After a value engineering meeting, for cost reasons, decided to lowering the level heights of the project. We have 7 model and 3 drafting file and used groups for tower levels. When you change it one by one all the groups explodes you should lower them all by once. Challenge Accepted.
This is the definition. In this work flow Ground and first floor remain the same. Basements have specific heights and upper levels heights reduced 150 mm. (that means second floor -150, third -300). And we have Architectural and Structural levels in the same file :). That definition grab the level height find its number and reduce necessary difference.
