I am still having baby steps in learning this software.
-How can I assign the construction template to the floors that I drew? and how I can replace the current constructions with the new ones?
Thank you !!
The Construction Templates as defined in the Building Template Manager are only applied to new rooms that you draw.
To assign custom Constructions create them in the project Constructions Database then in a Thermal application such as Apache or VE Compliance select the rooms then use the Assign Constructions button to replace the current Constructions with your new custom ones.
There should be more on this in the user guide but that's it in a nutshell
