create a level for each known story or other needed reference of the building; for example, first floor, top of
wall, or bottom of foundation. To place levels, you must be in a section or elevation view.

Element: When creating a project, you add Revit MEP parametric building elements to the design. Revit
MEP classifies elements by categories, families, and types.
Category: A category is a group of elements that you use to model or document a building design. For
example, categories of model elements include walls and beams. Categories of annotation elements include
tags and text notes.
Family: Families are classes of elements in a category. A family groups elements with a common set of
parameters (properties), identical use, and similar graphical representation. Different elements in a family
may have different values for some or all properties, but the set of properties—their names and meaning—is
the same. For example, 6-panel colonial doors could be considered one family, although the doors that
compose the family come in different sizes and materials.
Families are either component families or system families:
■ Component families can be loaded into a project and created from family templates. You can determine
the set of properties and the graphical representation of the family.
