I'm not sure about your request. There is special attribut which can be use in many object and in link to any modules. Like the lenght.
The lenght can be use for many architectural object, 2D element, precast element and also fixture.
But for the engineering, there is other attribut like: @797@ which is also a lenght, or @760@ (Total lenght) and @757@ (Mesh and bar lenght).
Are they what you need?
Bye & Good Use!
