How to set element class (construction) for a specific level

if you want  those construction elements  for specific levels by  level name because you don't want them to print, then what we do at my work is we have the level names all start with CONSTRUCTION_ and  in the  level manager we set the  level to non printable... and when we  free the files for the drafters we  freeze the construction levels  off...

Thank you, Andrew Bell

Unfortunately, specific Levels cannot be defined as Primary or Construction class. You can however display any Construction Class element that have been placed on any level with specific Element Symbology using ByLevel Attributes.

You could also use Element Templates to possibly define the placement of elements to have Construction Class.
