I believe the Zones still need to be improved a lot ..
My wish is to make the Zones displayable in ALL views in AC, as any other construction element and to have also the possibility of customizing the info that one wants to display in each of this views. (like for example the description according to the scale that exists in AC18 )
The other problem is the category of the zone..it should work as a custom profile that would apply any changes to all the zones from the category as it does the custom profile of a wall. For instance if you make a change in the category, only the colour changes to zones, but not other information..
