If the tiles are simple (running or stacked pattern) draw a thin wall (1/4") to cover up the walls wich the tiles will be applied. This wall will be the tiles wall.
Make sure tiles wall has the texture of the tiles you want defined. You may create new materials with textures to suit your needs on options-elements attributes.
Make sure you turn on vectorial 3d hatching on model display on section selection settings, to see the tiles on 3d and in sections.
In a 3d view ,You may have to align 3d texture on design menu.
