to have outside decks overlap, for privacy of occupants. The covered area of the townhome that results from this joining should not be shown in any way, to not create confusion. The angle of the 3D renderings will need to be adjusted at the start to accommodate the exact positioning of the townhomes next to each other - otherwise the street will look odd. This is not an architectural job as such - it is a graphics job. In all likelihood this is most efficiently and easily done in Revit.
