I would like to know how to activate your zone before you start the modeling
because when i tried to export the file to simulation studio , i find a problem which require me to activate the zone in sketchup in order to run the simulation in simulation studio
the problem is that made a simple model of cube in thermal zone through the trnsys3d plugin for google sketchup and i tried to export the IDF file in order to run the simulation in trnsys
for the beginnig , all was good and i succed to export the IDF file and i ran the simulation correctly , this case was when i export the IDF file directly without any change in the definition of the adjacent conditions of the walls
but in fact , i need to change the adjacent conditions of the walls , so when i did that , the simulation studio didn’t accept the IDF file
