Can somebody please take a quick look at this drawing and answer my queries regarding where to start? http://img.photobucket.com/albums/v385/CosRush/tiling.jpg I want to have the tiles at A central to the centreline from the units/extractor above. Should I start at A, then work towards each end? With regards to B, should I start in the corner with a whole tile or have any cut tile here? Same for C, should I start from the corner (B) with a whole tile or start at the other end at C and have any cut tile in the corner (B)?
