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.
