Changes made to one part of a project frequently influence other parts of the project. The following information describes the changes you can make to a level and the effects of the changes on other parts of the building project:
- Adding new levels: When you add a new level to a project, you must assign constructs. You also need views and sheets to represent that level.
- Changing the level name: When you change the name of a level, the constructs assigned to it are automatically updated to reference the new name. For example, if you change the name of a level from 1 to First Floor, the constructs assigned to that level are automatically updated to be assigned to First Floor.
- Changing the level ID: Level IDs can be used in schedule tables. If you change the information here, the information in your schedule table changes.
- Changing the floor-to-floor height of a level: When you change the floor-to-floor height of a level and you have selected Auto-Adjust Elevation, the floor-to-floor height of all the levels are adjusted. The multi-level view regenerates to adjust for the change in height. For example, if you change the height of the first floor from 3 meters to 4 meters, the elevation of the second level changes from 3 meters to 4 meters. If you have chosen not to auto-adjust levels, you need to update all other levels manually to avoid gaps or overlapping levels. In any case, make sure that the objects in the assigned constructs retain the correct height for the level after changing it. That way, you avoid displaying 4 meter walls in a 3 meter level.
- Changing the floor elevation of a level: If you are changing the elevation of a level and you have selected Auto-Adjust Elevation, the elevation of all the levels are adjusted. The multi-level view regenerates to adjust for the changes in elevation.
- Deleting a level: When you delete a level, constructs assigned to that level are not deleted with it. They remain in the project, but they are “orphaned,” that is, they have lost their level. You can choose what to do with them:
- Delete them, because the level on which they are placed no longer exists.
- Assign them to a different level within the project.
-
When you delete a level that has been used for a view, the view is not deleted from the project. If you update the view, however, it is missing this level. You can choose among these actions:
- Delete the view, because the level it was displaying no longer exists.
- Create a new selection set for the view.
