Levels
Buildings are segmented into levels in the vertical plane. When you create a project, you determine the number of
levels, their floor-to-floor height, and their floor elevation. When you add or remove levels, the project is updated with
the new level information.

Level Cut Plane
The cut plane is not set directly in the level. To set a cut plane for a level, you typically create a view for the level—for
example, “First Floor”—and set the cut plane height in the display configuration of the First Floor view. For more
information, see “
Working with Cut Planes in a Project ” on page 308.
Level Defaults
By default, the first level is present in each new project. It has a floor elevation of zero and represents the ground floor.
The unit in which the level height is displayed is dependent on the drawing defaults of the currently active drawing.
You can change the elevation value for the first level, which is then used as the default elevation for each new level
you insert.
Copying Levels with Constructs
You can quickly and easily duplicate floors with identical plans. After creating one level and assigning the floor plan
constructs to it—for example, a layout of apartments on the first floor—you can easily create new levels, which have
copies of the first level’s constructs assigned to them. You can edit and rename these constructs later in the Constructs
tab.
TIP If you duplicate floor plans in this way, a construct is created for each new level. If you edit the floor plan later, for
example, to add an extra door, you need to edit each level and construct individually. If your floor plans are going to be
absolutely identical, you can avoid this task. Create an element containing the floor plan, and reference it into the first construct.
Then copy the constructs to the levels. Each of the copied constructs have the same reference, and you can change them
quickly by changing the referenced element once.
For information on creating constructs and assigning them to levels, see “ Creating a New Construct ” on page 219.
For information on creating elements and referencing them into constructs, see “ Creating a New Element ” on page
233, and “ Attaching an Element as an External Reference to a Construct ” on page 225.
