I ask this question since I imagine we all need to do this at some point.
What are the alternatives for tiling a bathroom when you really want to control where the tiles fall, and show thicknesses?
Typically, I have always just done vector hatch fils in 2D, and then made a lib part built from slabs the drawing if I really want/need to show the tiling in 3d.
Having parts/objects that on a render layer for this purpose is fine, just wondering what my fellow Archicad users do.
