Learn how to place levels in a model.
Levels establish a framework for the model. All elements in the model are assigned and constrained to levels in order to establish their position in 3D space. Levels are used to create the plan views of a model, which facilitate modeling and navigating in the model.
| Term/Concept | Definition |
|---|---|
| Level | Datum used in a model to establish the elevations of important features of the model. for example, the first and second floor of a building, the top of the parapet, or the top of footings. You can define any important vertical datum line in a model as a level. |
| Snaps and Guides | Aid in positioning and aligning elements as you place them in the model. As levels are placed, guides display so you can easily align the endpoints of the levels. |
| Level Properties | Describe aspects of the level and how it is defined in the model. The level name and elevation are examples of level properties. |
| Level Constraint | Controls properties of elements in the model that are assigned to a level. When the position of the level is changed, the positions of the elements assigned to the level are also changed. For example, walls in the model have a top and bottom constraint which can be associated with a level. |
