<html> <head> <style></style> </head> <body class='hmmessage'> So, In the exemple model i send in annex. The surface Wall-4 of the zone "Z3" is the same as Wall-2 zone "Z1" and that the same Wall-2 zone "Z3". But at the environment attributes (surface in another zone) of the surface can only bind to a surface by one zone. I can not connect the surface Wall-4 of the zone "Z3" to surface Wall-2 (Z2) and the Wall-2 (Z1). this will not affect the calculations? Once the surfaces( and zones) are not totally connected to each other.
