You can apply point, line, and area loads in Revit. Each of these three load geometries is a family that contain instance and type parameters. Loads can be applied either by sketching or by using host components, such as floors and beams. You can edit load force and moment parameters before or after placing loads. Loads can be modified in magnitude and in case. You can also apply load combinations to your model (see Load Combinations). For more information about the properties of loads, see Load Properties.
