Why do put 0.24 (2:30) if the gallery's slab has a thickness of 0.23 ? Why do put -0.46 (4:47) if the slab above the entrance is set to 0.38 ? Why do put 0.00 (6:32) if in the top you have the roof ? Why one zone is set with +0.24 or -0.46 (positif or negative) ? And why do you have -0.1 under the zone (for each zone) Sorry too many "whys". Thank you.
