The building's PARAMETERS file may
contain pre-defined parameter sets which refer to height levels not yet added to the
building. If you wish to take advantage of the pre-defined parameter sets, you can use the
name of such a height level. Notice however, that a height level existing in the
PARAMETERS file cannot be renamed or deleted in the 3D Levels dialog box. - Select the Type of the height level. Select
Floor for a main height level.

- Enter the Height of the height level. The height value of a main
height level is presented in relation to the absolute origin of the model.

- If necessary, select a floor structure from the list of the Floor or
ceiling field.

If you add a sub height level for a main height level, the default height of the sub height level is determined by the thickness of the selected structure.
- Confirm by clicking OK.
