look at the scope of work

Scope boxes control de visibility of datum elements. Grids, Levels and Reference Lines can be associated with Scope boxes, and the name of user created scope boxes are listed as an instance parameter in the datum properties. This is useful when we want to display datum elements in certain views but not in others.

Today in class, a student associated the levels to a scope box. After doing this, the levels projected in his South Elevation dissapeared.

The not-so-obvious reason was this:  The south elevation plane was NOT intersecting the scope box, therefore, preventing the levels to be displayed.   Remember that datum elements associated with scope boxes will only display IF a cutting plane intersects the scope box.
