Using structural levels to apply a logical structure to a building

Structural levels allow you to apply a logical structure to a building. You can assign one or more drawing files to each structural level.

There are two different types of structural levels:

• Predefined structural levels: predefined structural levels may only be used in their hierarchical sequence. For example, a structure cannot be subordinate to a building. However, structural levels can be left out (e.g. a building can be subordinate to a project). The following five predefined structural levels are provided (in this hierarchy):
  • Site
  • Structure
  • Building
  • Story
  • Sub-story
• Any structural levels: in addition, you can use custom structural levels, which you can insert anywhere in the building structure.

Click Restrictions of building structure on the shortcut menu of a project to specify which structural levels can be used in the building structure and which structural levels can be assigned drawing files. For example, you can specify that only IFC-compliant structural levels can be used.
