Multiple materials in a veeneer wall.

[Bob Moore]

How can you model a wall with more than one veneer material? i.e. something like a splitfaced block base with face brick above topped with a soldier course.

[Dwight]

You would consider the Wall accessories, where various things can be added to wall surfaces.
These applied elements understand window openings and edit with the wall.

With your walls selected look in: Extras> Accessories> Wall.....

Alternatively, you might need to apply some kind of profile to the wall surface, or even a second wall layer. It is more complex......

if, as dwight suggests, the accessories tools aren't complex enough for you, there is cigraph's 'ArchiWALL' product which lets you do all kinds of complicated wall-related manoeuvres!
