Managing Multiple Floors in the Level Overview

Last modified: May 15, 2017

In CET Designer, you can draw custom floors and insert additional levels to handle those multi-story buildings. To create a basic, custom floor, please see the article Drawing Custom Floors and Adding Levels.

In this article, we’ll cover how to create multiple floors and how to manage custom and multiple floors in the Level overview. Here’s a picture to show how the interface will look when you are working with multiple floors:



Floor Categorization

When you place an object on a floor, it will automatically belong to the floor whose boundaries it is placed within. You can manually override this by selecting an object in the drawing area, going to the Floors tab in the Categorization dialog and selecting the floor(s) that you want the selected object to be assigned to. As soon as you select a checkbox, the Override floor designation at the bottom of the dialog will be automatically selected to allow this action.




Floor List

In CET Designer, the default setting is to show a basic rectangular floor in the 3D view that expands automatically to accommodate all the objects that you put in your drawing. This is labelled Base and refers to the default floor and the space that surrounds it. It will always appear at the bottom of the list and entails everything that is not specifically connected to or placed upon another floor.

Any time you create a custom floor it will be listed here and automatically named Floor 1, 2, 3 and so on (you can change the name manually).


Let’s take a closer look at what all the icons mean:

 FloorsDialogShowIcon_70  FloorsDialogHideIcon_70 Show / hide floor
 FloorsDialogLockIcon_70  FloorsDialogUnlockIcon_70 Lock / unlock floor movement
 FloorsDialogSolidIcon_70  FloorsDialogTransparentIcon_70 Solid / transparent floor
 FloorsDialogFloorName_70 Floor name
 FloorsDialogFloorElevation_70 Floor elevation
 FloorsDialogNumberOfObjects_70 Number of objects selected /  total number of objects on floor
 FloorsDialogAddNewFloor_70 Add a new floor on top of the selected floor. I
 FloorsDialogSelectAllObjectsOnFloor_70 Select all objects on floor
FloorsDialogRemoveFloor_70 Remove floor

The three icons above the list are for toggling visibility, lock and solid for all floors at once.

Selecting a floor in the list will highlight the corresponding floor in the drawing area and vice versa.

Hiding a floor in the list will also deselect the corresponding floor button at the bottom of the 3D view and vice versa.



Editing a Floor

Below the floor list, in the Edit section, you can adjust the floor in terms of floor name, elevation, thickness and ceiling height.

Here, you will also find a button leading to the Part Tagging dialog, since tagging floor works the same way as any other components. Note that when tagging a floor, the tag automatically applies to all objects placed on that floor as well.

There is also a button to access the Material Explorer and the option to save a certain material as default.

Floor Buttons in the 3D View

When you are working with one or more floors, new buttons become visible at the bottom of the 3D view. They are for toggling the floor visibility, i.e. showing or hiding floors in the drawing.


A black border indicates your currently active floor. Floors currently visible are indicated with a blue color. Left-clicking on a floor button toggles the visibility, while right-clicking on a floor button will change which floor is currently active.

Changing the floor visibility by clicking these buttons is also reflected in the Floor list and vice versa.



  • When working with multiple or custom floors, the default floor labelled Base is not really considered a true floor, but rather a place where all objects that do not belong to a certain floor are collected. This implies that anything that is placed upon or goes through a custom floor, for example walls, belongs to that floor. When you are working with multiple floors, we therefore recommend that you keep the Show floor boundaries option turned on, as it will make it easier to see which objects belong to which floor.
  • Not all Extensions will fully support the multiple floors functionality right away. Please contact your manufacturer for further details.


To select which floor(s) should be visible when rendering an image, please see the Photograph Setup: Floors article.
