Erika — you may also want to look into Dynamic Components (DC), especially for field tiles. Here is a 3D warehouse link to a basic configurable floor tile DC:
Component Options allow you to configure the tile parameters and textures:
With SU Pro you can modify the attributes and behaviour of the DC itself: for example to make it a wall tile component (by changing the axis); or to embed favoured texture options; etc:
For sure there is a learning curve —and DC’s aren’t the first thing to learn in SU— but longer term, it may well be worth it for the type of design work you do. (or you could hire a developer to make/modify components for you.)
Hope this helps to reinforce your decision to go with SU,
Doug
