Place levels in Revit

Learn how to use levels in Revit, including how to place a level in a model, change the name and elevation of a level, and constrain the top and bottom of a wall to a level.

This video demonstrates how to place level datums to establish a framework for the project.

00:12

Levels define floor levels of a building or other important datums, like the top of a foundation, or the roof plate height.

00:21

In a section or elevation view, use the Level tool to place a level.

00:26

By default, as you place a level, an associated plan view is created in the project browser.

00:32

Clear this option if you are creating a reference level for which no plan views are needed,

00:38

such as the top of a parapet, which is used only for reference.

00:42

As you place a level, snaps and guides help align the extents of the datum to existing levels in the project.

00:50

Click to define each end of the level line.

00:54

When you change the name of a level, the corresponding views in the project are changed as well.

00:59

Use controls in the drawing area to change the elevation of the level or select a level and make changes on the properties palette.

01:09

By default, when you place elements in a plan view, each element uses the associated level datum as a base constraint.

01:17

Other level datums in the project can be used to define constraints as well.

01:22

For example, if you place walls in the lower-level plan,

01:26

the bases of the walls are constrained to the lower level and the tops are constrained to the roof level.

01:32

When you place walls in the entry level plan, the bases of the walls are constrained to the entry level datum.

01:39

Top and bottom constraints establish the position of the wall in 3D space.

01:44

Because the tops and bottoms of the walls are constrained to a level,

01:48

when the level is moved, the tops and bottoms of the walls are moved as well.

01:53

All elements in the project are assigned and constrained to levels in order to establish their positions in 3D space.
