what sort of wall surfaces?
I've recently completed a small clinic and to indicate (schedule & spec) the tiled wall surfaces areas I drew in a morph to each wall spaced about 20mm from the wall.
Its then easy to adjust where the tiled areas are in section and add necessary specs etc via Properties.
I could also schedule all the tiled areas
You say it's a big project so this method may not work for you, but maybe it can help you to work out something else.
